ABSTRACT:
The bending machine adapted for production of foamed decoration articles of doors and windows is provided with a round upper mold and a round lower mold. The former has a central through hole equipped with a retaining member. A hydraulically operated presser is placed above the round upper mold so as to permit the upper mold to move up and down and to spin. The latter has a peripheral flange on a specific section of the upper face and the lower end is equipped with a spinning transmission mechanism to drive the lower mold. At one side and at a distance from the lower mold is disposed a positioning push rod which is engaged with a pneumatically operated device driving the positioning push rod to move back and forth. At the front of the lower mold and the positioning push rod is placed a retaining mount having a housing groove. Besides, the guide groove of the positioning push rod and the housing groove of the retaining mount are parallel and lie flush with the lower mold whereby the foamed decoration articles can be processed in a ready and speedy manner to produce flat and smooth decoration articles.
