TH28733A - Assembly for fitting the shaft cover of a terrate-type winding machine? - Google Patents

Abstract

The finished machine for sheet winding and the method of operation of such machine will be disclosed. The finished machine consists of a turret assembly, a core loading machine, and a core unloading machine. The turret assembly supports the drive shafts to rotate in coordination with the hollow cores as the paper sheets are wound onto them. Each shaft is driven in a closed, non-circular shaft trajectory. The core loading machine conveys the cores onto the shafts as the shafts move along the core loading segments of the closed shaft trajectory, and the core unloading machine removes each individually wound core from each shaft as the shafts move along the core unloading segments of the closed shaft trajectory. The turret assembly is continuously rotating and the number of sheets per lock can be changed while the turret assembly is rotating. The finished machine can also be equipped with shafts with deformable core loading assemblies.
