Definitions

  • the second roller has a wider groove than the groove of the first roller adapted to the curvature of the needle and the thickness of the goods.
  • Vibration means are provided to vibrate the rollers in a direction substantially parallel to the longitudinal axis of the needles and the rollers are axially shiftable on their axles.
  • the present invention relates to a device for the mechanical impaling of weft-knitted and warp-knitted goods on needles of circular looping machines.
  • The. device acts by means of a roller having a peripheral groove gripping around the needles on the goods to be impaled.
  • Such devices can accomplish their task only in the case of light goods such as stockings, but not in the case of of heavy and fine-meshed goods which have a considerable resistance against the shifting down on the needle shaft.
  • the shifting down is then possible only under strong pressure and multiple to-and-fro movements of the work supporting needles orthe impaling device, therefore, there is no longer any advantage when compared with impaling by hand.
  • Fine mesh flexible pieces of goods such as those of synthetic fiber or those lined with taffeta tend to tilt on the extremities of the needles and to clamp between the roller or its grooved wall and the needles.
  • this result is produced by arranging a further roller behind a freely movable roller which is in front in working direction.
  • Each of the rollers has a peripheral groove gripping on two sides around the needles.
  • the depth of action of the front roller is smaller than that of the following roller and the first roller narrowly encloses the extremities of the work supporting needles.
  • the rear roller has a larger width to its groove and is adapted to the curvature of the needles and the thickness of the material respectively.
  • Means are additionally provided which is utilized to subnrit the two rollers to rapid vibration of high frequency in their direction of action.
  • the two rollers are arranges so that they are actually axially shiftable on their respective axles and furthermore the outer rim of the disc-shaped lateral limits of the groove of each roller is chamfered toward the interior.
  • the rollers may be interchangeable so that rollers with a width and depth of the groove can be selected according to the goods to be impaled.
  • a holder may also be provided on the impaling device.
  • There is supplementary means which may be fastened on the holder such as edge pressing rollers, edge rules, optical enlargement devices or lighting fixtures.
  • the rapid vibration of the cited pair of rollers can be generated by a magnet oscillator.
  • the impaling device may be guided on an arm pivoting around the middle column of the looping machine. This arm would be utilized for elastically pressing the impaling device against the pieces of goods to be impaled.
  • means may be provided which allow the device to be swung away to and from a working position and its blocking in whichever respective position desired.
  • the apparatus'provided by this invention embodies a device for the mechanical impaling of weftknitted and wrap-knitted goods on needles of knitgoods machines.
  • the apparatus basically includes a first and second roller with each roller having a peripheral groove gripping around the needles.
  • the first and second rollers are adapted to act on the goods to be impaled and are arranged so as to have their grooves embracing the needles consecutively with the first roller leading the second roller in the working direction.
  • the first roller has a groove of less depth than the groove of the second roller to narrowly grip the extremity of each needle.
  • a second roller has a wider groovethan the groove of the first roller and is adapted to the curvature of the needle and the thickness of the goods.
  • Vibration means are provided to vibrate the rollers in a direction substantially parallel to the longitudinal axis of the needle and the rollers are axially shiftable on their respective axles.
  • FIG. 1 is a front elevation view of the apparatus of the invention in operational position with respect to a looping machine shown by means of a sectional view through a work supporting needle plate thereof;
  • FIG. 2 is a plan view of the apparatus of the invention shown mounted on the work supporting needle plate of a looping machine and depicted in the direction A as indicated in FIG. 1;
  • FIG. 3 is an enlarged partial front elevation view of the apparatus of the invention showing a detail of the front roller
  • FIG. 4 is an enlarged fragmentary front elevation view of the apparatus of the invention showing the rear roller portion thereof.
  • rollers 3 and 4 which act on fabric 2 to be impaled on the work supporting needles, are rotatable on the pivot pin and can be axially shifted.
  • Pivot pins Sare rigidly mounted on roller holder 6 which itself is rigidly connected with the swinging axle configured as an extended rocking shaft of a magnet oscillator or vibrator enclosed in casing 8.
  • roller 3 which is in front in working direction, is of a smaller diameter than rear roller 4. Both rollers 3 and 4 have a peripheral groove 9 and 10 respectively (preferably wide and deep as shown) by means of which they embrace the work supporting needles 1 of machine 40 from top and bottom in the relationship as shown in the drawings. Groove 9 of the front roller 3 is less deep and less wide than groove 10 of the rear roller 4 so that groove 9 grips around only the cylindrical part of the needles, while groove 10 can embrace the needles down to the necessary impaling depth as shown particularly in FIGS. 3 and 4.
  • the respective outer rims 11 and 12 of the disc-shaped lateral walls of grooves 9 and 10 are chamfered toward the interior.
  • Casing 8 of the magnet oscillator is fastened on an arm 13 which can be pivoted around an axle 14. This arm may be held elastically in the desired position by means of the lever 16 penetrating into the slotted disc 15.
  • Axle 14 is arranged on a bracket fastened pivotally on the middle column of the looping machine, but which is not shown in detail in the drawings.
  • the housing or casing 8 of the swing magnet or oscillator 20 is mounted on an arm 13 capable of swinging on a pivot 14.
  • a pivot or axle 14 is mounted on a bracket arm fixed to the leg of the machine.
  • the levers 16 which are pivotted on the bearing 23 provided on the bracket arm 21 are held by spring action against the disc attached to arm 13 and lying in its plane of swing, while engaging rests 25 on the circumference of the disc by rollers 24.
  • supplementary devices 18 may be fastened such as edge pressing rollers, edge rules, oralso opticalenlargement and illumination fixtures.
  • connection piece 19 may be provided in which the outer extremity of the extended shaft 7 is journaled.
  • the impaling device embraces the work supporting needles from below, the pivot pins 5 are directed upward so that rollers 3 and 4 can be put on loosely from above and can be interchanged easily with others having different grooves -9 and 10 with respective widths and depths adapted for use with the particular goods to be impaled and the particular shape of the needles being utilized.
  • rollers 3 and 4 When the impalingdevice is swung in or blocked, respectively, in its work position, rollers 3 and 4 are lifted by the gliding of their respective chamfered outer rims 11 and 12 on the extremities of the work supporting needles in an adjustment corresponding to the curvature of the work supporting needles 1 and theform of these needles as shown in FIGS. 3 and 4.
  • the fabric being guided possibly with edge rolling devices 18 under the front roller 3, is shifted by this roller first on the extremities of the needles and then is shifted by rear roller 4 on the needle shaft down to the desired depth. Because of the rapid vibrations of rollers 3 and 4, which is essentially in a direction toward the needles and which is is generated by the magnet oscillator provided in casing 8, this impaling process is carried out.
  • Narrow groove 9 of front roller 3 grips only around the extremities of the needles and its smaller penetration depth prevents the danger that the fabrics 2 might tilt and get wedged between the needles and the lateral walls of the grooves.
  • This apparatus is not limited alone to looping machines of round and flat construction, but it can be used just as advantageously for the transfer combs of straight knitters. For special and exceptional cases, it may also be suitable to use the apparatus of this invention as a hand device.
  • Apparatus including vibration means for the mechanical impaling of weft-knitted and warp-knitted goods on needles of knit-goods machines such as a looping machine comprising:
  • each of said needles having a longitudinal axis
  • each roller having a peripheral groove embracing the needles
  • each roller being mounted on an axle on the ap paratus
  • rollers being vibrated by the vibration means in a direction substantially parallel to the longitudinal axis of the needle embraced thereby;
  • said first and second rollers adapted to transfer the vibration caused by said vibration means to the goods to be impaled; said rollers arranged so as to have their grooves embracing the needles consecutively with the first roller leading said second roller;
  • said first roller having a groove of less depth than the groove of the second roller to narrowly embrace the extremity of each needle
  • said second roller having a wider groove than the groove of the first roller adapted to any predetermined curvature of a needle and the thickness of the goods;
  • rollers being axially shiftable on their axles.
  • each roller has a pair of substantially parallel discshaped lateral walls, a portion of said walls defining the side walls of said groove, and the outer edge portions of the rollers are adapted to be removably mountedon their axles.
