WINDING DEVICE AND METHOD

摘要

A winding device suitable for winding at least one strip on a mandrel. According to one embodiment the winding device includes a pressure assembly configured to press a strip against the surface of the mandrel when winding the strip. The pressure assembly comprises a first pressure unit which is coupled to and rotates together with the mandrel from a first winding position to a second winding position while the first pressure unit presses on the strip. The pressure assembly further comprises a second pressure unit that is attached to the first pressure unit, and that is configured for pressing on the strip when the first pressure unit reaches the second winding position, allowing forward movement of the strip in the winding direction when the mandrel rotates.

主权项

1. An apparatus for winding a strip comprising:
a rotatable motor driven mandrel, the mandrel having an outer surface for supporting the strip, a pressure assembly comprising:
a first pressure unit that is coupled to and rotates together with the mandrel in a winding direction between a first winding position and a second winding position, the first pressure unit being configured to press down on a first portion of the strip as the mandrel and first pressure unit move from the first winding position to the second winding position,a second pressure unit that is attached to and rotates with the first pressure unit, the second pressure unit configured to press down on a second portion of the strip down against the outer surface of the mandrel after the first pressure unit reaches the second winding position, allowing forward movement of the strip in the winding direction when the mandrel rotates,the first pressure unit configured to stop pressing down on the first portion of the strip when the second pressure unit acts to press down on the second portion of the strip.
