Abstract

881,703. Vacuum-moulding machines. SHELLEY & PARTNERS Ltd., M. L. Aug. 26, 1960 [Aug. 26, 1959], No. 29170/59. Class 87(2). In a vacuum-moulding machine the thermoplastic sheet 6 is clamped against the vacuum box 2 magnetically. As shown in Fig. 1, either the clamping frame 7 or the box 2 or lugs on either of these parts are permanently magnetized. In a modification, Fig. 3, the frame 7 is closed by a solenoid 19 through a linkage 9, 10 and 13 locked in the closed position by further solenoids 23 causing hooked armatures 22 to engage lugs 21. In a further modification, Fig. 4, the frame is pivoted at 25, and is opened by a solenoid 26 and closed by a solenoid 30. The movement of the frame may be mitrated by movement of a heater hood 8 or by a timing device which controls the operation of the machine.
