Improved rewind system

A winder for winding a continuous web material or interleaved web segments into rolls, said winder comprising:

• a plurality of winding spindles orbiting about a winding turret axis, said winding turret axis being generally parallel to said cross-machine direction, each of said plurality of winding spindles being arranged to be rotatably driven about an axis generally parallel to said winding turret axis, each of said winding spindles being driven at a surface speed;
• a plurality of surface contact rolls, each of said plurality of surface contact rolls being cooperatively associated with a respective winding spindle of said plurality of winding spindles, each surface contact roll of said plurality of surface contact rolls having a longitudinal axis generally parallel to said winding turret axis, each of said plurality of winding spindles and said surface contact roll cooperatively associated thereto being capable of cooperative engagement when said web material is disposed therebetween, each of said winding spindles being capable of receiving said web material when said winding spindle is proximate said web material and cooperatively engaged with said respective surface contact roll;
• a controller cooperatively associated with each of said plurality of surface contact rolls, said controller being capable of adjusting a surface speed of each of said plurality of surface contact rolls;
• and,
• a web separator adapted to periodically pinch said web material disposed between said web separator prior to said web material contacting a respective winding spindle of said plurality of winding spindles and said surface contact roll cooperatively associated thereto and the surface speed of the each surface contact roll is different from the surface speed of said winding spindle cooperatively associated thereto for an entire wind cycle.

A winder for winding a continuous web material or interleaved web segments into rolls, said winder comprising:

• a plurality of winding spindles disposed upon a winding turret indexable about a winding turret axis through an endless series of indexed positions, said winding turret axis being generally parallel to said cross-machine direction, each of said plurality of winding spindles being arranged to be rotatably driven about an axis generally parallel to said winding turret axis, each of said winding spindles being driven at a surface speed;
• a plurality of surface contact rolls, each of said plurality of surface contact rolls being cooperatively associated with a respective winding spindle of said plurality of winding spindles, each surface contact roll of said plurality of surface contact rolls having a longitudinal axis generally parallel to said winding turret axis, each of said plurality of winding spindles and said surface contact roll cooperatively associated thereto being capable of cooperative engagement when said web material is disposed therebetween, each of said winding spindles being capable of receiving said web material when said winding spindle is proximate said web material and cooperatively engaged with said respective surface contact roll;
• a controller cooperatively associated with each of said plurality of surface contact rolls, said controller being capable of adjusting a surface speed of each of said plurality of surface contact rolls;
• and,
• wherein said longitudinal axis of each surface contact roll of said plurality of surface contact rolls is adjustable relative to said axis generally parallel to said winding turret axis when said web material is received by said winding spindle cooperatively associated thereto and the surface speed of the each surface contact roll is different from the surface speed of said winding spindle cooperatively associated thereto for an entire wind cycle.
