Abstract: A split-setting pull-type blind-riveting assembly comprising a hollow rivet and a mandrel. The underside of the mandrel head is frusto-conical and terminates at flat surfaces normal to the mandrel stem. A portion of the mandrel stem adjoining said plane is squared off so that its corners deform the rivet shank before the underside of the mandrel head splits it into petals. Reliable splitting of the rivet shank into uniform petals is thereby reliably achieved.

Abstract: In packaging machines using heat-sealable wrapping material it is important that the heat-sealing mechanism operates in synchronism with the rest of the machine under satisfactory sealing conditions. A control device for sealing bars (14, 15; 40, 41) disposed opposite one another is provided which reciprocates the bars (14, 15; 40, 41) towards and away from one another in phase with the packaging machine operation. The bars (14, 15; 40, 41), or a lever mechanism or mechanical linkage, have arms (16, 17; 54, 54a, 59, 59a) pivotted by integral pins (18, 19; 55, 55a, 56, 56a) with eccentric axes: second pins (19; 56, 56a) are pivotted on the frame and first pins (18; 55, 55a) are rotatable about the axis (80; 70) of the second pins (19; 56, 56a) on movement of arms (16, 17; 55, 54a, 59, 59a) in the closing, sealing phase.

Abstract: Apparatus for splicing the trailing end of an old web to a new web comprises a pair of tangential fixed rollers between which the old web is fed. At each side of the fixed rollers two further rollers are supported by arms pivotted on a pin lying in the tangent plane. The old web runs over one of these rollers, while on the other the starting end of the new web is supported with a double-sided adhesive tape thereon. The roller above which the old web runs is pivotted above the other roller so that the web runs between the rollers and the webs are spliced by raising the lower roller, as the old web runs out. A cutting device separates the tail of the old web. The upper roller is then moved back to its original position for preparing a new web.

Abstract: A heavy duty power operated blind rivet setting tool having a mandrel collection system for drawing the pulled mandrel through the tool to a collection canister at the rear of the tool. The tool is operated by a primary air supply and the mandrel collection system is operated by a secondary air supply located within the physical confines of the tool. A control valve is located in the secondary air line which can render the mandrel collection system inoperative.

Abstract: A stencilling apparatus having a single drive means operating a container fixture screen support and wiper fixture, so that the container fixture rotates and moves toward and away from the screen, and the screen moves laterally and the wiper moves toward and away from the screen all in timed sequence to wipe a screen pattern on the container.

Abstract: A device for automatically presenting fasteners in a predetermined disposition comprising a container for the fasteners which presents the fasteners to a rotary drum which raises the fasteners upwardly for deposit into a chute. The fasteners are fed down the chute to a ramp which positions individual fasteners in a predesired position in a feed barrel for receipt by a fastener tool. An escapement mechanism is positioned between the chute and the ramp so that a single fastener at one time falls down the ramp into the feed barrel.

Abstract: A blind-riveting machine comprises a transfer device having suction means to hold a mandrel stem and carry it into vertical alignment with a bore in a nosepiece of a rivet-setting device. With the blind-riveting assembly thus poised, the suction is released and the mandrel stem drops into the nosepiece, which holds the assembly when the transfer device retracts.

Abstract: A mechanism for stripping the tape carrying an electrical component to expose the component for removal from the tape. The cover strip is removed from the tape to expose the component and the tape is passed between guides that retain the component in the tape until removed therefrom.

Abstract: A cut-clinch mechanism for cutting and forming the leads of electronic components inserted into the openings in a printed circuit board, the mechanism having a fixed cut-clinch head supporting a movable cut-clinch head with a bi-directional drive means for incrementally moving the heads toward and away from one another to accommodate variable spaced component leads.

Abstract: A blind-riveting machine having a device for presenting blind-riveting assemblies to the nosepiece of a rivet setting head.
