Method for forming fall-plate weave by using groove pin warp knitting machine based on servo driving

Abstract

A method for knitting fall-plate structures on warp-knitting machines, including: the fall-plate guide bar makes an overlap when the groove needle bar is going upward and the previous loop is held by the sinker bar; the groove needle bar and the tongue bar simultaneously go downward but these two items are kept not closed, and the overlapped yarn and the previous loop are slipping inside together; the groove needle bar go upward again while both the fall-plate yarn and the previous loop are held by the sinker bar, making the two yarns slip out of the groove needle. Meanwhile, a ground guide bar makes an overlap, finishing lapping. When moving the groove needle bar downward for a second time, retreating the old loop and the pressed yarn; forming a new loop, by the ground yarn; placing the pressed yarn under the new loop; and forming the fall-plate structures.
