Definitions

  • the present invention relates to a machine for folding strip-shaped textile material, particularly stockings.
  • An object of the present invention is to provide a machine for the above purpose which is of simple and inexpensive construction and which can be operated economically.
  • the new machine comprises a folding fork which is held turnably about a horizontal axis in a supporting structure, there being further provided a conveyor for feeding strip-shaped fabric material, such as pairs of stockings, inbetween the tines of the fork, and a drive by means of which the fork can be rotated for folding the fabric to a width equivalent to the width of the fork.
  • a special and additional advantage of such machines is that their construction permits the operations to be performed manually, semi-automatically or fully automatically. For this reason the new machines may be used in the smallest as well as in the largest manufacturing plants.
  • FIG. 1 is a schematical representation of the described machine and its accessories, the drawing being a plan view;
  • FIG. 2 is a practical embodiment of the folding arrangement, shown in an elevation
  • FIG. 3 is a plan view of the arrangement illustrated in FIG. 2;
  • FIG. 4 illustrates the use of an adjustable fork
  • FIG. 5 illustrates the use of a plurality of differentsize, interchangeable forks.
  • the machine shown in FIG. 1 is provided with a transport table 1 in the form of a four-sided plate which is swingable about a vertical pivotable mounting axis 2 be- "ice tween two extreme positions 1 and 1".
  • a transport table 1 in the form of a four-sided plate which is swingable about a vertical pivotable mounting axis 2 be- "ice tween two extreme positions 1 and 1".
  • One of the longer edges of plate 1 i.e. the edge which faces the turning axis of the table
  • the folding equipment 6 In position 1, the folding equipment 6 is in register with the said cutout; and in position 1" (which is swung through as againstthe first-mentioned position), it is disposed adjacent to, with one of the shorter edges of the table plate being opposite, a conveyor means, e.g., a conveyor band 3.
  • the folding equipment 6 comprises a flat folding fork 7 which comprises two tines 8 (the number of tines may be more, e.g. three tines), which fork may be connected fixedly or change ably with a shaft 9 rotatably journalled in a supporting structure 22 of the machine.
  • the fork is positioned between two symetrically disposed spade-shaped jaws 10 from which jaws there extend, in the vicinity of shaft 9, outwardly directed lugs 11.
  • Each of these jaws is connected with the lug to one of two levers 12 at one end of the latter.
  • the opposite ends of levers 12 are hingedly connected with one of two brackets 13, these brackets extending from a sleeve 14 which sleeve is slidable on shaft 9. Both levers 12 are biased for opposite movement, i.e. towards each other, by means of a spring 15 extending between the levers and attached thereto.
  • the two jaws 10 are also spring-biased since, at each of the ends thereof which extends beyond the lugs 11 (at 18), there is provided tension spring 17 affixed at 16 to the outwardly extending ends of extensions of levers 12.
  • This construction permits the jaws to be positioned parallel to one another and to apply themselves to the fork at different distances between themselves and between the jaws and the fork.
  • Spring 15 pulls both levers 12 toward each other against forces generated at the instant or turning the fork, which forces act periodically, causing the jaws to move the maximum distance from one another, according to the Width of the folding fork.
  • the two jaws which can be swung about a pivot point 19 and which act as two-armed levers, are pressed springily against the folding fork 7, whereby uniform pressure on the fork is provided even if the latter is tapered.
  • the jaws 10 could be guided in parallel in another way, say by double-levers or the like.
  • Acting on sleeve 14 is a connecting rod 20 which is connected to a pedal 21 arranged in the machine structure 22.
  • Sleeve 14, and therewith the two jaws 10 can be moved axially on shaft 9 by operating the pedal and thereby can be withdrawn from the fork.
  • jaws might be withdrawn from the fork in another manner, say by swinging them or folding them upwardly or the like.
  • the drive of the machine is provided by a motor 23 which can be switched on or off by means of a switch 24 and which drives shaft 9 by means of a chain drive, V- belt, or gear wheels.
  • the drive is controlled in such a way that the folding fork is put into rotation during a certain period of time and at the end of that period is always in horizontal position.
  • the fork 9 should be turned into its vertical position (i.e., a turn through 90) so that the plate of the table could pass between the two tines.
  • a ratchet wheel 25 which can be turned by a ratchet 26 and a rod 27 by operating the pedal 28.
  • a supply roller 29 Co-ordinated with table 1 is a supply roller 29, the latter may be fitted with a photo-cell (not shown) or the like to rotate roller 29 whenever a ray of light directed against the photo-cell is interrupted by a piece of textile material.
  • Supply roller 29 is preceded by a roller 30 from which a packing foil can be reeled oif.
  • the machine described functions as follows:
  • the pair of stockings (or other fabric) is conveyed via the feeding means 3 onto the table 1 which is now in position 1".
  • the position of the stockings is adjusted, and the table is swung into position 1.
  • the pair of stockings lies across the cutout 5 of the table, between the tines 8 of the fork 7.
  • the motor 23 is now switched on, and the drive via the shaft 9 starts to rotate the fork, the speed of rotation being either constant or variable.
  • the fork rotates as long as it takes to wind thereon the stockings.
  • the two jaws 10 apply a tension to the stockings while they are rotated onto the fork, thus attaining a firm and tensioned wind or fold of the stockings.
  • the width of the folded stockings is in accordance with the width of the folding fork, which can be varied by using different-size, interchangeable forks (e.g., 208 208", FIG. 5), or by using forks with an adjustable width (e.g. fork 108, FIG. 4, made adjustable by fastener 110 seated in an elongated slot 112 in one tine and passing through an opening in the other tine), so that the width of the final package of stockings can be adjusted to a desired dimension.
  • an adjustable width e.g. fork 108, FIG. 4, made adjustable by fastener 110 seated in an elongated slot 112 in one tine and passing through an opening in the other tine
  • the fork is in horizontal position. In this position the distance between the two jaws 10 is equal to double the width of the wound-on layers plus the thickness of the fork, and the inner sides of the jaws apply themselves directly onto the wound material. Under the circumstances the removal of the wound material occurs against the pressure (which, although small, is still present) of the jaws against the fork. Sometimes this would be undesirable should the product be of delicate nature and easily damaged. However, such a likelihood can easily be met.
  • the diameter of the fork shaft is dimensioned in the vicinity or in the range of the junction between the shaft and the tines in such a way, say conically, that the contact areas of the jaws when the fork is positioned horizontallycontact the shaft and not the wound material.
  • the final position of the jaws in relation to the fork should be appropriately fixed.
  • the jaws 10 are removed from the range of the fork by operating pedal 21.
  • the table is then swung from its position 1' into position 1" in which the wound-on pair of stockings can be removed in several ways.
  • One way would be that the pair of stockings, after having pushed back the jaws, are removed from the fork 7 by hand or automatically, and conveyed to the roller 29, which latter conveys the pair of stockings via the conveyor 30 to a welding machine which welds together two layers of foil of plastic material wound off a roller 31, with the interposition of a pair of stockings, sealing the edges of the foil on the pair of stockings thus preparing a fully closed package.
  • a folding machine for strip-shaped textile material such as stockings, characterized in that it comprises a folding fork having a pair of spaced tines and rotatable about a horizontal axis, a drive for rotating said fork, a table formed with a cutout, feed means for feeding the strip-shaped textile material to said table, and a pivotable mounting for said table enabling same to swing about a vertical axis from a first position wherein it is disposed adjacent to said feed means for receiving the textile material fed thereby, to a second position wherein said fork is disposed within the table cutout and in position to fold the textile material carried by the table.
  • a machine as claimed in claim 2 further characterized in that said two jaws are slidable on said fork shaft.
  • a machine as claimed in claim 2 further characterized in that said drive is adapted to stop the rotation of the fork in a horizontal position after the conclusion of the folding, and further in that there is included a ratchet wheel for turning said fork through 90 to a position where new material can be introduced.
  • a machine as claimed in claim 2 further characterized in that there is provided a sleeve turnable on the shaft of the fork, and two oppositely disposed levers, one end of each of said sleeve being hingedly connected with said levers, said levers being urged toward one another by a spring, each lever being hingedly connected with one of said two spade-shaped jaws.
