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.

A method for forming yarn pressing weave by using a groove pin warp knitting machine based on servo driving. The method is performed on a Raschel groove pin warp knitting machine, and specifically comprises: a. enabling a groove pin body (3) to rise for a first time, utilizing a sinker (5) to press against an old coil, utilizing a yarn pressing guide comb (1) to perform traverse movement before the pin, and finishing yarn laying; b. enabling the groove pin body (3) and a groove pin core (4) to descend, enabling the groove pin body (3) to be kept open, and enabling pressed yarn (6) and the old coil not to undergo ring sleeving and to together move into a pin hook; c. enabling the groove pin body (3) to rise for a second time, utilizing the sinker (5) to press against the old coil and the pressed yarn (6), and enabling the old coil and the pressed yarn (6) to together slide to a pin rod of the groove pin body (3); enabling a ground yarn guide comb (2) to perform traverse movement before the pin and finishing yarn laying; d. enabling the groove pin body (3) to descend for the second time and to be closed, enabling the old coil and the pressed yarn (6) to undergo ring retreating together, enabling ground yarn (7) to form a new coil, enabling the pressed yarn (6) to be wound around the bottom of the new coil, and forming the yarn pressing weave. The groove pin body and the pin core are controlled by a servo motor to move up and down to form the yarn pressing weave, and a yarn pressing plate in the prior art is omitted.
