  • Patent number: 6205898
    Abstract: An apparatus for cutting a movable sheet of web material onto predetermined lengths including a pair of upper and lower cutoff rolls and a retractable cutoff blade. A slide mechanism is utilized to move in a direction transverse to the movement of the sheet of web material to selectively engage and disengage the cutoff blade.

  • Patent number: 4939967
    Abstract: A cut-off machine for cutting off predetermined lengths from a moving length of roll form material such as tubing adapted to be positioned downstream from a source such as a tube mill for receiving a moving length from the mill and severing plural predetermined lengths from the moving length. The machine comprises a plurality of cut-off assemblies which are reciprocated longitudinally of the moving length of material formed by the mill and operated during the movement to sever plural predetermined lengths. The reciprocating and cutting movements are mechanically derived from a motor driven in synchronism with the speed of movement of the moving length. The apparatus includes mechanisms that permit the length of the tubes to be changed while the machine is operating.

  • Patent number: 4856395
    Abstract: This invention relates to a cutting mechanism and its method of operation in "cutting side-lock" portions from "green state" roofing tiles. The tiles are manufactured in a conventional concrete roofing tile making plant in which mortar fed to a hopper extruder (18) of conventional design is formed as a continuous ribbon (26) on a series of pallets (P) conveyed beneath the hopper extruder (18). The ribbon (26) is thereafter cut by a knife (3) into discrete tiles (T) on said pallets (P) with a "side-lock" portion of each tile being blanked out by extension portions (32) (34) of the knife (30). The blanked out portions are thereafter removed from the remainder of the tiles by a blade 90 of removal means 14 such that no damage is caused to the tiles (T) and little or not detritus remains on the tile or the conveyors of the tile making plant.

  • Patent number: 4082023
    Abstract: A device for measuring and cutting cables in chosen lengths at its rerolling for delivery which device comprises rotatable cutting tools, a measuring wheel and a grip-and-pulling-wheel, where the grip-and-pulling-wheel when pulling the cable is connected to a clutch mechanism arranged to be electromagnetically set either to let the grip-and-pulling-wheel pull the cable and to prevent backward motion of the cable or to allow motion of the cable both forwards and backwards.

  • Patent number: 4073260
    Abstract: Cross welds in metal tube moving continuously along a path are removed by means of a method which includes the sequential steps of generating signals representative of predetermined linear movements of the tube, detecting the presence of cross welds in the tube and, on detecting the presence of such cross welds, passing signals to a counter device which is operable after receiving a predetermined number of these signals to actuate a cutting device which removes the cross weld from the tube.
