Abstract: A device for singling out products that are grouped in blister packs or similar multiple packages includes a support structure for at least one multiple package to be singled out, with a bearing surface defining a reference plane. A holding device can be activated selectively in order to hold the at least one multiple package against the bearing surface. A cutting head includes a cutting unit, preferably an ultrasound unit, with a device for cutting the multiple package, and a control is operatively connected to the cutting head and to the holding device in order to control relative movement between the cutting unit and the multiple package in accordance with a cutting scheme which is predetermined or is defined in real time, and which depends on the configuration of the multiple package.

Abstract: A workpiece holding-down structure is used in a blind cutting machine and adapted to hold down a blind in a cutter unit of the blind cutting machine. The workpiece holding-down structure includes a workpiece feeder abutted against the cutter unit, and a clamp installed in the workpiece feeder. The clamp has a clamping bar unit fastened pivotally with a bottom wall of the workpiece feeder near one lateral side of the workpiece feeder and adapted to push a blind been put in the workpiece feeder toward the other lateral side of the workpiece feeder and to further hold down the blind for cutting.

Abstract: A clamping miter box including a base having a surface, a plurality of holes positioned in a pattern in the surface of the base, and a cam peg including a shaft sized to be rotatably receivable by a selected one of the plurality of holes and a cam portion coupled to the shaft for rotation therewith. The cam portion for engaging the item to be clamped.

Abstract: Device for cutting sheets of material, with a counter (12) for the material to rest on, a blade to cut the material, and a holdfast (11) that can be lowered onto the material by a mechanism (10) and raised off it by a spring (6). When the spring in such a device breaks, the holdfast can drop and injure the operator. The object is to prevent such injuries. An interceptor (7, 8, & 9) accordingly brakes the holdfast when the spring that raises it is broken.

Abstract: A wall-mounted support system for a sheet-cutting machine employs a workpiece clamping unit, and a set of rack units to provide endwise support for the workpiece. The clamping unit is comprised of confronting, elongated members of U-shaped cross section, connected by pairs of identical pivot arm components which are, in turn, assembled with pins that provide bearing elements. The rack units incorporate leveling bars, the attitudes of each of which is adjusted by use of an eccentric fixture.

Abstract: A die body is provided defining a longitudinal channel therethrough including the cross-sectional shape of a metal stud to be cut and an opening is formed through the die body extending normal to the web of the channel and including a first arm portion extending along one longitudinal margin of the channel and a second arm portion extending from the first arm portion to a point spaced slightly inward of the other longitudinal margin of the channel, the first arm portion of the opening including opposite side portions thereof disposed inward and outward of the one longitudinal margin of the channel.

Abstract: A circular saw machine has a workpiece support and a clamping means consisting of a clamping arm and a clamping block for clamping workpieces; the clamping means is displaceable and clampable in a shaped groove with the aid of sliding members. The sliding members have first inclined faces and slide on corresponding second inclinded faces of the clamping block. Their slide movement may be initiated by means of a screw spindle connecting the two sliding members. When the sliding members slide upwards the clamping means is firmly clamped in the shaped groove. When they slide in the opposite direction clamping is released.

Abstract: A die body is provided defining a longitudinal channel therethrough including the cross-sectional shape of a metal stud to be cut and an opening is formed through the die body extending normal to the web of the channel and including a first arm portion extending along one longitudinal margin of the channel and a second arm portion extending from the first arm portion to a point spaced slightly inward of the other longitudinal margin of the channel, the first arm portion of the opening including opposite side portions thereof disposed inward and outward of the one longitudinal margin of the channel.

Abstract: A device for making miter cuts in workpieces includes a saw guide pivoted to either a bottom surface B or a top surface A of a board. The saw guide includes two plates spaced above the board surfaces by a pivot assembly and a swing assembly. Almost any commercially available circular power saw may be accommodated by placing the saw base on the plates, positioning the saw blade within alignment slots in the assemblies, and adjusting rails on the plates against the saw base. A keeper on one of the rails prevents the saw from jumping out of the saw guide. When the rails are properly adjusted, the circular saw blade will travel along a saw line between the plates from alignment slot to alignment slot. The top surface A of the board has a straight edged backup adjacent a planar work area. 90.degree. and 45.degree. stops on the top surface reliably and accurately position the saw line normal to or at a 45.degree. angle to the straight edge and aligned with 90.degree. and 45.degree. slots in the backup.

Abstract: A motor operated circular miter chop saw is pivotally mounted on a generally horizontal axle pivot bolt about which it rotates in a vertical plane with the axle pivot bolt being carried by a cast support base structure. Angular orientation of the work-piece is provided by an angularly adjustable fence rotatably carried by the cast base support structure. Clamping means are also provided selectively mountable with the cast support base to provide hold-in clamping action for holding a work-piece against the fence or mountable with the fence to provide hold-down clamping action for holding a work-piece against the cast support base.

Abstract: A power shear has a pair of parallel frame plates spaced apart to either side of a fixed blade and a movable blade. The movable blade can be displaced past the fixed blade to shear a workpiece extending across the plane and resting on the fixed blade A holddown plate is slidably mounted in rails on one of the frame plates and has a pair of edges guided by the rails and overreached by teeth formed on these rails. These edges of the holddown plate are formed with notches that can be aligned with the teeth to allow removal of the holddown plate in a direction perpendicular to its plane. A positioning spindle threaded through a nut fixed on the one frame plate can have an enlarged head engaged in a T-shaped cutout of the holddown plate so that when the holddown plate is lifted perpendicularly off the frame plate it is also disengaged from the positioning spindle.

Abstract: A hydraulic cylinder mounted on a frame assembly is communicated with a hand operated pump for actuation thereby. A plurality of punch-die assemblies, to be selectively mounted in the frame assembly for perforating, notching clipping or like operations, each comprise a punch or punches carried by a punch holder constrained to up-and-down motion relative to a die. When placed in the frame assembly, any selected punch-die assembly has its punch holder disposed under a ram connected to the piston of the hydraulic cylinder, so that upon manual activation of the pump, the punch or punches can be forced down to perform a desired operation in cooperation with the die. The punch and die assembly has a presser which urges the workpiece against a lateral side of the punch, and the workpiece can be acted upon at two locations at the same time, one location being directly above the other.

Abstract: An automatic BX cable cutter including a cable guide and clamp, a circular saw carried by a floating pivoted carriage actuated between cutting and inactive positions by a cam, the machine being so electrically coordinated that, when the saw motor is started and the cable end is inserted into its guide to a pre-set stop point, the clamp screw moves to cable-holding position, and the feed motor permits the carriage and saw to be raised to cutting position; after the cut has been made, the saw is retracted, the clamp screw drive is reversed and the cable is released.
