Sheet winding apparatus

Apparatus for winding a traveling sheet of continuous-length material onto a supporting core, said apparatus comprising:

• (a) a pair of winding rollers rotatably mounted in spaced axially parallel generally horizontally adjacent relation for cooperatively supporting the core peripherally between said winding rollers;
• (b) means for rotatably driving at least one of said winding rollers for driving rotation of the core to wind progressively the traveling sheet of material about the core;
• (c) a discharge arm assembly mounted above said winding rollers for movement between an inactive position spaced thereabove during winding of the sheet of material onto the core and a discharge position contacting the core to eject it laterally from said winding rollers;
• (d) means for receiving and supporting the core at a spacing from said winding rollers upon ejection of the core;
• (e) 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;
• said discharge arm assembly and said shear cutting means being affixed together for coordinated movement of said shear cutting means in following relation to said discharge arm assembly;
• said receiving and supporting means includes a pair of supporting rollers rotatably mounted in spaced axially parallel relation for cooperatively supporting the core peripherally between the supporting rollers, means for rotatably driving at least one said supporting roller for driving rotation of the core, and means for applying a peripheral wrapping about the core during rotation of said supporting roller for preventing undesired unwinding of the sheet of material from the core.

• (f) means operable following shear-cutting of the sheet of material for directing a stream of air against a leading end of the sheet of material following the location of shear-cutting to wrap the leading end about a replacement core supported on the winding rollers and means for engaging the leading end when wrapped about the replacement core to insert the leading end into a nip between the replacement core and one said winding roller, said means for engaging the leading end of the sheet of material being mounted to said shear cutting means;
• and
• said discharge arm assembly and said shear cutting means being affixed together for coordinated movement of said shear cutting means in following relation to said discharge arm assembly.
