Abstract
There is provided a tab tape splicing apparatus for automatically fastening a tab tape on the adhesive surface of a rolled pressure-sensitive adhesive sheet at the end of the roll to provide a rolled pressure-sensitive adhesive tape with a tab at the leading end thereof. The apparatus comprises a rail fixedly mounted between a pair of upright frame members on both sides of a base to extend in the breadthwise direction of a pressure-sensitive adhesive sheet, a movable frame movable from side to side along the rail, a splicing roll attached to the movable frame for fastening a tab tape, a tape holder for holding a roll of tab tape, cutting means for cutting the tab tape, and means for moving the movable frame from side to side.

An apparatus for splicing a tab tape to a pressure-sensitive adhesive sheet comprising:
- a guide rail arranged opposite to an adhesive surface of a pressure-sensitive adhesive sheet and extending in the breadthwise direction of said sheet;
- a movable frame slidably carried on said guide rail and having a tab tape holder;
- an arm pivotably attached to said movable frame and normally biased into an upright position by a spring to guide, press and fasten a tab tape to said adhesive surface of said pressure-sensitive adhesive sheet;
- a splicing roll rotatably attached to one end of said arm;
- a stopper attached to said movable frame to restrain the movement of said arm in said upright position;
- a ratchet mechanism mounted on said movable frame whereby said arm is allowed to rotate in a direction in which said arm is tiltable;
- a projecting rod provided at a starting position of said movable frame on said guide rail to release said ratchet mechanism;
- a hydraulic piston cylinder unit provided at a terminal position of said movable frame on said guide rail to rotate said arm in said tiltable direction;
- cutting means for cutting said tab tape between said splicing roll and an end edge of said pressure-sensitive adhesive sheet;
- and drive controlling means for reciprocating said movable frame between said starting position and said terminal position.
