ABSTRACT:
A cutter for tear-severing a web (N) driven around a rotating roller (10) wherein recesses (25) carried by the roller (10) cooperate cyclically with projections (23) external to the roller (10). The web material (N) is stretched beyond its breaking point between the recesses and projections (25, 23) when the projections (23) penetrate the recesses (25) without mutual contact. The tension in the web material (N) is caused by friction between the web material and the rotating roller (10).
