A cutter box and clamp assembly is provided in a spreading machine for laying fabric or other sheet material on a cutting table, for the purpose of cutting off the sheet material at the end of each layer which is spread. The assembly includes a housing mounted on the spreading machine carriage, a cutter frame movably mounted in the housing, a cutter disc rotatably mounted on the cutter frame and drive apparatus for moving the cutter frame and the cutter disc, carried thereby, from one end of the housing to the other. A spring-mounted pressure bar bears against the edge of the cutter disc and the sheet material is fed between the cutter disc and the pressure bar. A clamp member operates to clamp the sheet material to the pressure bar prior to operation of the cutter disc. When the cutter frame is driven in a cutting stroke, the cutter disc rolls along the pressure bar and traverses the sheet material forcing its way through the material to perform a scoring cut and causing the material to part. After the sheet material is cut, the machine carriage moves to the opposite limit of its travel and the cutter box cooperates with a catcher assembly to place the cut end of the sheet material onto the cutting table.
