Drafting systems for roving frames
PK 1550 mechanical weighting arms
The spring loaded weighting arms PK 1550 offer more flexibility for the spinning process and an improved process reliability, thus resulting in rovings of optimum quality. The PK 1550 weighting arms are intended for 3-roller and 4-roller drafting systems. They are suitable for spinning cotton, man-made fibres or blends thereof of up to approx. 60 mm length.
Available gauges: 90 / 100 / 110 mm
Features
- Optimised surface protection for long life
- Smaller load tolerances
- Visible load indicators
- Ergonomic handle
- Top apron cradle concept with individual tensioning system
- Easy disassembly of top rollers

PK 5000 pneumatic weighting arms
The PK 5000 series weighting arms are an innovative and future-oriented drafting system for short staple roving frames. It can be used for spinning of cotton, man-made fibres and combinations of these up to a fibre length of approx. 60 mm. The load on the top rollers is adjusted infinitely and centrally using a compressed air supply system. This ensures a constant load at all spinning positions of the roving frame. The PK 5000 weighting arm offers an extremely practical method of centralised partial load, which is easy to set and persuasively simple to operate.
Available gauges: 90 / 100 / 110 mm
Features
- Simple and easy to operate
- Rapid erection and setting
- Simple height adjustment
- Centralised and infinite load setting
- Practical and safe partial load
- Reduction in the operating forces
Types
- PK 5025 3-roller version (Top roller diameter 28 mm)
- PK 5035 3-roller version (Top roller diameter 35 mm)
- PK 5025 4-roller version (Top roller diameter 28 mm)
- PK 5035 4-roller version (Top roller diameter 35 mm)
Technical information
A comprehensive safety concept based on three steps:
A pressure monitor ensures that the ring spinning machine is secured against dropping out of air pressure below the limit of 3 bar.
