Abstract: In a process for fashioning a portion of a profiled bead (2), which has been extruded onto an object, in particular a pane (1), fastened in a treatment station (E), in which process an initially shapeless accumulation of material (4) is produced in the portion in question, which accumulation of material is given a final shape corresponding to the uniform cross section, of the profiled bead (2) by means of a moving tool (5), any excess material being expelled in order to be removed, the mass of material (4) is produced by the superposition of two portions of the extruded strip, the second portion being deposited after the die (D) has been moved and repositioned. Advantageously, the tool (5) is, according to the invention, automatically aligned on the profiled bead (2), immediately after the accumulated material (4) has been extruded and after the extrusion die (D) has continued its travel, without moving the object, and is brought into contact with this bead.

Abstract: A tire building machine for building a tread strip onto a carcass is provided and includes a carcass support on which the carcass is rotatably mounted, and a tread strip feed device via which a tread strip is fed onto the carcass. The tread strip feed device includes a linear path support assembly on which a tread strip is supported in a substantially linear disposition. The path support assembly extends from one end of the tread strip feed device at which a cutting device may perform a cutting operation to an end adjacent the carcass. The tread strip feed device is raisable to a feed position at which the tread strip extends tangentially relative to the carcass for feeding the tread strip thereonto in a tire building process.

Abstract: An extruder of the Transfermix type comprises a barrel in which a screw rotates for transporting and mixing visco-elastic compounds. The extruder has an inlet, a compression section, a plasticizing section and an exit section. The plasticizing section is of the Transfermix type, in which a helical groove in the screw varies in cross section from full area to zero area, while the cross section of an oppositely handed helical groove in the barrel varies from zero to full area. A return section follows the plasticizing section, and the operative contact-surface of the return section is formed by a sleeve which forms a cylindrical gap between the sleeve and the screw, the sleeve being axially movable to close or open the gap to produce a continuously adjustable throttle.
