Manufacture of a strand of organic material serving as a joint and distance keeper in multiple glazing.

摘要

The invention relates to the manufacture of a strand of organic material intended to serve as a seal and distance keeper in multiple glazing. …It proposes a method consisting in pumping raw organic material of high viscosity, greater than 35000 poises, in conducting this pumped material to an outlet nozzle in immediate proximity to which is provided a compression/decompression unit, and in inserting on the line conveying the material to the outlet nozzle a lock limited by inlet and outlet valves and in which the pressure is preferably regulated. …It also proposes an installation with a pressure-regulated lock. …It makes it possible to provide a strand for forming a distance- keeping seal for multiple glazing with high regularity. ……
