Abstract
The invention relates to the preparation of a stack of knitted fabric panels for subsequent cutting. It consists in spreading the knitted panels under extension over the needles of a needle table, covering the formed stack over with a sheet of material impervious to air, creating a reduced pressure inside the stack by sucking in the air contained between the table and the sheet, retracting the needles from the stack and proceeding to the cutting while keeping up the suction throughout the cutting operation. The needle table comprises a table top perforated with holes, a movable support on which are fixed the needles and a tight box containing the movable support and equipped with suction means.
