BENDING FURNACE FOR GLAZINGS

摘要

A bending furnace for glazings comprises several heating cells, a station for bending by pressing, at least one cooling cell and a system for intermittent transport of glazings. The glazings are laid on bending rings (2), mounted on mobile carriages (3), coupled to one another in a train. The train is pulled by a pulling machine installed at the end of the furnace and outside the latter. The point of application of the pulling machine which moves carriages (3) and the length of the travel of this pulling machine are controlled as a function of the temperature to take into account the variation of length of the train. The precise positioning of the carriage in the pressing station is obtained by a detector (27) joined to pivoting stops (28, 36).
