ABSTRACT:
An unwinding machine for adhesive tapes comprising a frame on which two tape reels are mounted and successively unwound by independent driving means outside the machine. Each of the reels is associated with a driven launching roller and the launching roller is displaced away from the tape being unwound from the operative roller whereas the launching roller associated with the spare reel which is at rest, is operated to engage the end of the tape therefrom to unwind the tape and bring the spare reel up to speed when the tape on the operative reel is approaching the end thereof. First and second rollers are provided for each reel adjacent the path of the tape from the respective reel to the location outside the machine, the rollers defining two opposed straight travel sections for the tape. Cutters and pressing members are associated with each of the rollers so that the first cutter associated with the operative reel being unwound and the second cutter associated with the spare reel are simultaneously operated when the speeds of the two reels are the same for cutting the tape of the operative reel being unwound and the tape of the spare reel leading to the launching roller while at the same time, joining the cut ends of the tape along a portion of the travel section by the pressing members.
