Weighting arms Texparts® PK 5000 Series

The standard drafting system for short staple roving frames

The Weighting Arms Texparts® PK 5000 Series are an innovative and future-oriented drafting system for cotton roving frames, for the spinning of cotton, chemical fibres and combinations of these up to a fibre length of approx. 60 mm.

With a completely pneumatic weighting system, they embody the latest technology for today`s drafting systems. With the Texparts® PK 5000 the weighting pressure on the top rollers are adjusted infinitely and centrally using a compressed air treatment system. This ensures a constant loading at all spinning positions of the roving frame.

A comprehensive safety concept based on three steps:
1. Detecting:  pneumatic unit
2. Finding:    the individual flow indicator on the arm permits dependable checking of each arm and rapid location of possible leakage in it
3. Rectifying: short time required (approx. 1 minute)

A pressure monitor ensures  that the ring spinning machine is secured against dropping out of air pressure below the limit of 3 bar.
