A machine for cutting foam material having an endless cutting wire (80) supported on a number of rollers (51, 52, 53, 54 and 55) to travel a fixed length continuous path. Two of the rollers (52, 53) being mounted to move along respective parallel paths in synchronism to displace that portion (81) of the wire (80) extending between the rollers (52, 53) in the plane of rotation of those rollers. A motor (42) to drive the endless wire (80) about the continuous path so the foam material presented to the portion (81) of the wire may be cut thereby. The displacement of the roller (52, 53) being controlled by a motor (69) under the control of an ECU (40) to determine the shape to which the foam material is cut.
