texparts


PK 1500 Series Weighting Arms Proven draft system for convincing roving quality Series PK 1500 weighting arms are intended for 3-roller and 4-roller double apron draft systems on short fibre roving frames. They are suitable for spinning cotton, man-made fibres or blends thereof up to approx. 60 mm length. The PK 1500 weighting arms are easy to operate and ensure rovings of high quality. The PK 1500 weighting arm series comprises the following types: 3-roller double apron draft systems  PK 1500-0962 604 (28 mm Ø top rollers)  PK 1500-0962 602 (35 mm Ø top rollers) 4-roller double apron draft systems  PK 1500-0001 938 (28 mm Ø top rollers)

The 4-roller weighting arm PK 1500-0001 938 (28 mm Ø top rollers), which is designed for 4-roller double apron draft equipment differs from the 3-roller version in having an additional condensing zone between the roller pairs I/1 and II/2. By deliberately condensing the fibre material in this zone, a reduction of 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 breaks (improved process reliability)  Increased efficiency  Greater package density at roving frame bobbin thanks to the more compact roving

Top Rollers Proven components with precise running behaviour High quality top rollers with high loading capacity Top rollers used in the PK 1500 weighting arms are products of the latest state-of-the-art roller bearing technology and have become standard components of today‘s top quality draft equipment. They are characterized by the following features:  Small roller diameters  Long service life at high load capacity  Sturdy, high-quality ball bearings  Precise running behaviour  Completely hardened axles  Ground saddle for precise seating in the weighting arm  Minimized friction  Reliable bearing seal  Long service intervals  Simple maintenance The top rollers are supplied as standard without cot. If required, however, Texparts can also supply mounted and ground top rollers.

LP 1015 for PK 1500 Top roller for use as rear and front top roller. Roller diameter 19 mm. Diameter over cot 28 mm or 35 mm (only 3-roller-version).

LP 1017 for PK 1500 Top roller for use as apron top roller as standard. Roller diameter 19 mm. Diameter over cot 25 mm.
