Beschreibung
Zusammenfassung:	The invention concerns an assembly for cutting strands formed by thermoplastic filaments, and comprising a blade-holder wheel (1) and an anvil-wheel (2) rotating in reverse direction about two parallel axes (x1, x2), at least means for actuating (B) said wheels and means (6) for contacting a strand with the anvil wheel (2). The invention is characterised in that it further comprises: means oscillating (3) the support of said wheels (1, 2) whereof the axis (x3) is parallel to the axis of said wheels and associated actuating means (A); means (C) for contacting said wheels; means (10) designed in particular to pinch said strand and associated actuating means for passing the strand between the blade-holder wheel (1) and the anvil-wheel (2) when said wheels are not in contact. The invention further concerns the associated method.
