Abstract (en)
There is described an apparatus (1) for splicing a new web (3), provided with repeated patterns, to a web in use (2), also provided with repeated patterns and fed, at a working speed (W) and along a predetermined path (P), to a processing machine; the apparatus (1) comprises: a first and a second support hub (11, 10) respectively supporting in use a first and a second reel (5, 4) of the webs (2, 3) to be spliced and rotating about axes (E, D) parallel to one another; joining means (13) arranged adjacent to a working portion (P1) of the path (P) and selectively activated for adhesively bonding a segment (3a) of the new web (3) to a segment (2a) of the web in use (2) in an overlapped position; and cutting means (14) to perform a cutting operation on the web in use (2) at an area thereof located upstream of the overlapped and bonded segments (2a, 3a); the first and second support hub (11, 10) are independently rotated about their axes (E, D) by first and second actuator means (27, 26), respectively; the joining means (13) comprise pressing means (75) selectively activated to press the segments (2a, 3a) onto one another while passing along the working portion (P1) itself and while the segment (3a) of the new web (3) is advanced by the first actuator means (27) at the working speed (W) of the web in use (2).
