Abstract
There is disclosed herein a device for achieving and maintaining the optimum positioning of the cutting die and platen components on a die cutting machine used for cutting and scoring paper, plastic, leather, cloth, metal, and other like materials. The device compensates for inherent deviations present in each individual die cutting machine. The invention is comprised of a rigid lightweight metal substructure bonded to an overlayment of a semi-rigid material possessing a unique combination of elastic and compressible properties which allow the cutting knives in a steel rule die to lie in the same horizontal plane as the movable platen.
Claims10
In a die cutting machine comprising a cutting section and a supporting section;
- the cutting section including a cutting edge arrangement;
- the supporting section including a platen holder and a platen mounted on the platen holder, the platen facing the cutting die and adapted to support an item to be cut;
- the cutting section and supporting section being relatively movable to cause the cutting edge arrangement and platen to come into contact with one another during a cutting operation;
- the improvement comprising:
- a leveling device comprising an aluminum base plate, an elastomeric sheet formed of an elastomeric polymer, and a bonding agent disposed between the base plate and the sheet for bonding the base plate to the sheet, a total thickness of the leveling device being in the range of 0.048 to 0.158 inches;
- the leveling device positioned between the die holder and the cutting die whereby portions of the elastomeric sheet are elastically compressed in response to contact between the cutting edge arrangement and the platen for enabling the cutting edge arrangement to assume a parallel relationship with the platen.
