  • Patent number: 11084201
    Abstract: Plant for processing plastic preforms, includes an injection-moulding machine for producing the plastic preforms, a sterile blow-moulding machine for forming the plastic preforms into plastic containers, and a transport system for transporting, at least partially and/or in portions, the produced plastic preforms from the injection-moulding machine to the blow-moulding machine, wherein during transport, the plastic preforms can be guided in particular at a mouth region of the plastic preforms. The transport system includes a sterile pneumatic conveyor or a plurality of transport shuttles, in particular magnetic shuttles, and the plastic preforms are transported from the injection-moulding machine to the blow-moulding machine by the sterile pneumatic conveyor or magnetic shuttle.

  • Patent number: 8438966
    Abstract: A device and a piston for segregating articles is being disclosed. The device encompasses a segregating element comprising at least one cylinder with a cylinder housing and a piston installed in the cylinder that has at least one valve. A medium can be fed into and discharged from the cylinder via at least one line. The at least one valve interacts with the at least one line so as to create a hard sealing, and a housing sealing element interacts with a piston sealing element so as to create a hard sealing. The piston can used in a device for segregating liquid containers.

  • Publication number: 20090178296
    Abstract: An apparatus and a method for drying articles are disclosed. The apparatus includes a closed housing with at least one chamber equipped with air nozzles. The apparatus has an inlet opening and an outlet opening for the articles to be dried. An inner routing of air flow inside the housing generates a defined removal of air to the at least one air outlet opening. The inner routing of air flow is designed such that a flow of air is directed past the inlet opening and/or the outlet opening for the articles to be dried.

  • Patent number: 7399435
    Abstract: A process and a device for producing hollow bodies of plastic by stretch-blow molding heated parisons, in which the parisons are inspected before being heated and at least some of the defective parisons are heated and are not separated out until after being heated. This method and the respective device can be implemented at low cost and with low space requirements and it has only a minor negative effect on output of finished hollow bodies.
