The support members are common to a plurality of blade units or counter-blade units. The equipment further includes a unit for selectively engaging the blade and counterblade units with respective first and second carriages. The selective engagement units include a support structure on which is mounted a respective actuator including a piston, the distal end of which is shaped so as, in its extended position, to be able to engage a pin which projects from each blade unit and counter-blade unit respectively.</p> |
