Abstract: Apparatus and method for twisting thin strip material such as thin aluminum strip in which the strip material is guided from a supply of strip material along a feed path 21 to a guide mechanism 11 which maintains the strip in a first plane and is then passed to two rolls 31, 32, at least one of which is driven. The rolls have on their outer circumferential edges 33, 34 grooves 41 which grip opposite edges of the strip, the rolls 31, 32 being mounted so that their axes of rotation are twisted with respect to one another whereby the strip is driven forwards by the rolls 31, 32 and twisted as it passes through the rolls to form a helically twisted strip.

Abstract: This relates to a double seam tightness monitor wherein the second operation track of a cam of a double seaming apparatus or can closing machine is modified so as to permit the high dwell portion of the lobe thereof to deflect under loading from the associated cam follower which forces the second operation roll against the double seam component. Suitable strain gauges are associated with the deformable cam track portion and these are coupled in a bridge having a voltage output which is directed to a microprocessor. The microprocessor is provided with selected inputs which in combination with the voltage input from the bridge may be utilized to provide various signals including a high force condition signal, a pass condition signal, and a low force condition signal. There may also be associated with the microprocessor a printer for identifying the station where an abnormal condition exists, the specific force of the abnormal condition, the machine number, the time and the date.

Abstract: A headpiece assembly for forming a rolled flange on the border of a collar associated with an annular lid. A sleevelike headpiece is axially slidably supported on a shaft and projects downwardly so as to surround and cooperate with a plurality of clamping levers. The clamping levers at the lower free ends have a clamping part which moves into a radially inward position wherein the clamping part is axially aligned below an annular flange-forming recess, the latter being formed on a pressure plate which is mounted on the lower end of the shaft for limited axial movement therebetween. The pressure plate and the lower free ends of the levers are disposed axially downwardly from the sleevelike headpiece. Downward movement of the headpiece cams the clamping levers radially inwardly to a position below the pressure plate, and causes the headpiece to engage the pressure plate and move it downwardly so as to effect formation of a rounded flange on the metal collar.

Abstract: A method of controlling a tension levelling equipment for correcting residual distortions in an extension of strip including a series of input and output bridle roll means for rendering a tension upon the extension of strip extending between the input and output sides of a levelling mill station for smoothing out the distortions, and slipping clutch means connecting the bridle roll means with driving means allowing a slipping motion therebetween, which comprises the steps of measuring a current tension rendered upon the extension of strip at both the input and output sides of either of the input and output bridle roll means, and controlling the engaging torques of the slipping clutches in such a manner that a current slipping motion produced between the extension of strip and the bridle roll means may be nullified or eliminated according to the result of measurement of tensions, whereby it can remove all possible defects such as flaws and scratches in the surface of a strip product caused from the slipping mo

Abstract: A tubular metal member undergoes expansion transverse to the longitudinal axis of the member. An axial compressive load is applied to the member parallel to the member's longitudinal axis, and the member is allowed to deform transversely to said axis. Procedures are employed to control the deformation of the member, to prevent the member from buckling, and to ensure that the ends of the member will be expanded uniformly with the remainder of the member.

Abstract: A slide is vertically movable in a press frame and supports the upper die. A threaded main spindle is operative between the press frame and the slide. A clutch disc connected rationally rigidly to the spindle is connectable by friction contact to a driven disc flywheel for the operating stroke of the slide. Piston-cylinder units act between the press frame and the slide for returning the slide to the starting position. The spindle is axially clamped between two spring columns, one of which acts between one end of the spindle and the slide and the other of which acts between the other end of the spindle and a counter thrust bearing axially fixed in the press frame.
