Programmable apparatus for cutting woven fabric wound on a supply roll includes a fabric spreader which pays-off fabric from the supply roll and onto a cutting table as the spreader moves relative to the table. A vibrating member carried by the fabric spreader and over which the payed-off fabric is constrained to pass imparts vibration to a portion of the fabric which extends across the entire width of the fabric to relieve residual stresses within the fabric as it is spread onto the table surface. The spread fabric is immediately cut by a rotary cutting wheel which moves in cutting engagement with the fabric in response to command signals received from a programmable controller.
