Abstract
In a device for cutting single blister packs from a blister band, a cutting member acts in a longitudinal direction with respect to the blister band, along the longitudinal edges thereof, so as to cut side extending strips of the blister band which extend beyond the length of the blister pack being produced. Cut out elements operate in alignment with a cutting line of the cutting member to cut shaped pieces of the blister band, so as to define corner zones of the blister packs. Shearing means operate crosswise to the blister band, in alignment with the corner zones defined by the cut out means, to separate single blister packs. The position of the cutting means and cut out means and/or the shearing means can be adjusted to produce blister packs having different sizes.
Claims8
A device for cutting blister packs, having a selected crosswise dimension or length, from a blister band driven in a forward direction to a shearing station of a blister packing machine having shearing means for crosswise severing blister packs on the blister band, the device comprising:
- cutting means situated before said shearing means, said cutting means operated along side edges of said blister band for cutting side strips extending beyond said crosswise dimension or length of said blister packs;
- cut out means situated after the cutting means and before said shearing means for cutting shaped pieces of said blister band in alignment with a cutting line of said cutting means, to define corner zones of said blister packs;
- said cutting means being movable crosswise with said cut out means for adjustment of the crosswise dimension or length of said blister packs when the size of the blister packs is changed, the distance between said cut out and said shearing means being adjustable for adjustment of a lengthwise dimension or a width of said blister packs when the size of the blister packs is changed and for making the shearing means act in a region of said corner zones defined by said cut out means.
