Abstract
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).
