A batcher-type sheet material winding apparatus includes a pair of driven winding rollers in spaced axially parallel relation for supporting a winding core peripherally between the rollers. A pivotable subframe supports the rollers for selective positioning in a horizontally adjacent winding disposition and a vertically adjacent core discharge position. One winding roller is driven at a constant peripheral speed equal to the traveling speed of the material, the other roller being driven at either a slightly greater speed to achieve dense material compaction or at a gradually decreasing speed to achieve uniform material winding density. A stationary cutting blade and a relatively rotating cutting blade transversely shear the material upon discharge from the winding rollers. An air discharge nozzle arrangement wraps and tucks the leading edge of material following a cut about a replacement core for resumption of winding opeation. A microprocessor automatically controls all apparatus operations.
Apparatus for winding a traveling sheet of continuous-length material onto a supporting core, said apparatus comprising a pair of winding rollers rotatably mounted in spaced axially parallel relation, means for moving one said winding roller relative to the other said winding roller between an operative winding position wherein said one winding roller is disposed relatively horizontally adjacent the other said winding roller for cooperatively supporting the core peripherally between said winding rollers and a discharge position wherein said one winding roller is disposed at a sufficiently increased vertical spacing relative to the other said winding roller in comparison to the operative winding position to cause ejection of the core gravitationally from said winding rollers, means for rotatably driving at least one of said winding rollers for driving rotation of the core to progressively wind the traveling sheet of material about the core, means for receiving and supporting the core at a spacing from said winding rollers upon ejection of the core, and means operable following ejection of the core for shear cutting the sheet of material transversely across its length at a location intermediate said winding rollers and said receiving and supporting means.
