Abstract
Equipment for producing a component obtained from two sheets of thermoplastic material joined together includes an upper die, a lower die and a passage for delivering a compressed jet of air between the two sheets. The equipment further includes a slide which can move at right angles to the closure direction of the two dies and has a working sheets are urged against a shaping surface formed by the working surfaces of the upper and lower dies and of the slide by the effect of the delivery of compressed air.

Equipment for producing a component for internal fittings of motor-vehicles, obtained from two sheets of thermoplastic material joined together, the equipment comprising an upper die and a lower die movable relative to each other in a closure direction and means for delivering a jet of compressed air between the two sheets when placed between said upper and lower dies, wherein a slide is movably mounted at right angles to the closure direction of the two dies and has a working surface which connects two working surfaces of the upper die and the lower die to one another, such that, in use, the two sheets are urged against a shaping surface consisting of the working surfaces of the upper and lower dies and of the slide by the effect of the delivery of compressed air, said working surface of said slide having a curvature to define a smooth continuous curved surface with curved surface portion of said dies.
