Patent ID: 8171835

Claim:
An apparatus for chamfering fold formation tape ends, the apparatus comprising: a restricting member for restricting the position of one end of a workpiece tape on a platform; a vertically-movable arresting force applying member for applying an arresting force onto the workpiece tape from above while one end of the workpiece tape being received by the restricting member; a pair of form cutters for simultaneously cutting into the workpiece tape obliquely from above so as to form acute-angled ends and chamfering the workpiece tape, said pair of form cutters placed opposite to each other in an axial direction of the workpiece tape with the arresting force applying member positioned intermediate therebetween, and arranged such that the cutters are inclined downward toward their cutting edges so that the cutters can move downwardly on the platform, driving means for advancing and retracting the pair of cutters in relation to the workpiece tape in conjunction with a vertical movement of the arresting force applying member; and an operating section for operating the driving means; wherein the cutting edge of each of the form cutters has a specified rake angle on the upper face that extends from the center to both sides respectively to form a specified rake angle, and by entering the workpiece tape with their cutting edges directed and inclined downward, processed ends of the workpiece tape are cut to have the same acute angle as the cutting edges in plan and chamfered at the same time.
