Waste stripping unit with simplified tool change for a packaging production machine
First Claim
1. A waste stripping unit for a packaging production machine, the waste stripping unit positioned downstream along a path of substrates after a cutting unit for cutting the substrates, the waste stripping unit comprising:
- a frame;
two rotary tools supported by the frame for cooperating with one another, at least one of the two tools including a mandrel and a removable sleeve, the removable sleeve being removably inserted on the mandrel and fixed on the mandrel, and the removable sleeve is driven in rotation by rotation of the mandrel;
a front bearing for at least one of the two tools, the front bearing being movable between a first position that allows extracting the sleeve from the mandrel and a second position that retains the sleeve on the mandrel; and
a rotation shaft for the at least one of the two tools;
an arm comprising one end supporting the front bearing at the one end of the arm, the arm sliding transversely to the path of the substrates and pivoting between a locking position locking the rotation shaft of the tool and a releasing position releasing the rotation shaft of the tool enabling extraction of the sleeve from the mandrel, and vice-versa.

Abstract
A waste stripping unit in a packaging production machine (1), positioned downstream of a cutting unit (3) for cutting one or more flat substrates (4). The stripping unit includes a frame (16) supporting two rotary tools cooperating with one another (17, 18). At least one of the two tools (17, 18) is formed with a mandrel (27) and a removable sleeve (28), and the sleeve can be inserted on, fixed to and driven in rotation by the mandrel (27). One tool has protruding needles for the stripping and the other tool has a flexible strip cooperating with the needles.
