Winding device and method

An apparatus for winding a strip comprising:

• a rotatable motor driven mandrel, the mandrel having an outer surface for supporting the strip, the mandrel rotatable about a central axis,
• a pressure assembly comprising:
• a first pressure unit that is coupled to and rotates together with the mandrel about the central axis 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 the first pressure unit rotate about the central axis 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.
