tongue bar for warp knitting machine

TONGUE BAR

The tongue bar is an important processing part of the Warp Knitting Machine, the existing textile high-speed warp knitting machine Tongue bar structure type generally has two kinds: a Tongue bar for the pultruded carbon fiber substrate and an aluminum-magnesium alloy needle seat combination. Warp knitting machine tongue bar, comprising a Needle Bar substrate and a block fixed in the grooves of the bed substrate using epoxy resin bonding, is characterized by the fact that the bed substrate consists of 350 to 1100 layers of carbon fiber plain weave fabric bonded to each other using laminated layers and layers of epoxy resin. The melt grooves are rectangular and straight and are spaced at 20 to 30-mm intervals on the inserts. The thickness of the bottom of the melt groove and the bottom of the reverse core groove is 0.1 to 0.8 mm, and the cavities of each melt groove are filled with an epoxy resin layer. The needle bar is light in weight, the thermal expansion is almost zero, the bonding between the insert and the needle core bed base is solid, easy to process and maintain, has low production costs, low scrap rate, suitable for application in warp knitting machines.
