ABSTRACT:
A cutting machine for subdividing material lengths comprises a roller table establishing a transport path along which the material is directed to a cutting zone. A cutting head assembly has a cutting blade for cutting material located at the cutting zone. A front vise assembly is fixed adjacent to the cutting zone with first and second jaws arranged in opposed mutually spaced relationship on opposite sides of the transport path. A first jaw operating mechanism is provided for adjusting the spacing of the first and second jaws between an open position permitting movement therebetween of the material and a closed position clamping the material therebetween. A rear vise assembly is mounted on a carriage underlying the roller table. The carriage is movable in opposite directions parallel to the transport path. The rear vise assembly has third and fourth jaws also arranged in opposed mutually spaced relationship on opposite sides of the transport path. A second jaw operating mechanism is carried on the carriage and operates to adjust the spacing of the third and fourth jaws between an open position permitting movement of the carriage relative to the material and a closed position clamping the material therebetween, thereby establishing a fixed relationship between the material and the carriage. A carriage operating mechanism moves the carriage in opposite direction along the transport path.
