Abstract
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.
Claims9
A method of separating stacks of individual shaped items from precut stacked strips of the shaped items, comprising the steps of superimposing individual shaped items in multilayer stacked strips of the shaped items with the shapes of the shaped items fitted into one another, applying downward pressure against said stacked strips substantially along a horizontally non-straight line which corresponds in configuration to a horizontally non-straight punch line between said individual shaped items corresponding to the shape of said individual items, and separating stacks of the individual shaped items along said punch line.
A device for separating stacks of individual shaped items from precut stacked strips of the shaped items, comprising:
- a punching table;
- punching means movable relative to said punching table for separating the stacks;
- presser means for holding the strips during the separation of the stacks;
- said presser means including a clamping member shaped for pressing against said strips along a horizontally non-straight line which corresponds in configuration to a horizontally non-straight line of cut between successive stacks of said items.
A device for separating stacks of individual shaped items from precut stacked strips of the shaped items, comprising:
- a punching table;
- punching means movable relative to said punching table for separating the stacks;
- presser means for holding the strips during the separation of the stacks;
- said pressure means comprising means for adjustably holding down said stack in the vicinity of an intended line of cut, said means for holding down including means for varying a contour along which said means for holding down presses against said strips wherein said means for adjustably holding down the stack comprise a replaceable clamping member shaped to extend to said line of cut between said successive stacks of said items and inserted into said presser means, said clamping member having an under surface downwardly inclined towards said line of cut.
