Features The crochert warp knitting m/c:


1.A single horizontal needle bar whose simple reciprocating
  action can be used to operate  individually – tricked latch,
  carbine or embroidery needles.The patent or carbine 
  bearded needleis used for fine structures and has a side
  ways crimped beard placed in a permanently-pressed 
    position. Although warp threads can only be fed into the 
     beard from the left, the old overlaps are 
   automatically cleared and landed by the movement of the
   needle. The needles can be arranged for 
   coarser gauges or for fancy set-outs, when the floating 
inlay threads may be cut to produce separated fringed 
edgings.

  the knock over verge to preventthe fabric moving out with the
needles

  and supplied as separate warp and weft respectively

pile, braiding and snail shell designs.
