Method for yarn feeding after the exchange of warp beam for a warp knitting machine and Warp knitting machine having a function for yarn feeding after the exchange of warp beam

摘要

The present invention is guided through holes 9 of guide needles fixed to the guide rod of the warp knitting machine 1 for thread insertion after replacing the warp beam in the warp knitting machine 1, and withdrawing the fabric from the warp knitting machine 1 connecting the old warp that forms the knitted fabric drawn into the device 3 with the replacement warp belonging to the warp beam newly replaced in this warp knitting machine 1; so that the replacement warp is actively released by the warp beam during the thread drawing-in step of the replacement warp, in which the warp thread thread the replacement warp into the holes 9 of the guide needles 8, and the thread drawing in of the replacement warp It relates to a method comprising the step of rotating a warp beam by using a warp beam driving unit of the warp knitting machine (1). In addition, the present invention relates to a warp knitting machine (1) having a function for drawing in yarn after replacing the warp beam, and including a fabric take-out device (3), a warp beam, a warp beam driver and a control device coupled to the warp beam, The control device receives a command for drawing in the yarn. After receiving the command for drawing in the yarn, the fabric take-out device 3 draws out the knitted fabric using the fabric take-out device 3 so that the warp connected to the knitted fabric is drawn in. controlling the fabric take-out device 3 for drawing in, and during the control of the fabric take-out device 3 for drawing in, the warp beam rotates and actively releases the replacement warp wound on the warp beam and control the warp beam driving unit.
