    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.

    The invention relates to chemical engineering, in particular to folding multi-position extrusion heads, containing nozzles and used in the manufacture of tires.
    The purpose of the invention is to simplify the process of changing nozzles,
    FIG. Figure 1 schematically shows a folding multi-extrusion head, connected by means of feed channels to four extruders (the upper and lower parts are depicted in a folded-down state), a longitudinal section; in fig. 2 shows an embodiment of the nozzle, profiled on both sides and moved by means of a hydraulically pushing rod configured with controllability; FIG. 3 shows a nozzle with a pushing pin, placed in the form of a toothed rack.
    The hinged multi-position extrusion head includes a housing 1 with full supply channels 2 therein, respectively, for a tread compound, a mixture for the upper arm, a rubber compound for the durable portion, and a rubber mixture for dl. for example, with four extruders 3. In an embodiment, the extrusion head can be communicated with other sources of the feed mixture via feed channels 2. The extrusion head contains a nozzle with an outlet (not shown), a fixedly mounted middle part 4 and mounted with the possibility of tilting the upper 5 and lower b parts located between these parts with the possibility of replacing the nozzle 7 and 8, respectively. In nozzles 7 and 8, the upper 9 and lower 10 working channels are made. The nozzles 7 and 8 are designed to move them in the supply channels 2 to provide free access to them by means of controllable hydraulic, pneumatically or mechanically pushing rods 11. The extrusion head is equipped with them. The nozzles 7 and 8 in this position are connected to the push rods 11 detachably. The extruders 3 are equipped with feed hoppers 12 for feeding them with various rubber compounds. For tilting the top 5 and bottom 6 parts around the turning points 13 and 14

    respectively, the extrusion head is provided with hydraulic cylinders 15 and 16, respectively. In the embodiment
     The push rods 11 are made up of 7 toothed racks 17 placed in nozzles 7 and associated with a rack and pinion gear 18 for moving them, respectively, either in the direction of direction 10 with the outlet or in the opposite direction. In the wah, the nozzles 7 and 8 are connected to the push rods 11 using bayonet bolts (not yet 5) or locking screws 19. In this case, the nozzles 7 and 8 are fixed on the piston rod 20 of the hydraulic cylinder 21, for example, by locking screws nineteen.
    20 Multiple tilt, extrusion head works as follows,
    Extruders 3 through boot
    25, the funnels 12 are fed with various rubber compounds, i.e., a tread compound, a mixture for a tire shoulder, a rubber mixture for the lower portion, and a rubber mixture for the upper portion. Thus, four rubber compounds differing greatly in their viscosity enter the body 1 of the extrusion head through feed channels 2. Due to the fact that the medium 35 part 4 of the extrusion head is stationary and the top 5 and bottom 6 are installed with the possibility of tilting, the process of changing between 40 parts of the nozzles 7 and 8 with the upper 9 and lower 10 working channels is simplified, for example, tread pattern changes. In addition, the cleaning process of nozzles 7 and 8 is facilitated,
    45 ° if a rubber or elastomer mixture is to be supplied to one or all extruders 3. Further, the removal or cleaning of the screws of the extruders 3 is facilitated.
