Abstract

1,105,831. Sheet delivering apparatus. PARNALL & SONS Ltd. 9 Aug., 1965 [11 Aug., 1964], No. 32591/64. Heading B6H. Apparatus for pressure forming of thermoplastic sheets comprises two reciprocating moulds 9, 10 on to which are positioned sheets of material which when deformed by a movable platen 5 at an operating station 11 are moved alternately to respective stacking stations 13, 12 by air cylinders 8. At the stacking stations further air cylinders 15 displace the moulds and the sheets mounted thereon into stacking frame 16, which is provided with sheet retaining means which hold frictionally the deformed sheet and the mould is returned downwardly and then displaced into the operating station.
