Abstract

The injection pumps in a piping circuit ending in nozzles by which plastic materials are delivered, are regulated before the injection is started, so that precompression is applied to the materials. The filling of the injection pumps before any compression is effected at a pressure lower than the lowest of the injection pressures likely to be used. The degree of precompression is pref. at most equal to the injection pressure prevailing when conditions are stabilised. Used for the prodn. of multiple glazing sealed externally by a plastic material. The process consists of placing on the whole of the perimeter of a first sheet of glass a spacer in the form of a frame, placing a second sheet of glass is placed on the spacer, and filling the cavity between the edges of the sheets of glass and the frame in succession along each side of the glazing. The irregular feed at the commencement of the operation according to known techniques, causing considerable wastage of material and bad sealing, is rectified.
