Abstract: In an automatic system for spreading material, such as fabric, rolled on bolts, a spreading portion includes a driven carriage supported for reciprocal movement over a fixed table and between two spaced catcher assemblies mounted on the table. A tensionless loop is maintained in the material as it is fed from a bolt carried by the carriage and spread over the table. Maximization of the spreading operation without damaging the material is accomplished by making the rate of carriage travel responsive to the rate of material feed. The catcher assemblies prevent the material from following the carriage upon each direction reversal, after which cutting means therein severs each end loop. A storage and loading portion is preferably utilized with the spreading portion. The storage and loading portion includes a conveyor for advancing bolts of material into engagement with an elevator assembly, which reloads the carriage. A microprocessor is utilized to control operation of the entire system.

Abstract: An apparatus for cutting a plurality of selected lengths from a rod-like workpiece. A plurality of annular saws or mills have cutting teeth formed on the inner annuli which have diameters greater than the diameter of the workpiece. The workpiece is passed through the annuli such that the distance between one saw and the end of the workpiece defines one selected length while the distances between each pair of adjacent saws define the other selected lengths. The saws and the workpiece are relatively rotated in opposite directions, while concurrently the saws are moved transversely to bring the teeth of the saws into cutting engagement with the workpiece. If the apparatus comprises two annular saws, the annular saws are moved in opposite transverse directions so that the saws are concurrently engaging opposite sides of the workpiece. The transverse movements of the saws are controlled such that the saw nearest the end of the workpiece completes its cut first.

Abstract: A cutter for cutting continuous stock materials into discrete lengths is disclosed. The cutting device includes a plurality of rotatable cutting tools or blades extending transversely across a cutting zone. The cutting tools are mounted in a common plane, are intermeshed, and are synchronously driven in opposite directions. The cutting zones of the intermeshed cutting tools overlap and thus the cutting device is capable of performing the cutting operation by movement in one direction through the material being cut. The cutting tools have opposed segments that carry cutting edges. In one form of tool, the cutting edges are spaced from the axis of rotation of the cutting tool by a distance that continuously increases in a direction opposite the direction of rotation of the cutting tool. This change in distance can be related to the speed of rotation of the cutting tools and the speed at which the cutting tools are advanced through the material being cut.

Abstract: In that type of sheet metal shear having upper and lower rotary cutters to which power is supplied, both to cut a sheet of metal overhanging a work table edge and to propel the shear along the line of cut, unexpected capacity is achieved. The upper and lower cutters are powered each with separate motor. The cutters are driven through bevel gear sets; the upper motor is positioned with clearance above the work table, with its shaft slanting downward to the bevel gear intersection. Using the separate upper motor eliminates the transmission of power along and across the upward slanting bridge portion of the frame aft of the cutters. With this function eliminated, the bridge portion may be lower, requiring less power to deflect the scrap being cut off. With this saving of power added to the saving from using the efficient bevel gear sets, heavier gauge sheets are slit with less power than heretofore required for thinner sheets.
