Abstract: 965,034. Seaming non-metallic sheet material. OSCAR MAYER & CO. Inc. Aug. 15, 1962, No. 31363/62. Heading B5K [Also in Division B8] Pre-forming webs by vacuum.-A seal between supercooled webs of polyvinylidene chloride formed around a product, is effected by pressure, without heating, and vacuum is used both to cause the lower film to conform to the lower die, and to cause the two films to conform about the product. The machine illustrated seals two such webs about a package of wieners. The lower web 13 (Fig. 1A) is formed to the shape of the lower dies 10 by a vacuum device 75 which moves with each die in turn as the dies are carried along by endless chains 11. The film 13 (Fig. 4) is first pressed against the lower die 10 by a downwardly moving plate 53, which may be provided with sealing gaskets, and is then drawn into the die by vacuum applied to a passage 50 in the die by a nozzle 76 carried by springs on the same carriage 54 as the plate 53. The vacuum is subsequently held in the die by a valve 48 operated by a fixed cam 78. The carriage 54 is moved vertically against the bias of springs 72 by a cam 66 engaging a roller 71 on the carriage. The carriage is also reciprocated horizontally, so that it travels with each die in turn, by a cam 67. The carriage is mounted by rollers 63 to run on tracks (not shown). Vacuum-forming the films around the articles.- When a further, narrower, film 16 has been led above the wieners 15 the films and wieners are enclosed by upper dies 20 carried on endless chains 21 and by side dies 82 (Fig. 9) carried by endless chains 84. The upper and lower and side dies are formed with registering passages through which vacuum, nitrogen and atmosphere can be successively applied under the control of a rotary valve 23 (Fig. 1A) and the valve 48 (Fig. 4) on the lower dies. By this means vacuum is first applied to hold the upper and lower films against their corresponding dies, the space between the films is evacuated and then flushed with nitrogen, and vacuum is applied between the films to form them around the wieners. A serrated fence 41 (Fig. 4) on the lower dies assists in holding the film in place. One of the gas-filled connections between the upper and lower dies is formed by a nozzle 125 (Fig. 12) in the upper die passing through a hole 101 in the side die 82 into a hole 46 in the lower die to form a driving connection so that the lower dies drive the upper and middle dies. In an alternative arrangement (Figs. 24 and 25) the side dies 228 are pivoted to the bottom dies and are swung into and out of operative position by a rack and pinion connection 226, 225 (Fig. 25) with a plunger 222 in the bottom die reciprocated by a roller 224 engaging a cam surface 236, 237, 238 (Fig. 24). Coating dies.-A spring-pressed roller coats the upper dies to prevent the film sticking to them. Specifications 965,031 and 965,032 are referred to.

Abstract: 746,076. Corrugating. KELSEY-HAYES WHEEL CO. Nov. 17, 1953 [Jan. 5, 1953], No 31894/53. Class 83 (4). A rim rolling machine, having opposed rotatable forming rolls movable to and from one another into and out of contact with opposite sides of a wall of an annular rim blank, includes a blank carrier supported to one side of the rolls for movement thereto and from. An annular rim blank B deposited on the receiving end of a shoot 42 depresses a flap 56 in the floor of the shoot to operate a pneumatic valve 55 to cause a piston rod 51 in a pneumatic cylinder 52 to retract a gate 48 in the shoot from the path of travel of the blank, thus permitting it to roll onto a carrier 61. Return of the gate 48 is effected after a predetermined interval through pneumatic valve means actuated by depression of a flap 84 in the shoot 42 as the rim blank leaves. The carrier 61 comprises a sleeve 62 having four radial supporting arms 63 extending therefrom and spaced 90 degrees therearound, 'and is slidable axially on a shaft 60, to present the blank to the forming rolls and to return with the formed rim. The shaft 60 and with it the carrier 61 is rotated 90 degrees at a time by a pawl on a pivoted plate 74, which plate is moved clockwise, to position the pawl, and counterclockwise, to rotate the carrier 61 to discharge a formed rim and accept a blank, by a piston of a pneumatic cylinder means 77 actuated by a valve 80 (not shown) operated by a cam 81 (not shown) on the piston rod 51 of the gate 48. As piston rod of the cylinder 77 approaches its lowermost position a cam thereon operates actuates a valve 99 to cause pneumatic cylinder means 94, linked at 97, 86 to the carrier 61, to move the carrier to the driven rim forming rolls 18, 20. As the carrier 61 approaches its innermost position it operates a valve 103 to cause the lower roll 20 to rise, lifting the blank B off the carrier, and cooperate with the roll 18 to form the blank into a rim. After forming the roll 20 is lowered, to deposit the rim on the carrier 61, and operates a valve 104 (not shown) to cause the cylinder 94 to return the carrier; and with it the formed rim, to actuate a valve 85 to render the valve 55 controlling the shoot gate 48 operative again. Rotation of the carrier 61 during the next cycle deposits the rim on a shoot 110 of an elevator 109. Consequent depression of a flap 118 in the floor of the shoot 110 operates a valve 117 to cause pneumatic cylinder means 114 to lift the elevator 109 into register with a discharge shoot 107 down which the rim rolls, to further rim handling and rolling means, if desired, the elevator 109 being then lowered.
