Abstract:
A system (10) for forming glass sheets includes a glass location sensing assembly (80) having a fluid switch (82) that is actuated by a roller conveyed glass sheet (G) to control operation of transfer apparatus (69) that transfers the glass sheet from the roller conveyor (22) to a forming mold (48) at a design position for forming. A frame of the sensing assembly (80) supports a carriage (124) on which the fluid switch (82) is mounted for lateral movement with respect to the direction of conveyance of the glass sheet (G) so as to sense its leading extremity. A lateral positioner (130) adjusts the lateral position of the carriage (124) and the fluid switch (82) mounted on the carriage.

Abstract:
An bent glass sheet producing apparatus (20) has a heating furnace (21) in a heating zone (Z1), a preliminary forming mechanism (25) in a preliminary forming zone (Z2) downstream of the heating zone (Z1), a two-directional bending mechanism (30) and a conveyor roller mechanism (40) in a forming zone (Z3) downstream of the preliminary forming zone (Z2), and a cooling mechanism (50) in a cooling zone (Z4) downstream of the forming zone (Z3). For a purpose of conveying a two-directionally bent glass sheet formed by the two-directional bending mechanism, the conveyor roller mechanism (40) includes a plurality of conveyor rollers (41) having an arcuate shape of a radius (R2) in a direction perpendicular to the conveyance direction of the glass sheet, the conveyor rollers (41) being arranged on an arcuate line having a radius in the conveyance direction.
Abstract:
The invention relates to a contact member or covering (1) for covering structures (4, 9) that come into contact with glass objects (12) during their forming process. The covering is a relatively compact non woven fiber web (2) with apertures (10) and comprised of randomly oriented fibers which are composed, for example, of stainless steel. This covering can for example be used to cover tempering and pressure rings which are used in the process of forming glass plates.
Abstract:
The invention relates to the method for manufacturing tempered glass by static-pressure lifting, which includes making heated glass closely adjacent to the negative pressure mold which is able to raise and lower in the shaping chamber; the glass was drawn against the negative pressure mold under the action of the negative pressure after a negative pressure was applied; the negative pressure mold was raised together with the glass, then a transfer mold moved into the shaping chamber and located therein; the glass was loaded onto the transfer mold by its own weight after the negative pressure was released and then transferred to blast heads for cooling with air. Therefore, there is only negative pressure formed but without the flow of gases during the whole overall process. The process, hence, is easy to operate, with lower unit consumption and cost, and the product is of high quality.
