发明名称 Machine for the continuous production of concave shells from webs of reinforced thermosetting plastic material or thermoplastic material
摘要 The machine comprises a rotating mould (1), a countermould (2) formed by flexible endless elements running over rollers. The element to be moulded (3) passes in the plastic state between the mould (1) and the countermould (2), thus assuming the shape of the mould (1). A heating or cooling tube bundle (4) for hardening the moulded element and a chain saw (12) for cutting the moulded element to the desired format are provided. The machine can be used for manufacturing translucent or opaque products for use in agriculture. <IMAGE>
