摘要： In the moulding of composite plastic material, in particular of foamed polystyrene coupled with rigid polystyrene sheet, the rigid material (2) is preformed, with the preformed portion being simultaneously separated from the starting material, and the preformed shaped portion is transferred to the preforming half-mould at the moulding step, in which the formed material is moulded by means of sintering and pulsed steam action on the preformed rigid material. The resulting piece is brought back to the preforming step (1) and a further portion of rigid material (2) is preformed on the foamed material, and this portion is then thermoset inside the moulding mould (3) on the foamed material, thus generating an article with two opposite surfaces made of a rigid material, between which the foamed material is sandwiched.

摘要： This invention relates to a mold for the covering and trimming of plastics products, particularly of panels for the inside upholtery 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, ther 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'). The sliding surfaces between the extensions (108) of the side knives (8) and interposed shaped knife (8') are at such an angle to the directions of movement of either the two side knives (8) and the interposed shaped knife (8') as to always remain in contact with each other during the movement of said knives.

摘要： Method and device for sealing thermoplastic material. A support plate (16) supports sheets (29, 31) of the thermoplastic material, and a heat element (18) is provided adjacent thereto. A pressure plate (20) mates with the support plate and includes recess means (24) for receiving the heat element means. A confined melt zone (35) is formed between the heat element and the pressure plate (or the recess means) when they are in mating relationship. The confined melt zone serves to confine the melted thermoplastic material to form a good seal by relieving stress between the seal and the seal-material interface. The heat element and recess means are manufactured as interchangeable dies in different sizes and shapes for different materials. The heat element may be formed into different shapes, such as a glove for manufacturing gloves.

摘要： Apparatus for longitudinally and transversely trimming articles (CII), C(II)) moldingly formed on plastic sheet (b) which is brought by means of a pair of clamp chains (10) between longitudinally movable pointed tip knives (51) and longitudinally extended holder members (61) as well as transversely movable pointed tip knives (31) and transversely extended holder member (41) respectively held in retracted position and then trimmed by moving said knives and holder members to forwarded position and by moving said knives. Said sheet (b) is formed in advance with transversely and longitudinally extended ridges (XR, YR) so that said moving knives cannot sever the sheet at said ridges, whereby trimmed articles fall down by gravity and waste portion kept in one piece is brought out by said clamp chains to be collected. In order to attain correct trimming, said sheet (b) is formed in advance further with additional transversely and longitudinally extended ridges (XR, XR 2 , YR, YR', YR") respectively beside and in parallel with lines to be severed so that each rib (310, 510) mounted beside the concerned knife (31, 51) and extended in parallel with the knife moving direction fits in the concerned additional ridge of the sheet from the reverse side.

摘要： Bei dem Herstellverfahren wird Platten- oder Bandmaterial (19) aus thermoplastischem Kunststoff in einer im wesentlichen zweiteiligen Streckform (1) durch Einblasen von Heißluft zu einerAbdeckwanne mit Stehrand umgeformt und der allseitig überstehende Randstreifen bereits beim Schließen ihrer Formhälften (3, 4) abgetrennt.
Eine erste Formhälfte (3) ist hierfür mit einer Schnittplatte (7) ausgerüstet, welche an einer Grundplatte (5) befestigt ist. Die Schnittplatte (7) weist eine dem Umriß des zu formenden Stehrandes entsprechende äußere Begrenzung auf, wobei ihre freie Außenkante eine Schneidkante (9) bildet. Die Schneidkante (26) der zweiten Formhälfte (4) besteht aus einer dem Umriß des Stehrandes entsprechenden Innenkante der eingefahrenen Schieber (15) des Formennestes (14). Das Dickenmaß der Schieber (15) übersteigt die Höhe des zu formenden Stehrandes und um dieses Maß sind die Schieber (15) mit ihren Schneidkanten (26) an der komplementären Schneidkante (9) vorbei über die Schnittplatte (7) absenkbar.
Die Schnittplatte (7) trägt zudem eine Klemmplatte (12), deren Außenseite um das Dickenmaß des zu formenden Stehrandes der Abdeckwanne nach innen hinter die Schneidkante (9) der Schnittplatte (7) zurückgesetzt ist.
