A parent roll of paper unwinds from a back-stand to feed a wide web of paper to a perforator, web separator, core-feeder and log rewinder. The perforator includes a stationary ledger blade and a rotating knife-blade roll which cut lines of perforations across the web. The web separator includes a pair of operatively opposed rolls rotating in synchronism, one of which has a spiral groove while the other forces the web of paper into the groove to tear the web within the grooves. A secondary winder rol is disposed in spaced relation to the first winder roll. The secondary winder roll can be slowed down to cause the core to advance between the first and second winder roll. A control is disposed near the secondary winder roll to limit the outer dia. of the finished log of paper.
