ABSTRACT:
A device for cutting slits in plastic tubes produces a plurality of cuts spaced around tubing passed through the device. The device comprises a plurality of rotatable members (3) located at different circumferential positions around a tube passage (2) through the device. Each rotatable member is provided with a tube cutter (25) which is directed at and away from the tube passage (2) with rotation of each member (3). These rotatable members (3) are adjustable radially of the tube passage (2) for accommodating diametric variances in the tubing.
