Abstract: The disclosure discloses a control method of pattern loading for a high speed double needle bar warp knitting machine. Through disposing two or more than two high speed FIFO pattern data cache regions on a shog controller, a data read-write conversion function of each cache region continuously and automatically is respectively realized. Needle collision caused by guide bar shogging during pattern loading is avoided. Pattern loading steps of the double needle bar warp knitting machine are simplified; the work intensity is reduced; and the work reliability is improved.

Abstract: The disclosure discloses a control method of pattern loading for a high speed double needle bar warp knitting machine, and belongs to the technical field of warp knitting equipment. Through disposing two or more than two high speed FIFO pattern data cache regions on a shog controller, a data read-write conversion function of each cache region continuously and automatically is respectively realized. According to a current position of each guide bar, a target position of current shogging of an original pattern and a starting course position of a novel pattern, a control system of the double needle bar warp knitting machine automatically calculates a shogging displacement required by each guide bar in a pattern loading process, and sends out instruction information to a shog driving execution unit corresponding to each guide bar.

Abstract: A knitting method and an apparatus for a cylindrical biaxial weft-knitted three-dimensional knitted structure. The biaxial three-dimensional knitted structure comprises two weft plain stitch structures (7, 7?), a group of spacer yarns (416), two groups of weft inserting yarns (415, 415?) and a group of warp inserting yarns (43), wherein the two groups of weft inserting yarns are used for selective weft inserting on a needle dial (11) or a needle cylinder (13), the warp inserting yarns are positioned between the two groups of weft inserting yarns, the two weft plain stitch structures are connected with each other by the group of spacer yarns, for jointly clamping the weft inserting yarns and the warp inserting yarns, in order to form a biaxial weft-knitted three-dimensional knitted structure.

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.

Abstract: 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.
