Title: Improvements in moulding presses
IPC: B29C43/00
Filed: 1965-12-15
Abstract: 1,092,438. Moulding tyres. A. HERBERT and M. GUHR, [trading as LEONH. HERBERT MASCHINENFABRIK]. Dec. 15, 1965 [Dec. 23, 1964], No. 53288/65. Heading B5A. A tyre moulding press comprises a fixed lower press member (1), Fig. 1, not shown, with a fixed mould half (2), and a top press member (3) with a top mould half (4), the top members being lowered towards the lower ones by a poweroperated linkage which includes a pair of links 13 carrying the top members and movable relative thereto. The links 13 have extensions 131 which slide through members 22 secured to member 3, the members 22 bear downwardly on stops carried by the extensions. In order to provide a lost motion between the member 3 and the links 13, 13<1>, and hence the extent of relative movement between the linkage and the member 3 before pressure is applied through the links to urge the mould halves together, a slot 24 is located in each extension and receives a pair of interengaging wedges 25, 26. The latter are movable into and out of the slot to vary the clearance between the upper face of the slot and the upper surface of the upper wedge and hence the magnitude of the lost motion. The wedges are moved by angled levers 33, 41 respectively, pivoted on the member 3 at 21<1>, and having arms 32, 40 connected to the wedges at 31 and 39. A spring (43), Fig. 3, not shown, urges the levers to an initial position in which the wedges are drawn furthest out of the slot. The shorter arms of the levers carry feelers 37 which, when the top press member is lowered, contact adjustable stops 56, 56<1> carried by a column 51 upstanding from the lower press member, whereupon the wedges are moved into the slot until the top mould half contacts the lower one From this position, the links 13, 13<1> move downwards relative the top press member until the tops of the slots 24 bear on the top wedges 25, and a closing force from the linkage is transmitted to the mould halves.

Abstract: 1316478 Skelping YODER CO 10 Nov 1970 [10 Nov 1969] 53437/70 Heading B3E The edges of a strip being formed into a pipe are passed through an edge-forming device 34 having rolls 106, 107, Fig. 5, mounted on plates 98, 99, the plates being coaxially pivotably mounted on a plate 78, Fig. 3, having an aperture 82 through which the strip passes, so that the plates 98, 99 are adjustable relative to each other. In operation the strip is prebent to a shallow dish-shaped cross-section by a roll nut 28, Fig. 9, which includes a vertically adjustable top roll 212 and two sets of oppositely inclined rolls 182, each succeeding roll of each set being inclined with respect to the horizontal to a greater extent than the preceding roll. The two sets of rolls are mounted for movement towards and away from each other so that different widths of strip can be accommodated. After passing through the roll unit 28, the strip is passed through the edge-forming device 34, after which it is passed to a cage roll assembly to be formed into a longitudinally seamed tube. An edge forming device which may be used when the strip is still flat is described with reference to Fig. 11 (not shown) and comprises two sets of relatively adjustable rolls (260, 261) mounted on inclined slides (245, 246), each slide being movable relative to the other.

Title: Continuous forming of transverse stiffening ribs in metal strip material
IPC: B21D13/04
Filed: 1969-11-03
Abstract: 1286133 Corrugating BROWNBUILT Ltd 3 Nov 1969 [16 Oct 1969] 53893/69 Heading B3E A machine for continuously forming transverse ribs 34 in a metal strip 33 comprises feed rolls 6, 7, a die roll 8 having a series of recesses 26 around its peripheral surface, punch rolls 9, 10, 11 arranged in forming engagement with the strip passing over the die roll 8, and a take-off roll 12 in frictional engagement with the formed strip and the die roll, the feed rolls 6, 7 and the take-off roll 12 having a drive arrangement providing a speed differential therebetween so as to reduce tension in the strip as it passes over the die roll. In operation feed roll 6 is engaged with feed roll 7 by rams 25 and take-off roll 12 is engaged against die roll 8 at a relatively high pressure to prevent any slip back of the strip towards the punch rolls. The drive through to roll 7 is by way of a slipping clutch 18 so that the roll 7 is driven slower than the die roll 8 which produces tension in the strip between the nip of roll 6, 7 to the nip between take-off roll 12 and die roll 8. As the strip passes between punch rolls 9, 10, 11 and die roll 8, punch roll 9 partially forms ribs 34 while punch roll 10 completes the rib formation. Punch roll 11 also penetrates the full depth of the rib and assists in reducing pullback of metal from the previously formed ribs. A further roll may engage the strip on the die roll between the punch rolls andthe take-off roll so as to reduce additional friction between the formed strip and the die roll. Lubrication of the strip after it passes the nip between rolls 6, 7 and over punches 27 is provided to prevent galvanize pick-up on the die roll.

The pedestal may be polymeric material eventually removable by dissolving, and may be photoresist material applied by coating, masking and developing. As shown, the height of pedestal 13 is such that the terminals and lands are out of contact initially, a hot gas jet for promoting the fusion also softening the pedestal material and compressing it, allowing the necessary contact. On cooling, the pedestal is restored to its original height, elongating the solder connections and making them more flexible. The pedestal may have projections extending between the terminals, or may comprise a plurality of smaller appropriately located pedestals. In an alternative embodiment (Fig. 5, not shown) the pedestal surrounds the depending terminals and provides an inner edge conforming to the area defined by the exterior edges of the terminals. This pedestal has vents at the corners to allow heated gas to escape, and within it, a solder stop.
