Weighting Arms PK 1550 SeriesSpring loaded drafting system for roving frames

Increased efficiency for the production of high quality rovings.

The weighting arms PK 1550 series offer more flexibility for the spinning process and an improved process reliability, thus resulting in rovings of optimum quality.

These are the convincing features of the PK 1550 series:- Flexibility without any compromise- Optimized surface protection- Smaller load tolerances- Visible load indicators- Ergonomic handle- Top apron cradle concept with individual

tensioning system- Easy disassembly of top rollers

The PK 1550 weighting arms are intended for 3-roller and 4-roller drafting systems on cotton type roving frames. They are suitable for spinning cotton, man-made fibres or blends thereof of up to approx. 60 mm length.

The PK 1550: improved process reliability

PK 1550 SERIES 5

The visible load indicators of PK 1550 Easy monitoring of individual load

setting at each weighting element

New features for safe and easy operation: The visible load indicatorThe visible load indicators of PK 1550 weighting arms allow you to see which load has been set at each weighting arm at a glance. The status of the blue triangle clearly indicates the load step setting of the respective weighting element. In this way the load set at the weighting arms can be easily monitored and corrected throughout the entire roving frame.

4-Roller Drafting System

The 4-roller weighting arm PK 1550-6008 947 (28 mm Ø top rollers), which is designed for 4-roller drafting system, differs from the 3-roller version in having an additional condensing zone between the roller pairs I/1 and II/2. By deliberate-ly condensing the fibre material in this zone, a reduction in the spinning delta is achieved, thus improving the incorporation of the fibres into the roving.

This results in the following important advantages:- Reduced number of roving breakages

(improved process reliability)- Increased efficiency- Greater package density at roving frame bobbin

thanks to the more compact roving4-roller version PK 1550-6017 295 (28 mm Ø top rollers), which is designed for 4-roller drafting sys-tem, differs from the 3-roller version in having an additional drafting zone between the roller pairs III/3 and IV/4.

Top Apron Cradles for PK 1550 SeriesConcept with individual tensioning system

Depending on the application and fibre length, the weighting arms of PK 1550 series can be fitted with different top apron cradles for cotton, man-made fibres and blends:

Short top apron cradle OH 5022up to 45 mm fibre length

OH 5022 OH 5042 OH 5245

Medium top apron cradle OH 5042up to 54 mm fibre length

Medium top apron cradle OH 5042up to 60 mm fibre length

OH 5022 and OH 5042 top apron cradles are characterized by individual apron tensioning, thus ensuring perfect fibre guidance throughout the entire roving frame.

The advantages of the individual tensioning system: - Low-friction and gentle apron running thanks

to the special surface structure and ideal com-bination of materials give the apron unit a low drive torque and ensure a long working life of the top aprons

- Individual tensioning of top aprons per spinning position

- Lowest possible stress on the fibres during drafting and gentle fibre guidance

- Time-saving apron exchange without the need to remove the top apron cradle unit

- Easy handling of the apron cradle unit
