    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.

    The invention relates to the processing of polymers in the product and can be used for the manufacture of various rubber compounds or their mixtures of synthetic materials of profiled ribbons for tire treads or sidewalls of automobile tires.
    The purpose of the invention is to improve the quality of products and reduce material loss when changing the mixture.
    Fig. 1 shows a head of a multi-punch profile press with extruders related thereto, a longitudinal section; in fig. 2 - control unit, longitudinal section.
    The installation, which explains the proposed method, consists of the head of a multi-lancet profile press 1 with the upper part 2 withdrawn upwards, the non-native 5-sided middle part 3 and the folding lower part 4. In the head | tapering intrusion channels 5, 6 and 7 are made, which are included in the preliminary pattern 8 and then into: a plate mold 9.
    Extruders 10, 11, and 12 are connected to intrusion channels 5, 6, and 7 with drive motors 13, 14, and 15 extruders 10–12.
    FIG. 2 shows the standard control device 1b., Which p. By means of corresponding pipelines, it is connected to a pressure sensor 17 installed at the entrance to the intrusion channel 7, with a pressure sensor 18 installed installed at the entrance to the intrusion channel 6, and with a pressure sensor 19 installed at the entrance to the intrusion channel 5 "
    Pressure sensors 17j 18 and 19 can also be installed at the outlets of individual extruders near the corresponding lean end of the screw.
    In addition, the control device is connected with three drive motors of 13-15 extruders 10-12. A conveyor belt 20 is intended for receiving the product.
    The proposed method is carried out as follows:
    The drive 1, engines 13-15 of the mouth ™ are turned on simultaneously. Then, the actual pressure at the entrance to the intrusion channels 5-7 1 shi at the output of each extruder is controlled with the help of pressure sensors 17-19 and compared with predetermined pressure gaps using control device 16. If preset
    862
    the pressure value is recorded, for example, by the pressure sensor 19, the control device 16 switches off the drive motor 13 of the extruder 10.
    After reaching the next predetermined pressure, recorded, for example, by means of the pressure sensor 18, the drive motor 14 of the booster 11 is turned off. If the signal from the pressure sensor 17 also reaches a predetermined pressure, the control device 16 will turn off the drive motor 15, immediately after that include all drive motors 13, 14 and 15 at the same time.
    Then, all extruders 10, 11, and 12 evenly feed the material into adjoining intrusion channels 5j 6 and 7, and the volume of material received by the intrusion channels 5-7 is consistent with the feed of individual extruders 10-12.
    Then from the lamellar casting
    Form 9, a full profile arrow 21 appears, consisting of three different rubber compounds, and is fed to a belt conveyor 20. After extrusion of about 1 m of the profile length, a benign profiled strand appears from the head, so that there will be only minor material losses in the head .
    Thus, by scaling the pressure of the material at the outlet of each extruder 10-12 or at the inlet of the head of a multi-punch profile press and shutting off the drive engine when the extruder is connected to the extruder, the corresponding extruder cylinder 10-12 and the channels in the head are completely filled material
    When all extruders are turned on again, the material from all extruder cylinders is simultaneously fed into the channels of the pre-template 8, so that then at the same time and almost in full, it can exit the plate-shaped injection mold 9, i.e. This method of putting the press into operation can be characterized by a minimal loss of a multi-section extruded profile due to an increase in its quality.
    The proposed method provides only the minimum amount of waste material after each process of putting the press into operation, which is important,
    since during the work shift, for example, from eight to ten times, it is necessary to change the mixture.
