    摘要: In an apparatus for producing hollow bodies from thermoplastic material in large numbers a plurality of stations in which the blanks are successively subjected to various treatment steps are arranged at horizontal spacings around the peripheral surface of a vertical, substantially cylindrical housing of an operating unit of the apparatus. The blanks to be treated are passed downwardly through the operating unit and a first one of the treatment stations therein to the next station therein. Arranged within the operating unit is a cam drum which rotates about a vertical axis and which has cams adapted to actuate tools for treating the blanks in at least some of the treatment stations. Two or more such operating units may be connected in succession for carrying out successive treatment operations on the blanks.

    摘要: A process for producing hollow bodies from oriented thermoplastic material wherein a cylindrical portion of a heated hollow preform which has a bottom thereon is subjected to stretching at a starting temperature which is below the vitreous transition temperature of the thermoplastic material, with the wall thickness of the preform being reduced in the stretching operation. Prior to the stretching operation the preform is heated in the portion in which the stretching effect begins, to a temperature higher than in the portion adjoining same. Stretching is preferably effected along the axis of the preform at different rates such that in the portion of the preform at which stretching begins, stretching is effected at a lower rate than in the portion adjoining same in the stretching direction.

    摘要: An apparatus for treating blanks of plastic material comprising a substantially cylindrical main frame structure, a central, coaxial cam drum which is mounted within same rotatably about its longitudinal axis and which is provided on its outside with working cams, and a plurality of treatment stations arranged in juxtaposed relationship around the periphery of the frame structure, with tools for processing the plastic blanks. The tools in a respective station are carried by vertically movable carriages, each of which is adapted to be moved up and down in the station by a cam follower guided by an associated cam on the cam drum. Each cam follower is carried by a drive carriage. The respectively associated tool carriages and drive carriages are each independently guided on the housing by vertical guide means and are interconnected by way of non-rigid connecting means. The guide means for the carriages are arranged in projection on to a plane perpendicularly to the direction of movement of the respective carriage, between the cam follower and the point at which a reaction force resulting from treatment of a said blank acts on the tool carriage.

    摘要: In the production of hollow bodies from oriented thermoplastic material, a cylindrical portion of a heated hollow preform is stretched, with a simultaneous reduction in the wall thickness thereof, at a starting temperature below the vitreous transition temperature of the material. A mandrel is positioned in the preform to support it during stretching, the outside diameter of the mandrel corresponding to the inside diameter of the preform. Directly before the mandrel is inserted into the preform the preform is subjected to re-alignment to adapt at least the cross-sectional shape of the mouth opening of the preform to the cross-section of the mandrel. The re-aligning operation is effected by inserting the preform into a sleeve adjoining a drawing ring for carrying out the stretching operation.

    摘要: In the art of blow molding thermoplastic articles a pair of blow mold halves is closed around a parison. A blowing medium is applied so that the parison is thus blown to a container configuration. In this blowing step very high closing forces are necessary to maintain the mold halves in closed position. The invention provides for a plurality of biased pistons which are actuated by a pressure medium to support the mold halves on a stationary frame.

    摘要: This device is used for the blow moulding of thermoplastic synthetic material, with it having a blow mould consisting of at least two blow-moulding elements. The blow mould is provided with an internal space designed for shaping a produced container. The blow moulding elements are arranged in the region of pivotally seated mould carriers. The mould carriers are guided on a shaft and a locking device is provided in the area of the end of the mould carrier facing away from the shaft. In the region of their extension facing away from the locking device, the mould carriers project beyond the shaft by means of their actuating arms. The actuating arms are rotationally coupled to an adjusting element via coupling levers. The adjusting element is guided essentially in the direction of a center line of the blow mould.
