Definitions

  • ABSTRACT A process for manufacture of stocking heel pouches includes (g1 "66/336 the use of a circular knitting machine cylinder with a row of needles and a row of submeedles overlying one another and [58] Field of Search ..66/48, 51, 47, 43, 3-9, 187 butts and control cams which are arranged in arcs which are l 56] References Cited staggered with respect to one another The extent of the arcs can be varied. A group of stitch courses in one direction is n- STATES PATENTS reversed in the next group of courses.
  • This invention relates to a process for the formation of a pouch in a tubular knit fabric (such as a stocking heel or the like) working with at least two yarn feeds, and with an alternating motion of the needle cylinder of the circular knitting machine.
  • a circular knitting machine for knitting pouches in knit fabric comprising at least two yarn feed means, a needle cylinder having longitudinal grooves therein and including needles, sub-needles, control cams, needle-raising control butts on each sub-needle disposed in the working zone of the pouch, said butts being arranged in rows equal in number to the number of yarn feed means, and arranged in partially staggered arcs substantially symmetrically with respect to an intermediate zone in which the butts of all rows of butts are present, said cam means acting on the butts to raise the needles, means to render the needles inoperative by lifting the needles externally of the working zone of the machine, and means to modify the working amplitude of the working zone of the machine including an exclusion device and an inclusion device effective on end needles of the arcs.
  • FIGS. 3 and 4 illustrate the operational mode of the cams of FIG. 1 during the motion in opposite directions of the needle cylinder respectively;
  • FIGS. 5 and 6 illustrate the shaping of fabric in the pouch zone respectively in a diagrammatic arrangement and in an illustration similar to the actual shape
  • the cams 23, 25, 27, 29 cause the initial lowering of the butts 17A, which butts are subsequently fully lowered by the cams 1 to 7.
  • a cam 31 acts on the long butts 17A to exclude the corresponding needles from the work by raising, the raised needles retaining the stitches last formed thereby.
  • a cam 33 acts on the long butts 17A to re-insert the corresponding needles into work by lowering thereof.
  • the cams 31, 33 operate with the cylinder motion in the direction of arrow f,.
  • the butts 17B extend over a portion of the working are ,8 and are spaced from one end thereof.
  • the butts 17C extend over another portion of the working arc B, and are spaced from the other end thereof. While the butts 17A operate with the cams 1, 3, 5, 7, 9, 11, 13, 15, 23, 25, 27, 29, 31 and 33, the butts 17B and 17C cooperate with pairs of cams 35, 37 and 39, 41 respectively.
  • the operation of cams 35, 37, 39, and 41 is well known, as, for example, shown in Italian Pat. No. 655,21 1 and hence the conventional cam operation will not be described herein in order not to obscure the invention.
  • the working arc B is divided into three zones, [3, central and fl B lateral.
  • the central zone [3, the number of stitch courses is double that in the outer zones 3,, B In these zones 13,, [3 the stitch courses have symmetrical increases and reductions.
  • the central are 5, corresponds to the zone wherein the butts 17B and 17C are simultaneously located in the sub-needles 19, while the zones 5, and B correspond to the arcs whereinonly butts 178 or 17C are located, the butts of the outer ends of said arcs being excluded and reinserted in operation.
  • pairs of lowering earns 73, ,75; 77, 79; 81, 83 arranged at three different levels to cooperate with butts 85B, 85C, 85D of a sub-needle 85 engaged to each needle 87 and provided with a first but 85A cooperating with the raising and lowering cams 61, 63, 65, 67, 69, 71.
  • the pairs of lowering cams 73, 75; 77, 79; 81, 83 act on groups of butts 85B, 85C, 85D which are staggered.
  • FIGS. 8 to 11 allows the forming of a heel pouch by means of three feeds or supplies AF, AF,,, AF, and with the aid of the cams 73, 85, 77, 79, 81, 83.
  • 15 courses of stitches are formed along the are L,, while along the adjacent and symmetrical arcs L, l 1 courses of stitches are formed and along the symmetrical arcs L only 7 courses of stitches are formed.
  • the arcs L are narrowed by the variation of the ends 855,, and 85D, while the outer ends of the arcs L and the end of the arc L are kept constant for the constancy of the end butts in the ends 85C,, and 85C and in the ends 85D and 85B respectively.
  • the latter may always be widened with the picker arrangement.
  • the yarn of feeds AFS and AF7 are fed to and knit by different arcs of needles to form overlapping part courses.
  • the yarn of feed AF6 is fed to and knit by an arc of needles to form a part course which includes in coursewise extent the overlap of the first two part courses (L1).
  • the ends of the part courses formed at feed AF 6 are walewise aligned and define a middle zone of the pouch.
  • each part course formed at feed AF5 or AF7 extends over a substantial portion of the middle zone.
  • the outer ends of the part courses knit at feeds AF5 and AF7 are narrowed for a number of strokes of reciprocation to provide an edge at each side of the pouch. Subsequently the outer ends of these part courses are widened for a number of strokes of reciprocation to continue each pouch edge. Each edge is in effect joined to itself as widening occurs to provide the usual suture.
  • the ends of the part courses knit at AF5 and AF7 which appear within the middle zone are walewise aligned on each side of the zone.
  • FIGS. 12 to 15 are operational diagrams relating to a machine including eight yarn feeds and thus eight fall cams corresponding to the four feeds AF AF AF AF, provided for forming of a heel pouch with the cooperation of lowering cams 91, 92, and 97, cooperating with butts respectively 99B, 99C, 99D, and 99E of a sub-needle 99 also provided with butts 99A and coupled with the corresponding needle 101.
  • the operation is similar to that of the previous embodiments as provision is made for insertion into the working position during the heel forming of the needles of an are E, which is variable for the insertion and disengagement of the needles by means of the so-called picker arrangement.
  • a central arc M of the pouch may have, for example, 20courses of stitches, while two arcsM- have 15 courses of stitches, the adjacent arcs M 10 coursesand the arcs M only 5 courses of stitches.
  • the end arcs M have a variable amplitude.
  • said exclusion device includes a row of butts some of which are long butts effective to exclude initially needles along an are from the work, said butts also serving to restrict the working zone, and picker members capable of excluding and including the needles of the needle cylinder.
  • a process of forming a pouch with an edge at each side in a tubular knit fabric on a circular knitting machine having at least three feeds and having a circle of needles mounted in a needle cylinder capable of reciprocatory motion comprising the steps of, feeding and knitting a first yarn from a first feed on a first arc of needles during a first stroke of reciprocation to form a first part course, feeding and knitting a second yarn from a second feed on a second arc of needles during said first stroke of reciprocation to form a second part course, feeding and knitting a third yarn from a third feed on a third are of needles during said first stroke of reciprocation to form a third part course, the first and second ends of the said second part course defining a middle zone of said pouch, said middle zone being spaced inwardly of both pouch edges, said first part course extending from one end within the middle zone over a substantial portion of said middle zone to the other end at one edge of said pouch, said third part course extending from one end within the middle zone over a substantial portion of
