Abstract:
A die plate for use in at least one of impressing, cutting, scoring, and embossing a web of workpiece material, said die plate providing for magnetic retention in a selected locatable position upon a cylindrical magnetic die holder having thereupon circumferential and radial reference marks extending relative to a longitudinal axis of said die holder, said die plate comprising:(a) a thin flexible magnetically compatible material having a first surface defined by leading, trailing and two opposing side edges wherein at least one of the edges has a first alignment mark and a second alignment mark displaced by a predefined angle other than 90.degree. relative to the first alignment mark such that said first and second reference marks are not parallel;(b) a second impression surface raised above said first surface adapted to contact said workpiece material to perform at least one of impressing, cutting, scoring, and embossing said workpiece material, said impression surface having at least one of a leading impression surface and a side impression surface;(c) wherein said die plate is aligned at a predetermined first angular orientation corresponding to alignment of the first alignment mark to a selected one of said reference marks on said magnetic die holder; andwherein said die plate is aligned at a predetermined second angular orientation corresponding to alignment of the second alignment mark to the same selected one of said reference marks on said magnetic die holder;wherein at said first orientation at least one of said edges are aligned in a first position with the first alignment mark aligned relative to one of said circumferential and radial reference marks; andwherein at said second orientation at least one of said edges are aligned in a second position with the first alignment mark aligned relative to one of said circumferential and radial reference marks.
