  • Patent number: 8157556
    Abstract: A system for controlling the dimensions of an extrudate exiting an extruder and for compensating for the variations in the extrusion rate of the extruder, expansion rate and rate of travel of the extrudate through sizing devices by changing the speed of an extrudate puller device, includes an extruder which extrudes the extrudate; a conveyor system comprising rollers and a series of sizing devices; a puller device for pulling the extrudate through the sizing devices; and a laser proximity measuring device to assist the system in keeping the desired shape of the extrudate. The laser proximity measuring device includes at least one pair of optical non-contact displacement transducers, a real time processor, and an interactive touch screen display unit. The transducers emit a laser beam which provides a laser point on the side of the extrudate.

  • Publication number: 20120088006
    Abstract: A coating die having a shut-off bar positioned to stop the flow of coating material within the flow channel of the die when the shut-off bar is in the closed position. In the closed position, the shut-off bar extends across the material flow channel, blocking flow of coating material therethrough. The shut-off bar moves essentially orthogonal to the direction of material flow. In some embodiments, the flow channel includes a shoulder against which the shut-off bar physically seals, the seal being essentially transverse or orthogonal to the direction of the material flow channel. Coating dies having a shut-off bar are particularly suited for patch coating applications.

  • Patent number: 8113810
    Abstract: An extrusion die assembly includes a hollow extrusion head which has a head inner surface, a central passage inlet opening, a forming section having a die opening, and a receiving space that extends from the central passage inlet opening to the forming section. A flow-dividing core is disposed within the receiving space, and has a central passage connected to the central passage inlet opening and extending to the forming section, and a grooved outer surface that is disposed upstream of the forming section and that has at least one groove which cooperates with the head inner surface to define at least one accumulating passage. An annular passage is formed in the forming section and around the flow-dividing core and the central passage, is connected to the accumulating passage, and merges with the central passage in the die opening.

  • Publication number: 20110285051
    Abstract: The invention relates to an extrusion line for producing plastic profiles, preferably plastic tubes, comprising at least one extruder (1), a tool (2), a calibrator (3) and additional subsequent devices (4, 5). According to the invention, for cooling the profile (9), the tool (2) has a recess and/or a chamber (11) is arranged about the extruded pipe in order to be able to change the air counter to the direction of extrusion (7). The invention also relates to a method for extruding a plastic profile, in particular a plastic tube, in an energy-efficient manner, said method consisting of the following steps: a) the plastic is melted in an extruder (1); b) a plastic strand is formed and is fed to a tool (2); c) a plastic profile is formed by means of the tool (2) and d) the profile is calibrated and hardened by cooling in a calibrator (3). The profile (9) is externally cooled as well as internally cooled in the calibrator (3).
