<p>1,155,486. Bending glass sheets. LIBBEYOWENS-FORD GLASS CO. 21 Aug., 1967 [22 Aug., 1966], No. 38415/67. Heading C1M. In a machine for bending glass sheets on a ring mould, the mould is accelerated upwardly to engage the mould sufficiently rapidly to cause bending to take place principally by inertial forces. The sheets S are heated at B and conveyed to bending area C and heat tempered at D in known manner. Rolls 28 receive the sheet which is then engaged by bending mould 34 of open ring-type. This engagement is effected by a fluid cylinder 41 and the mould may be vibrated rapidly vertically to apply further inertial forces. A cooling device 56 may be oscillated across the bent sheet and gas jets directed on the sheet from tubular members 58 and 59 to cool it sufficiently to give it rigidity for subsequent movement to the tempering zone D.</p> |
