Abstract
Equipment for cutting sheet material includes a plurality of pairs of blade units and counter-blade units slidable and fixable on respective support members, elongate in a direction perpendicular to that of the flow of the material being cut. 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.

Equipment for cutting sheet material for example plastics, comprising:
- a plurality of pair of blade units (10) and counter-blade units (12) slidable and fixable on respective support members (14), elongate in a direction perpendicular to that of the flow of the material being cut, the support members (14) being common to a plurality of blade units (10) or counter-blade units (12), the equipment including:
- a first carriage (16) for positioning and moving the counter-blade units (12), which can move parallel to the elongate support member (14) of the counter-blade units (12) and which has means for selectively engaging each of the counter-blade units (12) and means for locking each of the units (12) individually and selectively relative to the elongate support member (14),
- a second carriage (18) for positioning and moving the blade units (10), which can move parallel to the elongate support member (14) of the blade units (10) and which has means for selectively engaging each of the blade units (10) and means for locking each of the units (10) individually and selectively relative to the elongate support member (14),
- drive means which can drive the first (16) and second (18) carriages to move uniformly and in synchronism with each other,
- means for detecting the axial position along the respective support member (14) of at least one of the carriages (16, 18), and
- a control unit (74) for controlling the drive means, the selective engagement means and the selective locking means,
- said equipment being characterized in that the means for selectively engaging the counter-blade and the blade units (12, 10) of respectively the first and second carriages (16, 18) comprises a support structure (48) on which is mounted a respective actuator (54) including a piston, the distal end (58) of which is shaped so as, in its extended position, to be able to engage a pin (60) which projects from each blade unit (10) and counter-blade unit (12) respectively.
