Abstract:
A method and device of forming a slab (1) having at least one profiled edge comprising a base sheet (2) and a cover sheet (3) connected herewith, the cover sheet being partly connected with the base sheet in a manner such that a peripheral part (4) of the cover sheet protrudes beyond the edge of the base sheet, in the proximity of which the profiled edge has to be formed, comprising positioning of the base sheet with the cover plate partly connected herewith with respect to a mould (8) having the profile of the profiled edge and nestling an outer surface of the peripheral part of the cover sheet against the mould, filling out a space bounded by the peripheral part of the cover sheet and the edge of the base sheet with curable filling means (12) adhering to the two sheets, curing of the filling agent and removing the slab from the mould.
Abstract:
Mold structure for forming a polymeric gasket around a predetermined portion of a sheet of transparent material such as glass, with the object of minimizing hand labor in the assemblying of seals and windows. The mold structure includes two cooperating mold sections (12 and 14) for defining a chamber for receiving the transparent sheet (16). A seal (18, 20) is positioned about the periphery of the chamber and is utilized to resiliently support the sheet within the chamber. Also, the seal cooperates with a predetermined portion of the transparent sheet for defining a gasket cavity having a configuration corresponding to the gasket to be formed on the sheet of transparent material. An inlet (25) communicates with the gasket cavity and is utilized to introduce a flowable gasket material into the gasket cavity.
Abstract:
A method and a means for the manufacture of a wheel construction (2) of plastic material for vehicles or similar, which comprises a number of spokes (2A-2H), a hub (2J) and a rim (2I) together constituting an integrated unit. By means of the invention it is made possible to manufacture a wheel construction, the strength property of which is high. The plastic material is injected in a mould (1), the cavity (7) of which exhibits a form corresponding to the one of the desired wheel construction, the design of the wheel being chosen to comprise an even number of spokes (2A-2H). The inlets (3-6) are located at such points near to every second one of the spoke portions (2A-2H) forming part of said mould (1), that the zones (7'), where the flows of material join each other, will be located near to points, where the spoke portions (2B, 2D, 2F, 2H), free from inlets, blend into the rim (2I).
