RE-REELING MACHINE WORKING AT CONSTANT SPEED AND RELATED CUTTING DEVICE

摘要

The invention relates to a rewinding machine comprising a cylinder (11) adapted to transport a sheet material (40) is partially wound around thereof, a cylinder (13) movable winding being positionable by rotating a cam (18) adapted to support the coil (30 'and 30' 'respectively) in the winding phase and discharge, and a cylinder (23) for transferring exerting an elastic pressure on the coil, adapted to cause the coil in contact with the cylinder (13) winding. In said rewinding machine the tube (30) replacement meets the sheet material before reaching the axis of conjunction located between the cylinder (23) and the transfer cylinder (11) of transport. The cylinders always rotate at constant speed, the cylinder (11) for transporting and the cylinder (13) rotating winding at the same peripheral speed, while the cylinder (23) for transferring rotating at a substantially slower peripheral speed.
