Knitting Action of the Compound Needle Warp Knitting Machine | KnittingAction of the Compound Needle Tricot Machine

Needle rise and guide bar swing: 

With the sinkers forward holding down the fabric, the hooks and tongues rise, with the hook rising faster, until the head of the latter is level with the guide holes and is open.The guides then swing through to the back of the machine.

2. The overlap and return swing:
The guides shog for the overlap and swing to the front of the machine; immediately, the hooks and the tongues start to descend with the tongues descending more slowly, thus closing the hooks.

3. Landing and knock-over:
The sinkers start to withdraw as the needles descend so that the old loop is landed onto the closed hook and then knocked-over as it descends below the sinker belly. At this point the underlap occurs before the needles begin their upward rise and the sinkers move forward to hold down the fabric.

The Karl Mayer tricot model HKS 2–3 E is designed to knit elastic fabrics and has a maximum speed of 3300 cpm with reduced noise levels and energy consumption.The vertical staggered arrangement of the guide bars enables the stroke to be reduced.The bars are hollow section which reduces their weight and expansion due to heat.
