Abstract
A plurality of curved plates which are adapted to be mounted on an embossing roll are identically engraved with an embossing pattern that matches the plate dimensions, permitting them to be interchanged or replaced without disrupting pattern discontinuity. In one embodiment, the pattern is created to match a given plate by laying out a skew grid matching plate corners, and using grid parallelograms as pattern unit cells. In another embodiment, an existing doubly periodic pattern is minimally distorted to match the plate geometry.
Claims12
A set of two or more circumferentially divided covering plates for covering an embossing roll and a lesser set of one or more spare plates, each of the covering plates and the spare plates having a plurality of edges and being provided with an outer embossing pattern which is cut by at least one of the edges of the plate, the embossing pattern being arranged such that part or all of the lesser set of spare plates can be used to replace any of said covering plates without creating pattern discontinuity where said spare plates abut said covering plates.
