A core end engagement assembly is provided for a rewinding machine. The core end engagement assembly is configured to engage an end of the core and transmit rotational movement to the core during winding of the web material about the core. The assembly may include a drive housing. A chuck may project from a first end of the drive housing and may be configured to engage the end of the core. A first actuator may reciprocate the drive housing along a central axis of the core between an engagement and disengagement position of the chuck relative to the core. A second actuator may be mounted on the drive housing. The second actuator may be configured and adapted to move the chuck between release and hold positions. A flexible drive shaft operatively connects with and rotationally drives the chuck.

A winding machine for winding a finishing roll having a radius R of a sheet material on a core having a radius r.sub.c is provided. The winding machine includes: a support drum assembly arranged on a first side of the finishing roll and configured to support the finishing roll from the first side; a rider roll arranged on a second side of the finishing roll opposite to the first side and configured to apply a first nip pressure onto the finishing roll from the second side the finishing roll being supported by the support drum assembly; and a control unit configured to adaptively control the second nip pressure applied by the rider roll onto the finishing roll depending on an ascent rate of the rider roll.
