Abstract: A strip-shaped supporting adhesive tape is joined to a ring frame, and then is stuck with a cutter blade such that the cutter blade penetrates the adhesive tape. In a state where a cutting edge of the cutter blade is brought into contact with a tape joined side of the ring frame, thereafter, the adhesive tape is cut along a contour of the ring frame while electric current is fed to each of the cutter blade and the ring frame. Herein, a sensor monitors a conduction status in real time.
Abstract: Cutter suitable for artificial flower stems. Typically, plastic coated wire stems are cut with hand cutters to various lengths in preparing artificial floral arrangements. The invention requires far less physical effort by the operator than is required when using conventional wire cutters. In the preferred use of the preferred embodiment of the invention, an uncut stem is inserted crosswise through two elongated holes in the guard housing. When the cutter jaws open, the stem is pushed into the open jaws and is cut to a desired length from the flower end when the jaws close. In the preferred embodiment of the invention a gear reduction motor drives an arm and cam roller assembly. That cam roller forces the top handle of the cutter downward causing the jaws to close. As the cycle continues, the cam roller raises and a spring causes the jaws to open.
Abstract: During the forward driving of a recording motor, a platen roller is forwardly rotated and a de-curl shaft is rotated so as to bear against a recording sheet and at this time, a cutter is not driven. During the reverse driving of the recording motor 31, the cutter 17 is first driven to cut the recording sheet 14, whereafter the platen roller 15 is reversely driven and the de-curl shaft 27a becomes spaced apart from the recording sheet 14.
Abstract: A sawmill includes a band saw mounted on a trolley. The trolley carries the band saw back and forth across the length of a log to cut it into boards. A log supporting table is adjustable to accomodate logs of various size. The trolley rails descend incrementally after each cut to reposition the band saw blade for the next cut. The length of each increment, or board thickness, is user selectable by way of an indexable detent bar and limit switch combination. The thickness across the board is held uniform by a pressurized bellows that maintains the proper blade strain in the band saw blade.
Abstract: A portable radial arm machine having two principle components. The machine is easily disassembled and quickly assembled in either a working mode or in a compact portable mode having the characteristics of a piece of luggage so that the machine can be transported easily from location to location and readily placed in operation.
Abstract: In order to drive a punching machine electrically, with the aid of a double-armed rocker (70) a translational motion for the compression beam (10) is generated on the one hand, and a rotary motion for an opposing drive on the other hand. On the one side, the double-armed rocker (70) is driven by a rotating clutch shaft (50) by way of a crank gear (60-66) and, on the other side, a chain link (73) serves to control the compression beam. The opposing drive is operated by means of a one-arm rocker (75) and, also, by means of a chain link (76). To ensure the execution of an exact cycle, an engaging and disengaging claw clutch (31, 36) is present. The cycle is maintained by a cam disk arrangement (51) on the one hand, and a coupling groove (37) on a coupling box (32) with a coupling bolt (38), on the other hand. The above provides the electric drive for a rectilinear punching machine for punching sheets of paper for mechanical binding systems.
Abstract: A guillotine assembly is provided wherein a blade is insertable between two halves of an anvil to cut a paper web. The blade is provided with teeth which engage triangular grooves in a resilient member of the anvil which is pressed against a rigid anvil plate. Points on the teeth first penetrate the web. Thereafter, tooth mid-sections form a series of slits in the web. Thereafter, points of contiguity between the teeth jam the slits to sever the web. The teeth each enter one of the grooves in the resilient member for the points of contiguity to engage and displace the resilient member in the final stage of cutting.
Abstract: Method for operating an automatic hollow punch search device and relevant control, for die-cutting machines, particularly for footwear production, in which a mobile head is associated to a device to move it to and fro, both horizontally and vertically, above a fixed faceplate on which the material to be cut is placed, together with a hollow cutting punch. The movement devices are automatically piloted by a drive circuit interlocked to manual starting device which provides means to carry out a complete head movement operating sequence from its positioning above the hollow punch to its lowering and return to the starting point after cutting.
