Definitions

  • the present invention relates to a new system for stretching knitted fabrics on straight knitting machines which presents a significant technological progress compared to conventional systems.
  • GB-A-1 243 661 describes a knitting system comprising in particular a plate against which an endless band is wedged, said band being mounted between a roller and another plate and sliding on the upper edge of said other plate, so as to obtain a pinch effect for knitting.
  • the subject of the present invention is a system as characterized in claim 1.
  • the difficulty which the systems of the prior art provide is resolved in a completely satisfactory manner by ensuring a regular stretching of the knitted fabric whatever the shape of the knitted panels and their dimensional variation.
  • the stretching of the knitted panels is kept regular even if their thickness also varies.
  • the recommended improvements are based on the transmission to the panels or parts of a pinching effect with positive drive, so that the rate and the extent of this drive coincide with the rate of the operational cycles of the machine and with the extent of knitting obtained during each cycle.
  • a main roller (1) motor or drive receiving the movement with the collaboration of a ratchet wheel (2), which in turn receives a movement of an eccentric or else by means of '' an individual motor, not shown in the figure, regulating the advance of said main roller (1) by a positive movement, at a rate and extent consistent with each working cycle of the machine during the making of knitted pieces (3-4 ).
  • the main roller (1) which rotates in the direction of the arrow shown in Figure 1, transmits a traction or positive drive of the knitting down through the collaboration of a series of rubber bands (5), which are four in number in the embodiment shown, extending between said main roller (1) and the corresponding stretching rollers (6) of reduced diameter, located coaxially at the outlet of the set of needles between the two needle beds of the machine.
  • the arrangement of the rollers (1 and 6) determines for the rubber bands (5) a straight and descending plane which coincides with the mean vertical plane of the machine and adapts to each of the lateral faces of the knitted pieces (3-4) by pressing said parts against an oscillating plate (7).
  • the rubber bands (5) must be perfectly tensioned to fulfill their function of pinching against the oscillating plate (7) and driving the knitted pieces, with the collaboration of tension rollers (8) assisted by springs (9) regulating the unfolding of these bands.
  • FIG. 1 in dotted lines and under reference (10), a set of pressure rollers has been shown corresponding to a conventional stretching system, to highlight the total conceptual and structural disparity of the two systems, as well as the fact of whether or not the installation of such conventional balls (10) has no conventional influence on the stretching system proposed by the invention.
  • the invention is in no way limited to the embodiment of the example described and shown, it is capable of numerous variants accessible to those skilled in the art, depending on the applications envisaged and without departing from it. of the scope of the invention.
