Abstract
PURPOSE: To obtain a deeply-drawn vessel having a large ratio of its depth to its bore in the same way as a thick sheet is used, by putting thin polypropylene sheets in layers, and heating the layered sheets to a forming temperature while forming them.
CONSTITUTION: The first sheet 3 is mounted from the first sheet feeder 1 onto a lower conveyer belt 2, and then the second sheet 5 is mounted from the second sheet feeder 4 onto the first sheet 3. These sheets are clamped between upper and lower conveyer belts 6, 2, carried into a space between upper and lower hot-pressing plates 8, 9, and pressed. The layered sheets carried onto a female die 12 through a sheet transfer 10 and an air cylinder 11, after its part expected to be the flange of a vessel is forged by the descent of an auxiliary die 13, is deeply drawn by the descent of a plug 14 and compressed air. As the sheet material is used a crystalline polyolefin sheet or a multi-layered one involving the said material sheet on at least its one surface.
