ABSTRACT:
A cutter for use with looms has a positionally stable, rotating first cutting member (1) and a rotating second cutting member (2) which is moveable in relation to the first cutting member. The cutting members are connected in a frictional manner by an energy storing device (8) and rotate in opposite directions. The movable second cutting member (2) is mounted so that it can freely rotate on an axle (6), which is retained in a torsionally secure manner in membrane springs (11), which are elastically deformable in the axial direction in order to compensate for the lateral deflections of the rotating, positionally stable first cutting member (1), as a result of which the service life of the cutters is extended. The device is particularly suitable for a series shed loom because a high cutting rhythm can be achieved.
