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: Continuous in-line control of work product is provided in draw-redraw processing of flat-rolled sheet metal, coil coated on both its surfaces with organic coating, to finished one-piece can bodies. Drawing of a sheet metal blank is controlled to present flange metal at the open end of the cup-shaped work product which is disposed with its closed end wall in the sheet metal line. The drawn work product is pneumatically controlled to separate the sheet metal line from the can line eliminating random accumulation of work product. Redrawing operations are carried out closed end up to present flange metal which stabilizes in-line movement of work product. Electrostatic lubrication to protect organic coating and facilitate forming is carried out prior to each redrawing operation; in-line movement of work product is controlled during such lubrication.

Abstract: A continuous process for high speed fabrication of wire comprises the steps of directing wire through a first set of drawing dies to reduce the wire diameter to an intermediate diameter, applying a lubricant to the wire during the drawing process, annealing the intermediate diameter wire while it is still coated with some of the lubricant, controlling the tensile forces and elongation of the wire during the anneal, and drawing the annealed intermediate diameter wire to a desired final diameter in a second set of dies. The process is partially well suited for fabricating fine copper wire having improved mechanical properties.

Abstract: Method and apparatus for forming end closures for containers complete with a peripheral curl for attachment to the top of a container without press modification includes a unique split die core ring. The method includes performing the operations of blanking the end panel against the cut edge, forming the chuckwall against the die core ring with a punch and punch shell and finally setting the chuckwall by wiping over the radius of the die core ring against a fluidly supported piston and simultaneously applying a curl to the peripheral edge of the panel prior to completion and removal from the press station. The method is performed by utilization of a split die core ring having inner and outer concentric segments, the outer segment of which is withdrawn as the punch shell advances to initiate a curl between the inner face of the punch shell and the outer face of the fixed inner segment of the die core ring.

Abstract: A hydraulic press with a pressure cell comprises a tray-shaped press plate with a bag-like diaphragm and a forming rubber pad and a press tray for a forming tool and a workpiece. The end wall portions projecting from the mid portions of each of the press plate and from the base of the press tray, provide thickness transitions which define a cavity in the operating position of the press tray. Between the press plate and/or the base of the press tray and the confronting force-absorbing surfaces of the yokes of the press frame of the press, play is provided in a portion above and below, respectively, the thickness transitions. This play allows the high stress levels which would otherwise arise at the thickness transitions to be reduced.

Abstract: A double acting press has a die carried by an upper slide thereby to be forced downwardly to engage a sheet metal blank between itself and a hollow blank holder, and a punch accommodated in the blank holder and thrusted upwardly by a lower slide for pressing the blank against the die. The blank to be formed must be placed horizontally on the fixed blank holder and the punch being held flush therewith in its lowermost position. In order to adjustably vary this lowermost position of the punch relative to the blank holder, a floating plate rigidly carrying the punch thereon is made to rest on a floating plate rest as the lower slide descends out of engagement with the floating plate. The floating plate rest is supported by upstanding worms in threaded engagement therewith. A bidirectional electric motor is coupled to the worms via shafting and gearing to cause joint rotation thereof in either direction and, in consequence, the upward or downward displacement of the floating plate rest.

Abstract: An intermittently advanced web of wrapping material is subdivided into discrete blanks which are used in a cigarette packing machine for conversion into portions of soft packs by severing the web across its leader during each interval of dwell of the web so as to separate from the web a discrete blank, and by simultaneously removing one corner at the leading edge of the freshly formed blank. This obviates the need for the provision of triangular notches in the one and/or other marginal portion of the web. Successive blanks are transferred from the severing staton by suction arms for delivery into the range of the converting mechanism.

Abstract: A box-like frame member is formed by deforming the sides of a tubular blank inwardly to provide it with concavely recessed portions in areas corresponding to generally opposing flat surfaces of the product. The deformed blank is expanded, under internally applied fluid pressure, within a sectional die which has its die cavity preferably no more than about 5% larger than the circumference of the blank, to avoid weakening, cracking or yielding of the blank through excessive circumferential expansion.
