Claims
- 1. A method of operating a surface winder having a source of cores and a nip for receiving cores to be wound comprising sequentially moving cores from said source to said nip along a path characterized by a plurality of cusps, a first cusp being located adjacent said source, a second cusp being located adjacent adhesive applying means and a third cusp being located adjacent said nip, a core transport member being provided for supporting said cores along said path, said member being orbited while a supported core is revolved therearound to provide said cusps, and selectively communicating vacuum to said member to engage a core at said source and to disengage a core at said nip.
- 2. A surface winder comprising a frame, means on said frame for delivering a web to a winding station for winding on a core, and core transport means on said frame for delivering a core to said winding station, said core transport means including means on said frame for moving said core through a generally hypocycloidal path, said transport means being equipped with vacuum puck means for gripping a core along the length thereof, and vacuum program means operably associated with said transport means for selectively applying and turning off vacuum so that a core may be picked up and discharged selectively.
- 3. A surface winder comprising a frame, means on said frame for delivering a web to a winding station for winding on a core, and core transport means on said frame for delivering a core to said winding station, said core transport means including means on said frame for moving said core through a generally hypocycloidal path, said core transport means including stationary shaft means fixed in the said frame, arm means rotatably mounted on the said shaft means and rotatably carrying core transport roll means in spaced parallel relation to said stationary shaft means, first pulley means operably associated with said frame for rotating said arm means and thereby orbiting said core transport roll means relative to said stationary shaft means, second pulley means operably associated with said stationary shaft means for rotating said core transport roll means, puck means on said core transport roll means extending generally radially thereof for engaging a core and vacuum means interconnected between said frame arm means core transport roll means and puck means for selectively engaging and releasing cores sequentially.
