The rectangular counter-die band, (1) is provided that has corrugated edges (2) formed by alternating peaks (3) and valleys (4), designed such that, when mounted around the corresponding die cutting cylinder (8), the corrugated side edges (2) of the band determine lines of intersection with non-linear adjoining bands (1), thereby preventing the die cutting blades from cutting along said intersection lines. The band also includes corresponding end projections (5) comprising corresponding tongue-and-groove coupling recesses (6) and protrusions (7), both the band (1) and the projections (5) being made from polyurethane and being characterised in that the ends of the band (1) can be provided with projections (5′) having a corrugated outer profile formed by valleys (6′) and peaks (7′), thereby facilitating the intercoupling of the ends of the band (1).
A counter-die band for a cylinder of a rotary die cutting machine capable of being mounted around the cylinder where the cutting die acts to prevent the deterioration of the die-cutting blades, the band comprising a rectangular polyurethane element with complementarily-shaped end projections and recesses to facilitate the intercoupling of the band around the cylinder and the locking of said cylinder on the relevant key groove, the corrugated edges of the band having an undulated pattern consisting of alternating peaks and valleys so that the lines of intersection with adjoining bands around the cylinder that do not follow a linear circumferential pattern, thereby preventing the die cutting blades from cutting along said intersection lines while rotating.
