Abstract: A method for producing a panel comprising at least one region (16) of compression moulded thermoplastic or thermosetting material and at least one region (14) of injection moulded thermoplastic material, comprising the step of placing at least one plate of thermoplastic or thermosetting material in a plastic state between two half-moulds (26, 28) having respective moulding surfaces (30, 32), closing the half-moulds (26, 28) and compressing the plate (16) between two mutually facing compression moulding regions (30a, 32a) of said moulding surfaces (30, 32). The method comprises the step of injecting thermoplastic material into a space defined between two mutually facing injection moulding regions (30b, 32b) of said moulding surfaces (30, 32).

Abstract: An apparatus for moulding an article made of thermosetting and thermoplastic material, including a first and a second half-mould (10, 12) provided with respective compression moulding surfaces (14, 16) above to compress between them one or more plates (30), sandwich or agglomerate, made of mouldable thermosetting material (30), and at least one injection moulding area (18) communicating with at least one of said compression moulding surfaces (14, 16), and spacer means (22) provided in said injection moulding area (18) and positioned in such a way as to prevent said plate (30) from penetrating into said injection moulding area (18) when it is compressed between said compression moulding surfaces (14, 16).

Abstract: A process for the hot moulding of articles (L) made of thermoplastic material includes the steps of: heating at least one plate of thermoplastic material (L) to a plasticizing temperature; compressing the heated plate (L) between two moulding surfaces (14, 16), set opposite one another, of a pair of half-moulds (10, 12); and forming, by injection moulding, at least one component (22) anchored to a surface of the plate (L), while the plate is being compressed between the moulding surfaces (14, 16).

Abstract: A box of plastics material, comprising a bottom wall (22) having a rectangular shape, from which a pair of longer lateral walls (28) and a pair of shorter lateral walls (24, 6) project. The box comprises a first and a second pair of support elements, in which the support elements of the first pair are arranged along a first lateral wall (24) and the support elements of the second pair are arranged along respective lateral walls (28) orthogonal with respect to the first wall. The support elements are arranged so that the box can be interpenetrated with a box of the same type when the two boxes have the same relative orientation and can be superimposed to a box of the same type when the two boxes have an opposite relative orientation.

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.

Abstract: The equipment comprises a molding element (16) having a working surface (18) against which a previously-heated sheet (12) of thermoplastic material is urged. The equipment comprises at least one movable element for defining a cavity (38) with an undercut cross section which, in use, encloses a portion of the sheet (12) to be molded and compressed-air supply means (36) which brings about the deformation of at least one portion of the sheet (12) by means of a jet of compressed air.

Abstract: The box includes a sheet of moulded plastics material with a central portion constituting the base of the box and four foldable flaps which are hinged to the central portion form the side walls of the box. The foldable flaps are interconnected by corner uprights each of which includes a central rib and two rows of segments which constitute the opposed walls of a pair of channels for housing the side edges of the flaps. The segments in each row are separated by spaces the heights of which, along the longitudinal axis of the rib, are equal to or greater than the heights of the segments in the opposite row, along the same axis. The segments in each row face the spaces between the segments in the opposite row.

Abstract: This invention relates to a mold for the covering and trimming of plastics products, particularly of panels for the inside upholstery of motor vehicles. The object of the invention is to avoid that the covering material (4), spread over a heated sheet of plastics material intended to constitute the product (3) to be covered, may be pinched between two side knives (8) associated with two substantially rectilinear sides of the outline of the product (3) and converging to each other toward a preferably rounded corner of said product (3). To achieve this object, at the angle between the two side knives (8) associated with the converging substantially rectilinear sides, there is arranged a knife (8') which is shaped correspondingly to said corner, and the ends of which slidably engage the outer planar surfaces of tapered end extensions (108) of the side knives (8). Means (9, 9', 10, 10') are provided for displacing simultaneously the side knives (8) and interposed shaped knife (8').

Abstract: Shaped and self-supporting stratiform laminates, such as inner door panels for automobiles, are produced from a thermoplastic substrate and a flexible sheet material in a one-stroke molding, laminating, and cutting operation; laminated products obtained have protruding free edge portions of the flexible coating sheet so that cut edge portions of substrate can be covered subsequently with the protruding free portions.Apparatus for producing such laminates is a molding press having two molding plates, each of which includes one component of a pair of cutting means; the other two components of the pair of cutting means are provided by a generally annular element that is movable relative to the molding plates; the annular element includes a surface for cooperation with a peripheral knife around the surface of the upper molding plate to form one cutting means, and a cutting edge for cooperation with a shearing edge of the lower molding plate to form the second cutting means.
