Converting machine with automatic rewinding coil change

Abstract

The present invention relates to a converting machine, i.e., a machine for winding or unwinding a strip of material on coils, particularly configured to process a delicate material. In particular, the invention is directed to a machine (1) for converting coils of a material into smaller coils, comprising a loading unit (2) for loading a strip (N) of material into the machine (1), an accumulation unit (3) of the strip (N) being processed, and a winding unit (4) of the strip (N) on a winding shaft (5, 5′) to form respective coils (B), characterized in that the winding unit (4) comprises: a revolving disc (29), which supports two winding shafts (5, 5′) of coils (B); a feeding roller (30) of the strip (N) to a winding position; a movable accompanying member (31) of the strip (N) and a cutting member (32) operatively associated with said feeding roller (30), wherein the feeding roller (30), the movable accompanying member (31), and the cutting member (32) are placed on a carriage (33), movable horizontally between at least one forward or operating position and a retracted or resting position; and wherein the movable accompanying member (31) and the cutting member (32) are hinged on the axis of the feeding roller (30) and are tiltable between a non-operating position and an operating position adapted to operate the crosswise cut of the strip M.
