Installation for cutting sheet material

An installation for automatically cutting sheets of material, said installation comprising:

• a plurality of stacking devices for stacking said sheets to be cut, said stacking devices including
• an outlet end, and
• a first electrical connection assembly, said first electrical connection assembly including
• an indexing element,
• a first connector portion, and
• mounting means having a set of two moving supports for enabling said indexing element and said first connector portion to move in two orthogonal directions, said first connector portion and said indexing element being mounted on said mounting means;
• and
• at least one cutting device, said cutting device including
• a second electrical connection assembly for cooperating with the first electrical connection assembly when the cutting device is in register with a corresponding stacking device, said second electrical connection assembly including
• a first connector portion, and
• a cam assembly, said cam assembly cooperating with said indexing element of said first electrical connection assembly for adjusting the position of said second electrical connection assembly along a displacement direction of the cutting device relative to the first electrical connection assembly of the corresponding stacking device,
• said cutting device further including
• a bench having a feed end, said feed end including means for mating with the outlet end of the stacking devices, a bench outlet end for unloading said sheets that have been cut out, and a top surface extending from said feed end to said bench outlet end, that defines a cutting zone,
• a support means which is displaceable with respect to said bench, said support means having a surface that faces the feed end of said bench,
• a cutting head mounted on said surface of said support means facing said feed end,
• a cutting conveyor and unloading conveyor, both conveyors being mounted beneath said top surface of said bench,
• turbine means for creating suction, said turbine means being disposed beneath said unloading conveyor, and
• means for supporting at least one roll of impermeable film, said supporting means being mounted about said top surface of said bench, substantially at the feed end of said bench, before said cutting head.
