Abstract

Improvements in devices for joining the ends of two bands of a coil product used to feed printing machines or the like, where the devices are combined to uncoilers known per se, consisting of a frame, a pair of arms that pivot around of a shaft integral with the frame, a first coil of web material and/or film in the process of unwinding, arranged between one of the end portions of the pair of arms, a second coil, of web material and/or waiting film arranged between the other end portions of the pair of arms, a launching device applied at a given moment to the standby coil to imply a rotation speed synchronized with the rotation speed of the coil in the course of unwinding to obtain identical unwinding speeds of the two bands, a locking brake to stop, after the cut, the practically empty coil, character curled because they comprise, mounted on a frame, a band guide assembly, coming from the unwinder to guide it towards the utilization machine, a mobile assembly for the partial winding of the beginning of the band coming from the waiting coil and a retractable gluing and cutting assembly provided with means for maintaining a self-adhesive element and the end portions of the two overlapping bands.
