Abstract

An improved device (10) for the winding of rolls with and without core, especially suitable for the winding of a film (50) for plastic bags, applied to a rotation turret or head (33) of an apparatus or machine for winding (7) and comprising pairs of opposite grippers (11, 13) longitudinally developed, co-axially and symmetrically arranged with respect to a vertical plane and longitudinally developed, coaxially and symmetrically arranged with respect to a vertical plane and each with one of the two ends (20) apt to allow the hooking to a structure for moving said grippers in an axial sliding with respect to a guide bushing (22) and to at least one support flange (34) attached with respect to the apparatus or machine for winding (7) and coaxial one to the other, with the guide bushing (22) arranged between said support structure (20) and said support flange (34), the pairs of grippers comprising each one an upper gripper (12, 16) and a lower gripper (14, 18) opposite one to the other, with said pairs of grippers provided with a fixed tongue (24) suitable for coupling with the exterior of a core (46) and for hooking the film (50) for driving the same, said device likewise comprising mobile means with magnetic drive apt to couple with at least one further core (46) fitted on the same pair of grippers for the hooking and the driving of a further film (50) to be wound into a roll.
