Abstract:
1. An automatic rewinding machine for receiving a web material for winding on cores to form logs, said web material being in continuous motion and having spaced apart lines of perforations, the machine comprising a first winding roller around which said web material is moved; a second winding roller; and a third winding roller; said first winding roller, said second winding roller and said third winding roller positioned for simultaneously contacting a log during at least a portion of the winding of the web material on a core; a core inserter; and a movable web material separator wherein said web material separator is constructed and arranged to selectively move at a peripheral speed faster than a speed of the web material or move at a peripheral speed slower than the speed of the web material, and is adapted to periodically pinch said web material between said web material separator and said first winding roller when the peripheral speed of said web material separator and the speed at which the web material is moving are different, to thereby cause said web material to separate along a line of said lines of perforations at a point in said web material located between a newly inserted core and a nearly completed log.
