Definitions

  • FIG. 1 A first figure.
  • This invention relates to a novel method and apparatus for guiding and aligning traveling webs of various materials such as paper, fabrics, etc. of varying gauge and flexibility, and especially to novel method and apparatus for correcting misalignment of the web without causing wrinkling or otherwise damaging the web.
  • the web shall contact the abutments with minimum possible friction, especially for fragile webs, and our invention contemplates improvements whereby such minimum friction is effected through the employment of rotary abutments and the web made to pass through said helical paths and correct misalignment without wrinkling or damaging the web, all as hereinafter more specifically described.
  • An important feature of the invention relates to the employment of a rotary abutment in the form of a cylindrical roller having a plurality of web supporting bars extending longitudinally thereon at its periphery and disposed in parallel relation concentrically about the rotary axis of the roller, the bars being movable both forwardly and laterally with the web and thereby conducting the web freely in a helical path on and about the roller without placing appreciable tension on the web.

  • FIG. 18 is a plan view partly in section of a segmented roller utilized to change the direction of travel of a web.
  • FIGS. 1-5 it indicates the supporting base of our web guiding device which is adapted to be fixed to and supported on the machine employed for feeding the traveling web 12.
  • the machine is adapted to feed the web forwardly in the direction indicated by the arrows and the function served by our invention is automatically to maintain the web in true feeding alignment and including the automatic correction of any misalignment that may develop as the web travels forwardly, as to a rewinding roll 14.
  • Two parallel web guiding rolls 15 and 17 are rotatably supported on the base 10 and our web guiding mechanism is disposed between these rolls to receive the web from the roll 15 and deliver it to the roll 17.
  • Our Web guiding mechanism as illustrated in FIGS. 1-5 employs two parallel web supporting abut-ments 18 and 26, both comprising rollers rotatably mounted at their ends in the upright portions 21 of a frame including a tubular bar 22 rigidly supporting the two uprights at its two ends.
  • the frame is mounted for pivotal movement on a post 24 extending through the bar and supported in a yoke 25 carried on the base lit.
  • the rolls 15 and 17 are disposed right-angularly across the web 12 and in the normal position of the frame 2122 the abutments 13 and 2% are parallel with the rolls 15 and 17.
  • the pivoting of the frame is under the control of automatic sensing mechanism herein indicated as a sensing finger at 26 in contact with one edge of the web 12 and frame pivoting mechanism including a cylinder 27 having a piston therein provided with a piston rod 28 connected to the bar 22.
  • the arrangement is such that under normal conditions and when there is no misalignment in the web the frame 2122 will remain in its normal position. However, should the web deviate laterally in one direction or the other the finger 26 Will follow the web and cause pivoting of the frame in a direction to correct the misalignment.
  • Such sensing mechanisms are known in the art, as for example, in Patents 2,291,830 and 2,814,- 487, and per se form no part of this invention.
  • the web 12 is fed forwardly in a plane path P (FIG. 3) onto and arcuately about the roller 18, from thence rearwardly to and arcuately about the roller 20, and from thence forwardly in a second plane path P parallel with the path P.
  • the sensing finger 26 is disposed to contact the edge A of the web forwardly of the roller 20. If, for example, the entering portion of the web at P shifts gradually to the left (FIG. 2) a distance Y from its normal position, the finger 26 will sense the change and cause pivoting of the frame 21-22 to an angular position to correct the misa ignment.
  • this lateral shifting of the web is immediately sensed by the finger 26 which, operating through the cylinder 27, functions immediately to correct the misalignment and such functioning continues so long as there is any continued increase in the amount of misalignment.
  • this angular displacement of the rollers 18 and 26 causes the web to move to the right. During such movement the web remains in contact with the finger 26 thereupon causes the frame 21-22 to remain in such position as will continue to correct the misalignment.
  • Our invention contemplates novel means for eliminating this difficulty and substantially eliminating the frictional relation between the web and at least one roller.
  • We accomplish this object by making one or both of the abutments 18 and 20 a segmental roller in which the web engaging and supporting portions not only rotate with the roller but also travel longitudinally therealong with the lateral movement of the web. This mechanism as illustrated in FIGS. lwill now be described.
  • FIGS. 1-5 we have illustrated the abutment 18 as embodying a plain cylindrical roller and the abutment 2b as embodying a segmented roller.
  • the segmented roller includes two flanges 30 fixed in spaced relation on an axle 32 mounted to rotate in bearings 33. Supported for free longitudinal movement in aligned bushings 34 in the flanges are a plurality of bars disposed concentrically about the axle, each bar embodying a web supporting shoe 36 having end portions 37 welded thereto and slidable longitudinally in the bushings 34.
  • the shoes illustrated are of T-shape and are supported for rotation with the axle by rollers 38 riding in longitudinal channels 40 in a hub 42 secured to the axle as by a set screw 43. As best illustrated in FIG. 4, the shoes provide contiguous Web supporting surfaces entirely around the peripheral portion of the roller.
  • the forwardly moving web contacts the roller at its lowermost portion, passes 180 therearound in contact with the shoes 36 and leaves at its topmost portion, and the bars 3637 are free to travel longitudinally with and thus accommodate lateral movement of the web during this passage.
  • two cam tracks 44 cooperating with the end portions 37 at the two ends of the roller are two cam tracks 44 disposed to contact the free ends of portions 37 during their idle travel'downwardly (FIG. 4) and thus centralize the shoes 36 longitudinally as they reach the web-engaging position.
  • portions 56 projecting from one end thereof and outwardly beyond the adjacent supporting flange 30 and each such portion carries a laminated soft iron core 58 therein.
  • a solenoid coil 68 surrounding each such portion and core is grounded to the flange 3.0 and .to a con- In. this case the web supporting bars have non-magnetic end tact 62 carried by the bar and spring pressed into engagement with a commutator strip 64.
  • the web enters and leaves the roller as indicated by the arrows in FIG. 7 and during the downward idle movement of the bars the contacts serve to energize the coils whereupon the cores are centralized therein and serve to centralize the Web supporting bars.
  • segmental bars 36-37 provide web supporting means on the roller 20 that travel both forwardly and laterally with the web, thereby accommodating the lateral shifting of the web during its helical passage about the roller and eliminating the webroller friction heretofore present.
  • the freely movable bars in effect provide a frictionless roller 20 whereby the Web delivered thereonto from its helical path about the roller 18 freely follows a true helical path about the roller 20, thereby eliminating any canting and wrinkling of the web as occurs when both rollers present frictional resistance to the lateral movement of the web.
  • either abutment 18' or 20 can employ the segmental roller embodied in our invention and except for the added expense involved, the use of our segmental roller for both abutments, as illustrated in FIG. 10, eliminates longitudinal and lateral friction in both abutments and provides substantially perfect helical frictionless tracking of the web about the abutments.
  • the segmental roller is shown at 65 and the plain roller at 66 and in FIG. 10 two segmental rollers 67 are employed.
  • FIGS. 11() While in the form of invention shown in FIGS. 11() We have mounted the web supporting bars 36-37 for free longitudinal movement on the roller 20 and have depended on the web for moving the bars longitudinally in the helical tracking of the web, our invention alsocontemplates a positive moving of the bars to accommodate the lateral shifting of the web and to guide it through the required helical path about the roller.
  • the machine shown in FIGS. 11-17 of the drawings for performing this function will now be described.
  • the web supporting abutments 68 and 70 shown in FIGS. ll'17 correspond to the abutments 18 and 20 shownin FIGS. 1-10 and comprise rollers rotatably mounted in a like frame including plates 72 rigidly supported on the ends of a bar 74 pivoted at 75 on an upright 76 rigidly supported on a plate 77 corresponding to the base 10.
  • the web supporting bars 78 are herein illustrated as cylindrical rods having reduced end portions 79 mounted to slide longitudinally through bushings in spaced'flanges 80 carried on an axle 82 mounted in hearing supports 84.
  • the web 12 is fed forwardly in a plane path P (FIG. 13) to and arcuately about the plain roller abutment 68, thence rearwardly to and arcuately about the segmented roller abutment 70 and thence forwardly in a plane path P parallel with the path P.
  • the web functions to move. the bars 3637 longitudinally therewith as the web travels helically about the roller 20
  • the mechanism shown in FIGS. 11'17 provides means for automatically moving the bars 78 longitudinally to con-' form to the lateral shifting movement of the web as the web travels in a helical path about the roller.
  • the mechanism for performing this function includes two flexible cam tracks in contact with the ends of the websupporting bars together with a novel system of levers for automatically flexing the cam tracks into helical form of varying degree pitch when flexed from the normal position by pivotal movement of the abutment supporting frame 72-74.
  • the two cam tracks comprise two flexible annuli 85 respectively in contact with the ends of the bars 78-79 at the two ends of the roller.
  • Each such annulus is anchored at its bottom portion to a bracket 86 extending inwardly from the adjacent bearing support 84.
  • Diametrically opposite thereto each annulus is split and its two ends hinged together on a pivot pin 88.
  • the ends of each such pin are supported in a yoke 89 on one end of a link 90 pivotally connected at 91 at its other end to a lever 92 pivoted at 93 to a bracket on the adjacent plate 72.
  • the other ends of the two levers 92 at the ends of the roller are pivotally connected at 94 to two links 95 in turn pivoted together on a fixed post at 96.
  • each cam track 85 When the frame 7274 is in the position shown in FIG. 11 the two cam tracks 85 are in two parallel planes and hold the web supporting bars 7879 centralized therebetween, each annulus 85 being anchored in such plane on its bracket 86. In such position each cam face is right angular to the rotary axis of the roller and each pin 88 is parallel to the face of its cam.
  • the distance C between the pivots 91 and 93 (-FIG. 14) is equal to 1rD/ 2 D being the diameter of the segmental roller.
  • the distance between pins 94 and 96 is equal to the distance between the pivots 75 and 93 and the distance between pivots 96 and 75 is equal to the distance between pivots 94 and 93, thereby forming a parallelogram with corners at 75, 93, 94 and 96.
  • one lever 92 pivots outwardly and the other inwardly and flexes the cam tracks equally and in opposite directions into helical configuration.
  • This configuration in each track forms a cam face helix extending from the fixed portion thereof at 86 to the hinged pivot 88 and from thence back to the anchor 86 and the pitch of the helix varies with the pivoted extent of the frame.
  • the 180 wrap of the web on the roller from point 97 to point 98 is a distance 1rD/2 which is equal to the distance between the pivot 93 and the axis of the roller. While we have herein illustrated the web as wrapped 180 about the rollers it should be understood that other degrees of wrap may be employed so long as the entering and exiting reaches P and P of the web are maintained parallel.
  • rollers 20 and 70 are adapted to serve other useful and important web guiding functions within the scope of our invention. For example, it may be desired to change the direction of travel of a web (as shown in FIG. 18) or to reverse the two faces of a web and our novel rollers are adapted to perform these and other like functions with facility and without causing wrinkling or otherwise disturbing the free and uninterrupted travel of the web.
  • the axis of the abutment When no guiding correction is required, the axis of the abutment is oriented normal to the desired path of the web and there is no lateral component of motion of the web in passing around the abutment.
  • the axis of the abutment When a guiding correction is required, the axis of the abutment is tilted about an axis perpendicular to the approaching web and the tension of the outgoing web pulls the oncoming web about the abutment in the shortest path, which is a helix, because friction force opposing the motion of the web acts parallel to and in the opposite direction to the relative motion of the web and the surface of the abutment.
  • the path of the web is a helix.
  • the pull of the outgoing web rotates the cylinder instead of sliding the web over it, thus tend ing to guide each lengthwise element of the in-coming web away from its desired path, and into a plane at right angles to the axis of the rotating cylinder and passing through the last previous point, which controlled the location of the element.
  • last previous point is the location of the element as it leaves the roll immediately before the rotating abutment mentioned above.
