    摘要: A method of reducing wastage during the start-up phase of an extrusion device used to produce extruded profiles such as tread strips for vehicle tires from a plurality of mixtures is disclosed. The extrusion device comprises a plurality of extruders each extruding a component of the profile and each extruder has its own drive means. The outlets from the extruders communicate with a template member having flow channels formed therein which lead into a common extrusion port. The drive means are actuated simultaneously and the pressure of each of the components is monitored in the outlet region of each extruder. These pressures are compared with a pre-determined desired pressure by a control device, which device switches-off the appropriate drive means as each desired pressure is attained. When all desired pressures have been attained, all of the drive means are re-actuated simultaneously by the control device. In a minor modification of the method, the drive means for the final extruder to reach its desired pressure is not switched-off and the other drive means are simultaneously re-actuated when the final desired pressure is attained.

    摘要: In a screw extrusion device used for extruding plastics materials, a filter or tool-carrier is disposed at the downstream or outlet end of the extruder, an annular pressure element bearing on the carrier so as to secure and seal the carrier in its operative position. The carrier is displaceable perpendicularly to the flowpath of the plastics material so as to permit facile changing of the filter element. The annular pressure element is acted upon by hydraulic fluid, the hydraulic circuit including an annular pressure chamber. The inner and outer walls of the chamber are formed, respectively, by concentric metal bellows. One end of each bellows is mounted on the pressure element and the other end thereof on a housing.

    摘要: An apparatus for reducing wastage during the start-up phase of extrusion device used to produce extruded profiles such as tread strips for vehicle tires from a plurality of mixtures. Each of a plurality of extruders extrudes one component of the profile and is provided with its own drive motor. The outlets from the extruders communicate with a template member having flow channels formed therein which communicate with the outlet ends of the extruders and which lead into a common extrusion port. Pressure sensors are positioned adjacent to the outlet of each extruder. These pressure sensors and the drive motors for each extruder are operatively connected to a control device which has stored therein predetermined desired pressure levels for each extruder. The drive motors for the several extruders are actuated and the pressure of each is monitored and compared with the predetermined desired pressure for each extruder. When the pressure in a particular extruder reaches such desired pressure, the drive motor for that extruder is shut off. When the desired pressures have been reached in all of the extruders, the drive motor for all extruders are re-actuated simultaneously by the control device. Alternatively, the last extruder to reach the desired pressure can continue to operate and the drive motors for the other extruders re-actuated. In either event, wastage of material is greatly reduced.

    摘要: An extrusion head for producing, for example, tread strips for vehicle tires comprises a stationary central portion and two pivotable outer portions. Between each outer portion and the central portion, in the operative position of the head, insert members are interposed. Flow channels for the different materials used to make the tread strip and defined between the insert members and the central and outer portions of the head. The insert members are made displaceable by being detachably affixed to push-rods which are hydraulically, pneumatically or mechanically actuated. This provides for movement of the insert members, when the outer portions are pivoted away from the central portion, into a position which permits unhindered access to all sides of the insert members and permits the rapid cleaning and/or replacement thereof.

    摘要: An extrusion head for producing flat profiles such as tread strips for automotive vehicles from three or more different rubber or plastics materials is disclosed. The head comprises a fixed central portion and upper and lower portions pivotally connected thereto, and is fed with the different mixtures by a plurality of screw or worm extrusion devices. Between the upper and central portion and the central and lower portions of the head, insert members are located. In the upper and/or lower surface of each insert member, flow channels for the mixtures are defined, the flow channels each being bounded upwardly or downwardly as appropriate, by a plane surface of one of the portions of the head. The insert members are axially divided and are made in one piece. The flow channels each have a longitudinal axis of symmetry and such axes lie in a common vertical plane. Such an arrangement permits the profile to be changed merely by replacing one or both insert members, permits the worms or screws to be readily removed for cleaning purposes and also ensures that the flow rates in each of the flow channels is substantially constant, thereby avoiding problems of pre-vulcanization.
