Abstract: A flying saw apparatus for severing a predetermined length of material from a continuously moving length of material is disclosed. A saw carriage is supported on a main frame assembly for reciprocating motion parallel to the direction of motion of the material. The saw carriage includes a saw bridge which extends transversely of the direction of motion of the saw carriage and is movable upwardly and downwardly. A saw shuttle, which carries a circular saw, is supported for reciprocating motion on the saw bridge. The saw carriage is connected through a drive mechanism to the main power drive of the material conveyor preceding the flying saw apparatus. The reciprocating motion of the saw carriage is transferred to reciprocating transverse motion of the saw shuttle by a rack and pinion mechanism.

Abstract: Process and apparatus for cutting an elongate complex structure composed of materials having different properties, e.g. a liner and a core which are relatively soft and flexible and susceptible to rupture or crushing and a facing of hard material such as a metal plate. The facing may have an upwardly turned portion, flange portion and groove portion at each side thereof. A carriage and a base frame are movable in the direction of the travel of the complex structure and in the direction perpendicular thereto, respectively. Various types of cutters are mounted on the carriage. The complex structure is instantaneously cut in the direction of the width thereof while it is travelling at a high speed. The cut composite structure has smooth and fine cut edges, and is useful for e.g. a siding of a building.

Abstract: A ram driven tube cutting apparatus of the double cut type in which sections of tubing are successively severed from a continuous length thereof by a notching cut followed by a severing cut, includes improved mechanism for clamping the tubing during the cutting process. A pair of opposed, complemental die jaws are mounted on slides controlled by spaced cam followers carried by the slides. A reciprocating wedge cam engages and forces the cam followers apart to move the slides thereby closing the jaws on the tubing. One of the cam followers comprises a roller mounted on an eccentric shaft which may be selectively rotated to adjust the clearance between the die jaws. The other cam follower is spring loaded toward the cam within a slide mounting provided in its slide and automatically shifts to an overload position to avoid damage to the mechanism when foreign objects become lodged between the die jaws.

The apparatus comprises a crank mechanism driven by a single, multi-function drive source and is adapted to perform the functions of four devices simultaneously, in a timed relation, namely a device for reciprocating a cutter in the direction of travel of the product or section, a device for advancing and retracting the cutter relative to the section, a device for driving a die opposed to the cutter, and a device for driving a clamp which holds the section during the cutting operation.

Abstract: Continuously cast plastic strip has interspaced marks or defects with lengths of unmarked usable strip therebetween. To obtain a maximum possible yield of sheets from such strip, the lengths of the portions between the marks or defects are measured and cut into sheets of two or more different lengths, the cutting being such as to produce the maximum yield of sheets of either or all lengths, singly or in combination, which can be obtained from the length cut. This procedure reduces the loss or waste due to the marks or defects, to a minimum. A special system is provided for this practice and for cutting out the marks or defects between the unmarked strip portions free from defects, with a minimum of loss or waste. Other features are involved.
