Abstract:
A method for the manufacture of an aluminum profile having a resin sheet material integrally laminated thereon and an apparatus to be used therefor are provided. A coated aluminum profile is subjected to the surface modification by means of a corona discharge treatment unit. Preferably, a surface portion of the aluminum profile on which an edge portion of the sheet material is to be laminated is further subjected to a local electric discharge treatment by means of a local electric discharge treatment unit. Then, a sheet material is continuously laminated on a plurality of aluminum profiles being conveyed, and thereafter the sheet material is cut at a position between the aluminum profiles by means of an electric discharge cutting device to form the sheet-laminated aluminum profile.
Abstract:
The sheets (1) and (2) are cut separately in rectangular shapes and with one of their corners recessed (1.2) and (2.4) and the sheet (1) slightly larger than the other one, double, on layer (2.1) an alignment of cylindrical lenses (2.2) which reflect images from the other internal sub-sheet (2.3), the two sheets (1) and (2) are superimposed; they are joined and their rims hooked together, in a tube (3) with the vertical upper recesses; a small flange (1.3) is configured at the top covering the rim of the sheet (2), except for the recess thereof, with one of the ends of the small flange (1.3) overlapping the other; the lip (1.4) is inserted in the stepped piece (4.1) of the bottom (4) of the container; the latter is flanged (4.2).
Abstract:
A can bottom having an approximately frustoconical portion extending downwardly and inwardly from the can side wall, an annular nose portion extending downwardly from the approximately frustoconical portion, and a central portion extending upwardly and inwardly from the nose. The nose is formed by inner and outer circumferentially extending frustoconical walls that are joined by a downwardly convex arcuate portion. The inner surface of the arcuate portion of the nose has a radius of curvature adjacent the nose inner wall of at least 0.060 inch. The central portion of the can bottom has a substantially flat disc-shaped central section, having a diameter of at least about 1.40 inches, and an approximately dome-shaped and downwardly concave having a radius of curvature no greater than 1.475 inches. In a preferred embodiment of the invention, the inner surface of the arcuate portion of the nose is formed by a sector of a circle and has radius of curvature is no greater than about 0.070 inch. An apparatus for making the can bottom comprises a nose punch whose distal end has a radius of curvature that is equal to the radius of curvature of the can bottom nose and a die whose radius of curvature equals that of the dome.
Abstract:
A flexible bushing for a cam follower, comprising a substantially rigid inner sleeve including an inner cam follower engaging surface, a length of the inner sleeve being greater than a thickness of a ram into which the flexible bushing is inserted, a substantially rigid outer sleeve including an outer ram engaging surface, a length of the outer sleeve being substantially equal to the thickness of the ram, the inner and outer sleeves being substantially concentric, and a shock absorbing flexible material disposed between the inner and outer sleeves.
Abstract:
The invention relates to a method for the production of a rolled edge from an edge section (11) of a tube, wherein a flanging die is driven onto the edge section and flanges it into a roll. According to the invention, an initial area (14) of the edge section (11) is previously rolled in a positive fit manner by means of a forcibly controlled tool (30). This prevents buckling of the initial area (14), which has a controlled geometry as a result of rolling. The novel method is preferably used in the production of valve seats in so-called aerosol domes (10) for spray cans.
Abstract:
A manually operable rigid device defines a generally V-shaped groove opening onto an outer face thereof for closing a storage container in a multi-step process by bending a flexible, upstanding peripheral rim thereof over a margin of a central cover. A manually operable rigid device defines a wedge having a tip for opening a storage container in a multi-step process by unbending the previously bent rim thereof.
Abstract:
For the manufacture of a ring part out of a flat sheet-metal part to form a lid for a lid of a can. A hot-sealable coating is provided on one side of the sheet-metal part which is then shaped into a cylindrical tube with the coating being on the inside. The axially extending edges of the tube are joined together to form a butt-joint and the inside surface thereof pressed against a cooling plate. A butt-joint welding seam is then created by means of a laser jet. The tube is separated into equal length tube sections and each is conically enlarged at one end. The other end of each tube section is bent radially inwardly to form a bearing surface for a tear-off foil. By flanging the conically enlarged end, an annular flange is created to receive a body of a can.
Abstract:
A seam adjuster for ensuring that a tight seam is formed between a can end and a can body. The seam tool (32) is mounted via bearing (34) on the seam lever (31), the centre of the bearing being eccentric to its outside diameter. The bearing has an-external thread (35) which mates with a complementary worm mechanism (36). By virtue of the eccentricity, rotation of the worm mechanism rotates the bearing and moves the seam tool radially for adjusting seam tightness. Seam tool height is set by a spacer (33) or shim which is readily interchangeable for varying the seam tool height without affecting seam tool tightness.

Abstract:
A system for performing sequential operations on a can body, such as necking the open end of the can body, in which two or more machines, such as die necking machines are, are coupled by a transfer module. The transfer module comprises a multi-pocket wheel that receives can bodies from a multi-pocket discharge wheel of the first necking machine and discharges them to a multi-pocket input wheel of the second die necking machine. The drive motor of one of the necking machines is eliminated, while the drive motor on the other machine is enlarged. A gear on the transfer module couples the gear trains on the first and second necking machines into a common gear train. Thus, the transfer module gear train transfers power from the necking machine having the enlarged drive motor to the necking machine for which the drive motor was eliminated. This enables a single drive motor to entire drive train for both machines.
