ABSTRACT:
An automatic machine for forming an adhesive tape tie around the gathered together neck of a filled bag includes a tie former including a reciprocating gripper (41) for pulling a length of pressure sensitive adhesive tape (33) across the path of the gathered together neck of a filled bag and for holding the tape (33) across the path with its adhesive side towards the bag and a clamp (34, 35) for clamping the adhesive side of the adhesive tape (33) around the gathered together neck and onto itself to form the tie. The machine applies folded V-shaped tabs (48) to the adhesive side of the tape (33) on its passage from a supply wheel (43) to the gripper (41), and a cutter (40) cuts the tape (33) to form each tie immediately above each V-shaped tab. The clamp (34, 35) brings the other end of the tie into adhering contact with the other limb of the V-shaped tab (48) to provide a pilfer proof tie with a single tab (48) secured across both ends of the adhesive tape (33) forming each tie.
