Abstract

867,928. Vacuum-moulding thermoplastic sheet materials. TOLUZZO, H. P. Aug. 11, 1959 [Aug. 14, 1958], No. 27448/59. Class 87(2). A toy device for vacuum-moulding thermoplastic sheet material comprises an open-topped container 2 which has hinged thereto an airtight clamping frame 16 and a heater 20, said container being connected to a vacuum pump 12 and enclosing a plate 3 which supports the moulding pattern (not shown). A sheet of thermoplastic material is clamped over container 2 against packing 19 by frame 16 and heater 20 is pulled down over the sheet. When the sheet is at the desired temperature the heater is raised, plate 3 raised by lever 5 so that the pattern is pressed against the sheet, and air is extracted from container 2 through holes 4 by pump 12. The plate 3 is raised by a system of spindles and levers, fig. 3 (not shown), and the container may for instance be of circular cross-section, Figs. 5-7 (not shown).
