  • a tight coil of strip metal is rewound with a spacer strand, which may be in the form of a string, corrugated metal strip or the like, in between the laps.
  • the thickness of the spacer strand is such that the desired lap spacing is established.

  • the vertical position of the belt 7 is so adjusted that the bottom edge of the strip S as it leaves the driven bridle roll 5 Will be at an elevation slightly above the top face of the open coil turntable T.
  • an adjustable upper edge guide unit G similar in its essential parts to the edge guide G, is adapted to engage the upper edge of the strip S and prevent vertical movement thereof. It will be understood that this upper edge guide unit G may be adjusted vertically to accommodate different widths of strip.
  • a pair of bridle rolls 4 and 5 around which the strip passes.
  • the first bridle roll 4 is not driven and rotates with the strip as it moves thereover. Its function is to maintain the necessary circumferential contact of the strip with the surface of the second bridle roll 5 which is driven through shaft 13, gear box 14 and motor 15.
  • the roll 5 is driven at a constant speed and accordingly the strip S will be advanced toward the turntable T in the direction of the arrow at a constant lineal velocity.
  • a snubber roll 16 is adapted to coact with roll 5.
  • This snubber roll also assists in guiding the strip S in proper direction toward the loose coil turntable T and is driven through shaft 17 and gear box 18 by a motor 19.

  • the open coil turntable T on which the open coil C is formed and supported, is driven by a vertical shaft 20 which in turn is connected to the variable speed electric motor 21 through the angle gear box 22. It will be understood that in the apparatus of FIGURE 1, as the strip S is fed to the turntable T at a constant velocity, the speed of rotation of the turntable T will have to be progressively reduced as the diameter of the open coil C builds up.
  • the steel strip material for which my invention is particularly adapted may have a thickness or gage !of from about .010 up to about .08" or greater, while the space between the adjacent surfaces of adjacent laps of the completed open coil will ordinarily vary from about /2 to about 3 times the strip thickness.
  • the finished open coil may be as much as 10' in outside diameter
  • variable speed unit F As illustrated this unit is .of the type known as a ball and disc integrator but it will be understood that other equivalent devices may be employed.

  • a driven element in the form of a disc 29 is enclosed within the housing 30 of the .unit F and has an upwardly extending cylindrical portion 31 which is supported in bearings 32 and 33 in housing 30.
  • the shaft 34 extends from portion 31 through the top of housing 30 and is driven by and rotates with the disc 29.
  • the variable speed unit F also has an adjustable or variable means for effecting driving connection between the driving element 23 and the driven element 29 and varying the speed of the driven element 29 relative to that of the driving element 23.
  • This means includes the shaft 35 which extends generally parallel to drum 23 and has a bearing 36 in housing 30. The inner end of shaft 35 is threaded to form a feed screw 37 which has threaded engagement with a movable traverse block member 38.
  • This block 38 is supported between the drum 23 and the disc 29 and has a cylindrical hole 39 extending vertically therethrough in which are disposed a pair of superimposed steel balls 40 and 41. These balls are of a diameter to have a close rotational fit in the hole 39 and, when held therein, extend between the drum 23 and the disc 29 and effect a driving connection therebetween.
  • variable speed unit F the variable speed unit
  • this unit may take other forms than the ball and disc integrator device illustrated, it will now be explained how the desired speed control of the turntable T is effected.
  • variable speed turntable drive motor 21 is connected at its left hand end (FIG. 1) to drive the turntable T.
  • a shaft 42 extends from the right hand end of motor 21 and is connected to shaft 43 through an angle gear box 44.
  • the adjustable variable speed control unit 45 preferably having a wide range of speed variation, is disposed between shaft 43 and shaft 46. By adjusting the regulator handwheel 45 of unit 45 the speed of shaft 46 may be varied relative to the speed of shaft 43 over a considerable range.
  • Angle gear box 47 establishes driving connection between shaft 46 and shaft 48 which is connected through a speed reducer 49 and clutch 35 to shaft 35 of the variable speed unit F
  • These driving connections between the motor 21 and the unit F are adapted to actuate the adjustable means 38, 40, 41 of unit F to cause same to traverse the disc 29 and thus effect progressive variations in the speed of driven element 29.
  • variable speed unit F and the balls 40 and 41 (which constitute an adjustable means for varying the speed of driven element 29 relative to that of driving element 23) will be moved radially of the disc 29 .by the feed screw 37 at a rate of travel which will vary directly with variations in the rate of rotation of the open coil turntable drive motor 21.
  • the actual rate of movement of the block 38 and the balls 40 and 41 across the face of disc 39 for any given speed of rotation of motor 21 may be varied by adjusting the speed control unit 45 through its regulator 45 and, as will be explained more fuly later, this speed control unit 45 comprises means for adjustably varying the rate at which the ratio between the speed of rotation of the turntable and the speed of feed of the strip is changed. This enables my apparatus to be set to form an open coil having any desired spacing of the laps and to accommodate coils of different strip thickness.
  • the vertical shaft 34 which rotates with the driven disc 29 is connected through a gear box 50 to a shaft 51 which in turn drives a tachometer type generator unit 52.
  • This unit 52 is adapted to generate an electrical current which varies in accordance with the speed at which it is driven.
  • the electrical output of unit 52 is conducted through wires 53 to the control unit 54- to which electrical supply lines 55 are connected from any suitable source of current and from which the wires 56 extend to the variable speed turntable drive motor 21.
  • the function of the control box 54 is to vary the current supplied to motor 21 in accordance with variations in the control current from the generator unit 52 in such a manner that, as the disc 29 and generator 52 slow down, the motor 21 will correspondingly slow down.
  • the specific type of electrical control apparatus employed in unit 54 to effect this result forms no part of the present invention and any suitable control means, responsive to the speed of the driven element of the variable speed unit F for varying the speed of rotation of the open coil turntable drive motor 21, could be employed.
  • variable speed unit F Before the start of a coil opening operation the variable speed unit F must be set at its start position with the balls 40 and 41 at their innermost position relative to the disc 29. This may be effected by disengaging the clutch 35 between shaft 35 and speed reducer 49 and turning shaft 35, by any suitable means (not shown) sothat the screw 37 moves the block 38 inwardly (to the right as seen in FIGS. 1 and 2) until the established starting position is reached. For purposes of this explanation this may be considered to be the position seen in FIGURE 2 of the drawings.
  • Clutch 35 is then reengaged and the strip S from the tight wound coil C is led through between the edge guides G and G and around the bridle rolls 4 and 5 and its forward end secured to a mandrel M or other anchoring device on the turntable T.
  • the diameter of mandrel M is, of course, equal to the desired inside diameter of the open coil that is wound therearound.
  • variable speed control unit 45 is set by adjusting the regulator 45' to give the desired and pro-determined ratio between the speed of the motor 21 and the speed of shaft 4'6.
  • the speed of rotation of shaft 46 determines the speed of rotation of shaft 35 and screw 37, and accordingly determines the rate of traverse of the block 33 and the balls 40 and 41 across the face of disc 29 relative to the speed of rotation of motor 21.
  • the direction of rotation of shaft 35 is such that the block 38 will be traversed to the left from the start position seen in FIGURES 1 and 2.
  • the drum 23 of the variable speed unit F rotates at a speed which is proportional to the lineal speed of the strip toward the turntable T.
  • the starting of the bridle roll motor 15 also signals the motor 21 to start.
  • the screw 37 will start to rotate in the unit F and the block 38 and balls 40 and 41 will start to travel to the left.
  • the speed of rotation of the disc 29 will be progressively reduced. This results in a corresponding reduction in the electrical output of the tachometer generator 52 which in turn, through the control box 54, results in a progressive reduction in the speed of rotation of motor 21 and the turntable T.
  • the adjustable speed control unit 45 which enables the ratio between the speed of rotation of the turntable drive motor 21 and the variable speed unit traverse shaft 35 to be varied through a substantially infinite number of in- 6 crements and over a relatively large range, enables the rotation of the open coil turntable T to be so controlled that any gage or thickness of strip, Within the design limits of the apparatus, may be recoiled into open coil form with any lap spacing within the designed range of the apparatus.
  • the unit 45 is preferably provided with indicating means, not shown, whereby the proper adjustment may be visually set, the setting for any given gage and lap spacing being based upon calculations and arranged in tabulated form according to strip gage or thickness and desired lap spacing for convenience in operating the apparatus.
  • variable speed control unit 45 By precalcuating the lengths of strip in the tight coils it is also possible to set the variable speed control unit 45 to produce open coils all with the same outside diameter, regardless cf the diameter of the original tight coil. This is advantageous when the open coils are heated in a furnace.
  • the shaft 24 of the variable speed unit F might be driven by an independent constant speed driving means but I prefer to correlate the speed of rotation of the constant speed member of the unit F with the speed of rotation of the driven strip feed roll 5.
  • the correlating means is illustrated as a mechanical connection it will be understood that it could readily be electrical in nature.
  • the bottom edge guide unit G determines the vertical position of the bottom edge of the strip S as it enters, and also as it leaves, the bridle rolls 4 and 5.
  • the bottom edge guide G is preferably so adjusted that the bottom edge of strip S will be disposed a short distance above the top surface of the outer periphery of the turntable T as it moves past this point during a coiling operation. In practice a setting of guide G which establishes this distance at about one-half inch has been found satisfactory in forming open coils up to 8 to 10' feet in outside diameter.
  • a coil might be for-med with three laps in engagement followed by six spaced apart laps, then three more laps in engagement, etc.
  • This type of coil is particularly advantageous in the annealing of light gage strip material where such a coil formation enables the outside diameter of the open coil to be reduced, or the length of strip in a coil of given outside diameter increased, While still providing sufiicient heat transfer surface to effect the desired results.
  • Such a coil may readily be :formed with my apparatus by varying the adjustment of the speed control of unit 45 as the rewound coil is being built up.
  • the setting of the unit 45 would be maintained at a value to give engaging laps for the time required to form three revolutions of the turntable T.
  • the setting of the unit 45 would then be shifted to give the desired lap spacing and maintained at this setting for the time required for six more laps to be laid down. The setting would then again be returned to the first value for another three laps, and this cycle repeated until the complete coil is formed.
  • Such cycling of the unit 45 might be effected by manual manipulation by the regulator 45' or by suitable automatic means.
  • the apparatus illustrated in FIGURE 1 is arranged for, and adapted to operate by, feeding the strip at a constant rate toward the open coil turntable and varying the speed of the turntable to effect the desired spaced apart lay-up of the laps of the open coil on the turntable surface.
  • the same result may be obtained by rotating the turntable at a substantially constant speed of rotation and varying the speed of feed (lineal velocity) of the strip to the turntable. in such an operation the speed of feed of the strip will be progressively increased as the diameter of the open coil builds up on the turntable with resulting progressive change in the ratio between the speed of feed of the strip and the speed of rotation of the turntable.
  • FIGURE 3 of the drawings The apparatus illustrated in FIGURE 3 of the drawings is designed for such an operation. In this view similar parts are identified by the same reference characters as were employed on FIGURE 1.
  • the open coil turntable T in FIGURE 3 is driven at a constant speed of rotation by the motor 21.
  • the speed of drive motor 15 for the driven bridle roll 5 is progressively increased during an open coil forming operation so that the speed of feed of the strip S will be progressively increased as the coil is formed on the turntable T.
  • variable speed unit F similar to that shown in FIGURES 1 and 2, is provided.
  • the disc 29 constitutes the driving element and is rotated at a constant speed through shaft 60, angle gear box 61, shaft 62, angle gear box 63, and shaft 64 which is driven from constant speed motor 21 through gear box 22.
  • the drum 23 of unit F is the driven member and the driving connection between disc 29 and drum Z3 is effected through a pair of balls carried by the traverse block member 38 which has threaded engagement with the feed screw on the end of shaft 35 as best seen in FIGURE 2.
  • Rotation of the feed screw shaft 35 is effected from the motor 21 through the shafts 43, variable speed control unit 45, shaft 46, gear box 47, shaft 48, reduction gear 49 and clutch 35'.
  • the driven drum member 23 of the variable speed unit F is supported by and rotates shaft 65 which in turn drives a tachometer generator '66.
  • the signal from this tachometer generator 66 is conducted through Wires 67 to the control unit 68 to which the main supply line 69 is connected.
  • Wires 70 extend from control unit 68 to the strip feed drive motor 15.
  • the drive motor 19 of the snubber roll '16 is connected by wires 71 to the line 70 so that the speed of rotation of the snubber roll 16 will be varied in the same manner as the speed of rotation of the bridle roll 5.
  • the drum 23 When the open coil forming operation is first started the drum 23 will be rotated at a relatively slow speed and the signal from the tachometer unit 66 will so control the current supplied to the motor 15 through the control unit 68 that the motor 15 will drive the roll 5 to feed the strip at the proper relatively slow lineal velocity.
  • the traverse block 38 and balls 41 and 40 move radially outwardly of disc 29 and, as disc 29 rotates at a constant speed, the speed of the drum 23 and the tachometer unit 66 will be progressively increased. This increase, through control box 68, will progressively increase the speed of rotation of motors 15 and 19 and effect a corresponding increase in the lineal speed of the strip S as it is fed to the turntable T.
  • the ratio between the speed of feed of the strip and the speed of rotation of the turntable will progressively change.
  • the rate at which this progressive change is effected will determine the radial position on the turntable T at which each increment of length of the strip S will be laid down and thus Will control the space between the laps of the open coil.
  • Changing the speed of traverse of the block 38 outwardly of the disc 29 will vary the rate of change in the ratio between the speed of feed of the strip and the speed of rotation of the turntable T and such change may be effected by regulation of the variable speed control unit 45 through the bandwheel 45 or other suitable means.
  • FIGURES 1 and 3 the proper relation between the speed of feed of the strip and the speed of rotation of the open coil turntable to form an open coil having the desired spacing between the laps is effected largely by mechanical means. It is entirely practical, however, to effect the desired control of this relation through means which are largely electrical in nature and in FIGURE 4 I have diagrammatically illustrated such an arrangement.

  • the strip feed motor 76 drives a tachometer generator unit 84 through a shaft 85 and the signal from this unit 84 is impressed upon the regulator unit 82 through line 86 while a similar signal is impressed upon the regulator unit 83 through line 87.
  • the open coil turntable motor D also drives a tachometer generator unit 88 through a shaft 89 which also extends to an adjustable variable speed control unit 90 which may be regulated as by a handwheel to vary the ratio between the speed of motor shaft 89 and the speed of shaft 91 which extends to a reduction gear unit 92.

  • the contact arm 95 is moved progressively in clockwise direction and decreases the resistance interposed by potentiometer P in line 96' with consequent increase in the voltage applied to regulator 83 through line 96 and reduction in the voltage applied to the generator field 80 through line 102.
  • the strength of the field 30 of generator G will be progressively reduced with corresponding reduction in the output of generator G and the speed of turntable motor D. Due to the progressive reduction in speed of motor D the rate of travel of the contact arm 95 of potentiometer P will not be constant but will be diminishing in nature. As has been previously explained, the diminishing rate at which the speed of the turntable drive means is reduced effects the formation of a coil having uniform spacing between the laps thereof. By properly regulating the variable speed control unit 90 the rate of travel of contact arm 95 may be varied to obtain the desired space between laps for the particular strip thickness being handled.
