The present invention relates to an adjustable star wheel and guide rail assembly for use with containers being processed on an automated handling line between machines such as rotary packaging machines. Star wheels derive their name from their general shape. The star wheels of this invention have fingers that support containers, such that they convey the containers as the star wheel rotates. Conveniently, the fingers of the present invention may be set in any position within their range of movement. In addition, a supporting guide rail may be adjusted, for example by rotation on cams. Thus, the fingers and the guide rail may be set to convey containers of varying sizes whilst keeping the container's centres travelling along the centreline of the conveyor.

The invention comprises a rotating transfer machine (40), arranged outside the path (P3) of the die cavities, having a plurality of transfer chambers (50) carried in continuous rotation, each adapted for containing a polymeric body (D) and for transferring it to a cavity of a die (21), and having means for moving the transfer chambers (50) along a same path (P2) so that this path (P2) has a portion (T1) overlapping with the path (P3) of the dies, during which each transfer chamber (50) is vertically aligned and synchronously moving above a corresponding cavity of a die (21), the transfer of the polymeric body (D) to the cavity of the die (21) being carried out in portion (T1). A relatively long path and thereby a correspondingly long time are provided for transferring polymeric bodies from the transfer chambers (50) to the die cavities, for carrying out and effective and correct transfer of the polymeric bodies into the die cavities, starting from a dispensing outlet of the extruder of the polymeric material, also in the case that such body has a relatively large mass.

[PROBLEMS] To continuously, accurately, and rapidly insert forcibly supplied molten synthetic resin lumpy bodies (drops) into a plurality of rotatingly moving compression molding dies when compression molding is continuously performed. [MEANS FOR SOLVING PROBLEMS] In this method and device for continuously supplying the drops for molding a molded product into a rotatingly moving molding female dies, a specified quantity of drops are formed by cutting the molten synthetic resin extruded from an extrusion opening part with a cutter attached to a holding mechanism and the drops are held by a holding mechanism and forcibly inserted into a molding female die recessed part. The holding mechanism on a rotatingly moving type drop supply body is moved close to the rotating molding die to match the rotating route of the holding mechanism with that of the molding die in a specified area to follow up the movement of the holding mechanism to the movement of the molding die.

Ein erstes Formpresswerkzeug (1), welches die Matrize (2) bildet, weist einen Halter (8) auf. Auf diesem Halter (8) wird eine Portion einer zu verpressenden Rohmasse in einem Abstand zum Formpresswerkzeug (1) deponiert. Vor bzw. bei Beginn des Pressvorgangs wird der Halter (8) im ersten Formpresswerkzeug (1) versenkt und gibt die Portion für den Formpressvorgang frei.
摘要:
A method of forming a shaped thermoplastic sheet includes providing a mold apparatus that includes a first mold portion having a contoured and perforated interior mold surface, and a perimeter edge. At least one sheet retainer attaches to the upper surface of a frame the surrounds at least a portion of the first mold portion perimeter edge. Each sheet retainer includes a clamp portion that is positionable relative to the perimeter edge of the first mold portion. With a first portion of a heated thermoplastic sheet retained within the clamp portion a step of the method includes independently, reversibly and laterally moving each sheet retainer, towards and/or away from the perimeter edge of the first mold portion. Sheet retainer positioning allows localized control over the contacting of the interior mold surface and heated thermoplastic sheet thickness which controls the thickness of vanous portions of the final molded article
