Linear knitting machine

Abstract

A linear knitting machine ( 1 ) comprising a loom, at least one needlebed ( 3 ) associated with the loom, a plurality of needles ( 4 ) sliding in the needlebed ( 3 ), means for feeding the needles ( 4 ) with a yarn for building a new stitch and knock-over means ( 8 ) cooperating with said needles ( 4 ) on the needlebed ( 3 ) and moving between a forward position, which occurs when the needle ( 4 ) is lifted, in which they act upon said stitch so as to keep it on the stem ( 5 ) of the needle ( 4 ), and a rear position, when the needle ( 4 ) gets down, in which they do not act upon the stitch. The machine ( 1 ) is characterized in that it further comprises holding means ( 15 ) fastened to the loom and discharging means ( 19 ), associated with the knock-over means ( 8 ), which can be engaged with said holding means ( 15 ) in forward position for discharging onto the loom the force generated by the knock-over means ( 8 ) when keeping the stitch, and which can be disengaged from the holding means ( 15 ) in rear position.

Description

technical field [0001] The present invention relates to Raschel flat knitting machines, which are generally also called Raschel warp knitting machines and are used for the manufacture of any type of textile. Background technique [0002] A particular feature of known warp knitting machines is that the fabric just formed is drawn downwards by suitable dropping devices, so that the old loops do not rise due to friction with the needles that will acquire new yarn, but remain in a lowered position to successively emerge from the The needles are removed and there is room on the needle shaft for the new loop just formed. Also, due to the drop action, when the needles move downwards, the loops attached to the needles are able to rotate the latches to close the jacks carrying the new yarn, making it possible to unload the old knitting loops and Form a new loop (in the case of a latch needle). [0003] Known take down devices comprise at least two rollers exerting a force against t...

AI Technical Summary

Problems solved by technology

However, operating speeds are still low due to inertial forces due to the large masses involved

Thus, in addition to the disadvantage in manufacturing costs, there is also a disadvantage with regard to the final operating speed of the machine

[0013] In order not to place too much burden on the structure of the holding element bed carrying the holding elements, the drop system is modified so that the pressure and rotational speed between its rollers reaches the fabric acceptable limits, which are known to result in hazards including fracture or permanent deformation
