Sealing system for a cutting table having vacuum clamping

A sealing system for a moving vacuum grip cutting table for laminar material, said cutting table comprising:

• a conveyor loop mounted for movement in a stationary table, said stationary table comprising a frame, a feed end having a feed zone, and a collection end having a collection comb and a collection area for supporting received laminar material, said conveyor loop having an upper substantially horizontal leg for transporting the material to be cut;
• said upper horizontal conveyor leg having a first end located at the feed end of said stationary table and a second end located at the collection end of said stationary table;
• means for driving said conveyor loop such that said upper horizontal conveyor leg moves from said feed end to said collection end;
• a first conveyor loop curvature next to the first end of said upper horizontal conveyor leg;
• a second conveyor loop curvature next to the second end of said upper horizontal conveyor leg;
• said conveyor loop being formed by a plurality of successive, adjacent tiles, each tile having a mat surface permeable to air;
• means for producing a vacuum in the mate of the adjacent tiles defining the upper horizontal conveyor leg;
• movable means for vacuum sealing at least the mat of the tile in the upper horizontal conveyor leg at said second end immediately adjacent said second conveyor loop curvature when said conveyor loop is stationary during material cutting, said movable means for vacuum sealing being disposed below said collection area.
