Definitions

  • the present invention relates to a circular knitting loom, single needle, with pallet needles or needle-nosed, loom which in the following description will be designated by 1: 'expression "jersey loom”.
  • the knitting members proper are mounted and controlled as shown schematically in Figure 1.
  • the rotary cylinder 1 carrying the needles 2 is mounted on a circular plate, integral with the frame 3 , and is driven by means of drive gears not shown in this figure.
  • the movements of the needles 2 are obtained by means of cams 4 mounted on a fixed support 5.
  • a divided plate b (circle) carrying the plates 7 is secured to the cylinder 1 by means of flanges 8 and is therefore driven in synchronism with the latter.
  • the movements of the plates 7 between the needles, in synchronism with the movements of the latter, are obtained by means of fixed cams 9.
  • These cams 9 are also carried by a crown 10 secured to the frame of the loom 3 by means of columns 11.
  • the jersey knitting machines with beak needles include individual pressers, movable in synchronism with the needles and the platinets, intended to close the beak of the needles at the appropriate time during the formation of knitting.
  • the Applicant proposed in its French patent application No. 79/12 531, filed on May 11, 1979, a jersey needle-nosed loom, of simple design, in which the pressers are mounted on a divided circle carrying the platinettes and are guided laterally by them.
  • patent of the United States of America n ° -2 069 155 describes a solution according to which the drive in rotation of the plates is obtained by providing at the periphery of the crown supporting these plates a toothed sector which comes mesh with the divisions provided in the cylinder.
  • Figure 2 schematically illustrates in section the main organs of a jersey loom with pallet needles.
  • This loom consists essentially of a conventional frame 3 supporting a divided cylinder 1 rotating intended to guide and hold the needles 2.
  • This cylinder 1 is driven in rotation by means of pinions connected to a motor (elements not shown).
  • platinettes 7 the mounting and control of which, in accordance with the invention, will be seen in more detail in the following description, contribute in combination with les.aiguilles 2, to the formation of the meshes.
  • Such a loom includes a plurality of knitting scraps, each drop being fitted with cams 4 making it possible to form a row of stitches.
  • Each fall also includes means (guides 26) for distributing the wire 27 to the needles 2, this wire coming from a support generally arranged above the loom.
  • the knitted fabric 12 is pulled and wound in a conventional manner by means of elements driven in rotation in synchronism with the rotary cylinder 1.
  • a divided circle 6 is placed facing the needles and carries the plates 7 movable between the needles under the action of cams 9.
  • the circle 6 is mounted on a fixed ring 20 which serves as a guide and positioning element.
  • This ring is secured to the frame by means of columns 11, distributed over the periphery of the loom.
  • the crown 20 comprises a continuous raised part 21, a complementary hollow part 22 being provided in the base of the circle 6.
  • the raised part 21 can optionally serve as a guide rail, but essentially has the function of playing the role of '' a baffle allowing on the one hand, to retain the lubricating oil, and on the other hand, to prevent the fluff and fill from entering the sliding path.
  • the rotation drive of the circle 6 carrying the plates 7 is obtained in accordance with the invention directly by action of the cylinder on the plates and without any connection, such as for example fixing lugs, with the cylinder 1 or use of means d 'training additional.
  • This drive is communicated directly by the plates 7 which are guided in grooves provided in the circle as well as in corresponding grooves 31, formed in the upper part of the cylinder 1 (see FIG. 4).
  • the plates 7, during the rotation of the cylinder 1, therefore also drive the circle 6.
  • the circle of plates is made of treated steel and the support 20 is made of cast iron.
  • lubrication is ensured by the overflow of lubricating oil for the beds, oil which can be recovered in part by means of small reservoirs arranged under the plate (elements not shown in the appended figures).
  • FIG. 3 illustrates an embodiment in accordance with the invention for a jersey needle needle loom of the type described in French patent application No. 2 79/12531.
  • the drive in accordance with the invention also has the consequence of giving self-centering of the divided circle carrying the plates.
