Abstract: A process and a device for folding a sheet longitudinally and transversely, in which the lower folds and the upper folds of a plurality of pairs of longitudinal folds of a Leporello fold are formed in sequence by fold straight edges that are movable towards each other, the front edges of the fold straight edges being moved along an arcuate path to the sheet in order that there is contact between them and the sheet only at the end of said movement. The longitudinally folded sheet is then laid on the parallel contact edges of the transverse fold plates that are arranged at intervals adjacent to each other, and pressed together therebetween, the areas between the transverse fold plates being pressed downwards by pressure elements which are moved upwards and out once again prior to the completion of the movement of the transverse fold plates towards each other. Thus it is possible to form all the transverse folds in one stage of the process.

Then the lip is formed into a curl edge section which ends in an inner curl diameter that is round and concentric with the chuckwall.

Abstract: This invention provides an apparatus and method of setting up apparatus for the automatic cutting and/or shaping of IC components carried in a tubular carrier and advanced for processing by gravity. A base plate is disposed at an angle of approximately forty degrees to the horizontal and provides a supporting means for gravitational feeding of these components from a removable U-shaped retainer to a guide and then to a die station. At this die station a resiliently tired feed wheel engages the body of the IC component which is metered and advanced with an intermittent motion. This motion is provided in a timed relationship with two rotating shafts which have pins moved in a precise orbit around a shaft centerline. These pins are one-hundred-eighty degrees out-of-phase with each other. The rotated feed wheel and attached tire are intermittently moved in a strict timed relationship to the movement of the two shafts by a one-way clutch driven by one of the shafts and by an eccentrically moved Pitman arm.

Abstract: A diminishing arm toggle linkage has the work site within the toggle geometry and thereby provides exponential force enhancement. In preferred embodiments the mode of operation shifts on demand from a light-load-pivoting mode to a heavy-load-rolling element mode thereby easing operation and reducing friction and wear so as to provide prolonged durability and continuing dimensional accuracy. When the toggle linkage is embodied in a crimping tool an optional anti-reversing ratchet assembly prevents the tool from opening during use until a crimp is completed.
