Abstract (en)

[origin: US4790223A] For separating off a stack of individual shaped items such as bottle neck labels from a stack of strips each carrying several such items, a punching die is used which has a punching contour which corresponds to the desired shape of the cutting line between the individual shaped items. The cutting line also corresponds to the rear contour of the separate stack of individual shaped items. The shape of the cutting line of the punching die is freely selectable. At its rear edge the punching die is smooth and the separated-off stack of shaped items accommodates any compression of the material forming the stack by means of an offset angle so that the remainder of the strip of shaped items has a smooth and perpendicular cut edge.
