Definitions

  • ABSTRACT The invention relates to an apparatus for closing the opening formed at or near the toe end of a circularly knit stocking which is knit from a yarn forming a stocking web, where a bead is provided along the edge of said opening.
  • the apparatus has a guiding channel with a longitudinal slot, through which channel the superposed bead halves are advanced from one end to the other, the stocking web extending through the slot of the channel.
  • a clamping device consisting of a stationary table and a rotating presser foot between which the stocking web is clamped so as to be advanced past a seaming station by the rotation of the presser foot.
  • the guiding channel is continued along part of the contour of the clamping device, but ends at some distance from the seaming station.
  • This invention relates to an apparatus for the closing ofthe toe of a circularly knit stocking which is knit with a thickened bead along the edge of an opening to be closed.
  • the toe portion is formed in the circular knitting machine by causing the knitting head to perform an oscillating movement instead of a progressively rotating movement.
  • the subsequent closing of the toe does not take place at the very tip of the toe, but along a so-ealled looper-line which extends across the upper side or underside of the stocking foot near the tip thereof.
  • Toe closing apparatus are known. e.g.. from US. Pat. No. 3,527.l8l. which are based on stocking blanks having such guiding beads and which are constructed with a pair of superposed jaws having marginal portions defining between them a guiding channel having a longitudinal slot, the channel being constructed to receive the superposed bead halves of a stocking. the stocking web extending through the slot of the channel, the superposed bead halves being pushed into the guiding channel at one end thereof and the stocking then being slid along the guiding channel and, upon leaving it at its other end. proceeding directly to a toe closing or seaming station e.g.. comprising a trimmer for cutting offexcess stocking web. followed by a sewing machine.
  • a toe closing or seaming station e.g.. comprising a trimmer for cutting offexcess stocking web. followed by a sewing machine.
  • an apparatus for the closing of the toe of a circularly knit stocking which is knit from yarn forming a stocking web with a thickened bead along the edge of an opening to be closed by means of the apparatus comprises, in combination, a stationary flat stocking toe support having a curved edge portion. a presser foot engageable with said stocking toe support to clamp the toe portion of a stocking between said presser foot and said support. said presser foot being rotatable and having a clamping edge substantially concentric with said curved edge portion of said stocking toe support at a small distance therefrom. toe closing means disposed at a seaming station adjacent said curved edge portion of said stocking toe support.
  • the stocking toe portion does not proceed directly from the guiding channel to the seaming station. but is taken over. before reaching that station. by a clamping device consisting of the stocking toe support and the presser foot and is therefore firmly held in a flattened condition along a contour defining the seaming line. the latter being formed immediately adjacent said contour as the stocking toe portion is moved past the seaming station by the rotation of the presser foot.
  • the continuation of the guiding channel along part of the contour of the clamping device ensures that the stocking web is transferred to the clamping device in a regular. nondistorted state with the courses of the stocking web extending along said contour.
  • the regularity of the stocking web being transferred from the guiding channel to the clamping device may sometimes be further improved by arranging the part of the guiding channel extending along the curved edge of the stocking toe support in such a manner as to diverge from the contour of the presser foot in a direction from said delivery point to said second free end so that the stocking web outside the contour of the presser foot is slightly stretched during part of its travel to the seaming station.
  • the axis of rotation of the presser foot is inclined with respect to the stocking toe support.
  • the clamping edge of said presser foot being formed by a toothed collar of resilient material. This is one way of facilitating the introduction of the stocking web between the stocking toe support and the presser foot.
  • the stocking toe support has a rear termination located at the point of delivery. an inclined guiding lip being provided at that location for guiding the stocking web from below on to the top surface of the stocking toe support to be gripped by the presser foot rotating thereabove. This is another way of facilitating the introduction of the stocking web between the stocking toe support and the presser foot.
  • a further guiding lip may be provided rearwardly of the stocking toe support in a position such that the stocking web is guided below said further guiding lip before proceeding to said inclined guiding lip. The stocking web is thereby protected against untimely engagement by the presser foot before it reaches the point of deliver.
  • FIG. I is a first embodiment of the apparatus according to the invention. in top view.
  • FIG. 2 on a larger scale. is the zone FIG. I indicated by B in that FIG. with diagrammatic illustration of the courses of a stocking being advanced towards the position in which seaming is to take place.
  • FIG. 3 is a section along line Ill-Ill of FIG. 1.
  • FIG. 4 on a larger scale is the zone of FIG. 3 indicated by A in that FIG.
  • FIG. 5 is a section along line V-V of FIG. 1.
  • FIG. 6 is diagrammatically a second embodiment in perspective view.
  • FIG. 7 a section along the broken and partly curved line VllVll of FIG. 8.
  • FIG. 8 is a top view of the second embodiment, the presser foot being indicated by a contour line, and all parts above it being removed.
  • l is a stationary table or stocking toe support and 2 is a circular presser foot engageable with the table to clamp the toe portion of a stocking therebetween.
  • the table 1 has a circular portion la substantially concentric with the presser foot 2 and a rectilinear portion lb
  • the presser foot is mounted on a shaft 3 which is slightly inclined from the vertical and which is rotatably driven by a driving motor, not shown.
  • the presser foot has a collar 4 of resilient material such as rubber, which is of a conical configuration having teeth of serrations along its lower edge which engages the table 1 along its circular portion starting approximately in the position indicated by 5, hereinafter referred to as the delivery position, and moves along the edge of the table 1 past a seaming device 6 which is located immediately outside the edge of the table in a position spaced about 90 from the delivery position 5.
  • the seaming device may in known manner comprise a trimmer to cut off the superposed bead halves, and sewing needles, but no fabric feeding means of its own.
  • the apparatus further comprises a pair of guiding jaws 7 forming a longitudinally slotted guiding channel to receive the superposed bead halves B of a stocking S, see FIG. 4, the slot between the jaws being denoted by 7a.
  • the guiding jaws have a freely disposed feeding portion 8 extending to the edge of the table 1 in the delivery position from which the guiding jaws continue without interruption in a path extending along the edge of the table 1 and slightly diverging from the lower edge of the presser foot until a point slightly ahead of the position of the seaming device 6.
  • the table 1 is provided with a recess 10.
  • the superposed bead halves of a stocking is in known manner pushed into the guiding channel formed between the guiding jaws 7, FIG. 4, and the stocking is then manually slid along the guiding channel until it reaches the position 5.
  • these may be provided with slightly bend end portions 11.
  • an elastic guiding lip 12 may be provided to keep the stocking web down level with the upper surface of the table 1. The stocking is now automatically advanced along the edge of the table 1.
  • the table or stocking toe support 1 has approximately the same configuration as in the first embodiment. It will be seen particularly clearly from FIG. 8 that the table 1 has a rear termination at the delivery position 5, and from there the edge of the portion 1a of the table extends along a circular arc to position 6, like the edge of table I in the first embodiment. From position 6, the portion lb of the table extends substantially tangentially with respect to the lower edge of the presser foot. Like in the first embodiment, the guiding jaws diverge slightly from the contour of the presser foot from position 5 to their exit end, though this is not essential. The recess 10 has been omitted.
  • the shaft 30 of the presser foot 2 is disposed perpendicularly to the plane of the table 1.
  • the presser foot has a resilient collar 40, that may or may not be toothed or serrated along its edge.
  • a downwardly sloping guiding lip 21 is provided at the rear termination of the support I to guide the stocking web extending through the slot between the guiding jaws 7 from below onto the upper surface of the table 1.
  • a further guiding lip 12a is provided to keep the stocking web out of engagement with the presser foot until the time when it arrives position 5.
  • the lip 12a is preferably rigid, and its upper surface is level with that of the support 1 so as to form a support for the edge of the presser foot 4 in its approach to the table 1.
  • a belt drive 22 is provided for automatically advancing the stocking along the guiding channel formed between the jaws 7.
  • the belt drive 22 and the presser foot are synchronously driven linearly from an electric motor, not shown, through a transmission diagrammatically represented by gear wheels 24, 25, 26 and 27.
  • the electric motor is started by a microswitch 28 when the frontmost end of the superposed bead halves has been advanced by hand to the location of that micro-switch.
  • the seaming device at position 6 is started by another micro-switch 29 when the frontmost end of the superposed bead halves arrives at the location of that microswitch.
  • the clamping device consisting of the table or stocking toe support and the presser foot may be constructed similarly as described in British Pat. specification No. 1,201,829 the table having a smooth surface and the presser foot being constructed to engage the stocking frictionally.
