Moving yarn thermal treatment unit - with profiled insert in guide channel held in place by sprung clamp for easy assembly and dismantling

摘要

Thermal treatment unit for processing moving thread or yarn material has a heated metal block with guide troughs with a profiled insert. The cross section of the guide trough is semicircular. The profiled insert, when in position, matches the cross section of the guide channel and is held in place by two angled flanges. The insert is held in place by the flanges through a groove to accommodate one flange on one side, and a clamp to give a sprung pressure on the other flange. Appts. is partic. for heating units of length >1 m; the design ensures that there is close contact between the insert and the block to give good thermal conductivity, with easy assembly and dismantling.
