Guide bar segments for knitting machines - have plastic moulded guide formations on each segments

摘要

The product is a yarn guide for knitting machinery which is in the form of segments to place together as a guide bar. Each guide of the segment is set apart to match the distance between the needles with which they function. At each end of the segment as half a guide distance. Pref. the segment has a base with fixing hole. The protrusions are shaped to form the yarn guides. Another protrusion keeps the yarn in the guide slot. The shaped part has a pin form leaving the place for the yarn. The yarn is brought from a beam in direction to each guide. The segments are arranged to fit together on a bar, and the end of one segment fits against the adjacent segment. Where needle spacing is close, the guide at segment ends will have to be formed in two halves. This is achieved with a plastic injection moulding technique, which can be formed as mouldings as an open channel, or projections as studs or pins, tubular passages, holes and slots, or combination of these. The segments may also have end formation to clip together. The segments may have a double formation to enclose the yarns when two parts are closed together, giving a quick release for threading purposes. The double sections are also arranged to have a snap action to clip together. Other separate elements may also be employed to secure the yarns into the guides. ADVANTAGE - The segments are easily handled, they quickly form into a bar, with reliable performance. The product is precise, efficient and long lasting. Setting up time is reduced.
