IPC: B29D30/36
Filed: 1942-05-30
Abstract: 562,712. Shaping flat-built tyre bands into tyre form. STEVENS, A. H., (Firestone Tire & Rubber Co.). May 30, 1942, No. 7357. [Class 87 (ii)] Apparatus for shaping a flat-built tyre band into tyre form comprises a stationary upper head 66, a movable lower head 35 mounted on a hydraulic ram 28, means for injecting pressure air into the interior of the tyre band whilst it is being shaped, and means for feeding an expansible core 61 through an aperture in the upper head into the tyre band. The lower head 35 is separate from the ram, being carried by an electricallyreciprocated platen 34 which runs on rails which are aligned with other rails on the ram cap 30. Operation :-(1) A core 61 is hung on a hook 70, collapsed, by evacuation of air therefrom and drawn up into a cylinder 65 in the upper head by an electric motor 85. (2) The operator mounts a tyre band 60 upon the head 35, and operates motor 46 to feed platen 34 with head 35 on to the ram cap. (3) Ram 28 rises, the band 60 is compressed, and pressure air is admitted to the cylinder 65, whence it passes to the interior of the band 60. (4) The air pressure in the band is decreased from 75 to 40 lbs./sq. inch, the ram is lowered a little, and motor 85 is operated to lower the hook and core into the band. As the core descends, carbon dioxide under pressure is admitted thereinto. A deflector 37 on the head 35 directs the core laterally into the (curved) band. (5) The ram is raised to its original position, the pressure in the band is raised to 75 Ibs./sq. inch, the pressure in the core is increased, and then, to prevent wrinkles forming in the core, the pressures in the core and tyre band are alternately lowered and raised, the pressure in the core being maintained slightly greater than that in the band. The drops in pressure are greater than the the pressure in the cylinder 65, i.e. in the band, being finally atmospheric so that the heads can be separated from the band. (6) The core is evacuated, the tyre band vented to atmosphere, the rain is lowered, and the motor 46 retracts platen 34. Specifications 419,244 and 562,875 are referred to.
