Abstract: 1,112,648. Pneumatic tyres. MICHELIN & CIE (Compagnie Generale Des Etablissements Michelin). 17 Dec., 1965 [18 Dec., 1964], No. 53692/65. Heading B7C. A pneumatic tyre has a breaker of superposed parallel-cord plies, the cords in two adjacent plies making with the same one of the main directions of the tyre (viz. circumferential or transverse direction) opposite angles a and b such that tan (a + b) - 2 tan b is substantially zero and that a parallelogram having its sides parallel to the cords has one of its diagonals parallel to the circumferential or transverse direction and its other diagonal perpendicular to the cords of inclination b, whereby resultants of the stresses developed are substantially perpendicular to the cords and thus shearing is practically eliminated. Tan (a + b) may depart from equality with 2 tan b to the extent which results from a departure from the perpendicular of the second diagonal of not more than 3 degrees or, where the ply edges are bound together, of not more than 10 degrees. In one embodiment the breaker is triangulated and the cords in each adjacent pair of plies have the above relation, suitable cord angles being 18À5, 45 and 71À5 degrees. To prevent relative displacement of the ends of the cords the edges of one ply may be folded over to enclose the edges of other plies; U-section layers may straddle the edges of the plies; or the ply edges may be sewn, welded or cemented together as appropriate. The plies may be asymmetric on each side of the tyre midcircumferential plane.

Drawing is performed in at least three stages. In the first stage the basins are deep drawn upwardly equivalent to 20-25% of their final depth and in the second stage they are deep drawn downwardly by the same tool to 70-75% of their final depth, Figs. 4a, 4b (not shown). The drawn sheet is annealed and the basins are drawn to their final depth by a further tool, which simultaneously corrugates the surface 14. The edges of the sheet are bent to form flanges 18, 20, which are welded at the corners 22 or they may be tapered flush with the surface of the unit at the corners to eliminate welding. The rear edge of the sink unit has a raised rim and vertical flange 16.

As described heat-sealable material from rolls 24, 26 is fed over rollers 76, 78 to form a double thickness web which is then fed via roller 80 to the edge-capping means 82, which comprises a pair of plates 100, 102, Fig. 5 having angled slots 108. The edge or edges of the web, and/or edge-capping strips fed from rolls 40 Fig. 1 are folded by passage through the slots 108, Fig. 5, to provide additional thicknesses of material at the web edge(s). The plates 100, 102 are adjustable laterally by hand screws 106 to cater for different widths of web. The web then passes over rollers 84, 86, Fig. 1, to the heating means 116; 118, Fig. 5, each including heated wires 138 which fuse the thicknesses of web material together. Each heating meads includes plates 128 with tubes 140 for coolant, the plates being mounted on rods 130 interconnected by pinions 132. The pinions can be moved by rams 134 to move the heating elements from the operative positions shown to the inoperative dashed-line positions. The heating elements are adjustable laterally by screws 126.  The web is then folded by passage over rods 66, Fig. 3 and is advanced continuously by a driven capstan 58 to compensating rolls 60 whereafter it is fed intermittently through the rest of the bag-forming machine 54. Should the intermittent feed be interrupted a bar 62 carrying the rollers 60 falls to operate a switch 144 which causes the drive to the capstan 58 to be halted, and sends a signal to a control unit 146 which operates the rams 134 to move the heating elements away from the now stationary web.

A bar 1 carried in the bottom of the channel support 2 has guide grooves 9a, 10a and 9b, 10b for the tapes 5a, 5b, guide grooves 11 for the various pins, such as 12a, and carries the cams 18a &c. The rollers 6a, 6b may be driven manually or by an electric motor (7). In operation, and starting from the condition of Fig. 1 in which both pairs of front and rear curtains are closed, the motor (7) is started and the lugs 16a, 17a engage the pins 12a, 13a of the respective runners 3a, 4a to open the front curtains. On reaching the cams 18a, 19a the lugs 16a, 17a are displaced by riding over the cams and their driving engagement with the pins 12a, 13a is released to leave the front curtains open. Continued operation of the motor effects engagement of lugs 16b. 17b with pins 12b, 15b to displace runners 3b, 4b and open the rear curtains to a position at which the cams 18b, 19b disengage the lugs 17b, 16b.
