Abstract
The invention provides apparatus for reducing the working area for cutting on a cutting machine The apparatus comprises the cutting machine made up of a cutting table, the working area on the surface of the cutting table, an automatic cutting tool for cutting a stack of sheet material within the working area and a suction apparatus providing suction to the working area. An air-impervious film covers the stack and which holds the stack down within the working area when suction is applied. An air-impervious removable mask (6) covers a portion of the working area and is held in a determined position by fixing and positioning structures, such as a strip and an abutment attached to the mask. When the mask is held in the determined position, the working area is effectively reduced to a portion of the working area that is not covered by the mask.
