Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an apparatus for forming a plastic film acid handle for a carrier bag.

[Background Art] If the handle of a carrier bag has a stacked area, it is easy to grasp the handle and is convenient for both storage and transportation. However, it was difficult to remove the punching residue generated when forming a large stack.

[Object of the Invention] An object of the present invention is to provide an apparatus that allows punching residue to be easily removed and that allows for efficient formation of a large handle.

[Structure of the Invention] Therefore, the present invention provides a handle film between a receiving plate which is inserted along the lower surface side of the film for the handle and a groove portion formed along the direction in which the punching dregs are pulled out, and the receiving plate. A film presser that appropriately presses and clamps the vicinity of the hole forming position of the film, and a force lid for forming a finger size that advances toward the member with the handle film in between while being pressed and clamped by the film presser and punches out the stacked size. The punching scraps formed at the same time at the pile-up forming position are caught on the tip while the tip is moved within the groove, and the punching scraps are moved to the other end of the holder and removed from the handle film. The purpose is to achieve the above object by providing a removal mechanism.
