Abstract
A tape splicing apparatus in which two tapes are quickly joined with no air bubbles entrapped by splicing tape. A drum body holds splicing tape by suction pressure applied through holes and the peripheral surface of the drum. The splicing tape is cut into segments of predetermined length upon the drum surface. The drum is then lowered to the splicing position upon stationary and movable receiving stands to press the sticky side of the tape segment against the abutting tape joint. A movable roller presses the splicing tape segment, which was initially attached along only a single line, in forward then rearward directions from the center of the joint so that no air can be entrapped under the splicing tape.
Claims19
A tape splicing apparatus comprising:
- a drum body for feeding splicing tape toward the ends of first and second tapes to be butt-joined with said splicing tape and having means for retaining a non-adhesive surface of said splicing tape on the circumferential wall of said drum body;
- driving means for turning said drum body intermittently in one direction;
- a tape cutting knife for cutting said splicing tape on the circumferential wall of said drum body in the widthwise direction of said splicing tape into segments of splicing tape having a predetermined length;
- means for depressing a part of the adhesive surface of a segment of splicing tape against the butt-joint of said first and second tape with said drum body;
- and
- depressing roller means for bonding the entire adhesive surface of said segment of splicing tape to said first and second tapes while preventing the formation of air bubbles between said tapes thus bonded.
