Abstract
The invention provides apparatus for reducing the working area for cutting on a cutting machine for cutting a stack (1) of sheet material, the machine being provided with an automatic moving cutting tool (4) and with suction apparatus for holding the stack covered in air-impervious film (5) down on a cutting table (3) having a conveyorized support surface 3a. The apparatus comprises the air-impervious film (5) for covering the stack (1), an air-impervious movable mask loop (6) designed to cover a portion of the table (3), and a low friction block (65) for positioning the mask (6) over the portion of the table. The mask (6) covers the portion of the table and holds down the film (5) and the mask (6) when suction is applied beneath the table. The mask (6) is able to move across the portion of the table when a conveyor (62) transfers the stack (1) by use of the conveyorized support surface 3a.
