<p>Drawing roller for winding machines etc In the roller interior is an induction coil and a core which magnetises the roller jacket. The core consists of easily magnetised sheet metal which is radially evenly distributed over the whole roller circumference and fixed on a stationary tube coaxially placed inside the roller. Specif. the tube consists of a material with a low thermal and electrical conductivity stainless steel). The metal sheet is welded onto the tube and secured by a radial ring. an adhesive resin filler separates the metal sheet's ends facing the roller. Used in stretch/twisting, stretch/winding or spinning/stretch winding machines.</p> |
