    摘要： The invention relates to an apparatus and method for producing an elastomeric extrudate having a constant cross section area. The extrudate is shaped in to a ribbon through a roller die and applied to a tire surface mounted on a rotating spindle. Digital electronic circuitry is employed to provide precise shaft synchronization at a pre-selected rotational velocity ratio between the rotating shafts. The synchronization assures repeatable velocity synchronization between the source of elastomeric material and a take-up device at the axis of rotation of the two components. The elastomeric material is extruded in a manner permitting control over the wrap operation and the amount of elastomeric material employed for a given cycle.

    摘要： An insulator composition of foamed synthetic resin is supplied to an extruder 3, and the synthetic resin is extruded onto a wire 4a continuously supplied to the extruder 3 at a temperature higher than or equal to a foaming temperature, to cover the wire 4a with the insulator composition. Then, the wire 4a covered with the insulator composition is solidified by cooling in a water-cooling trough 6 movable towards and away from the extruder 3 in a direction of supply of the wire 4a. In this operation, an outer diameter D and a capacitance C of the insulator composition are controlled such that when the water-cooling trough 6 reaches its movable limit, either a deviation .DELTA.D of a detection value of the outer diameter D from its target preset value or a deviation .DELTA.C of a detection value of the capacitance C from its target preset value is selected as a deviation (.DELTA.D or .DELTA.C) that may first exceed a tolerance range upon changing an amount of supply of the insulator composition to the extruder 3, and then the amount of supply is controlled so that the other deviation (.DELTA.C or .DELTA.D) is decreased under the condition where the selected deviation (.DELTA.D or .DELTA.C) falls within the tolerance.

    摘要： A conductive element (22) is preheated by a preheat power supply (34) to an initial temperature which is a function of line speed. The preheated conductive element (22) is advanced through an extruder (32) whereat a cellular insulation layer (24) and a solid plastic insulation layer (26) are extruded thereabout to form an insulated conductor (20). The insulated conductor (20) is advanced through an air gap (38) whereat the cellular insulation layer 24 expands about the conductive element (22). The insulated conductor (20) is then quenched at a point to stop the expansion of the cellular insulation layer by passing the insulated conductor into a cooling bath (40).A capacitance monitor (50) measures the coaxial capacitance of the insulated conductor (20) and develops an error signal. Thereafter, a microcomputer (54) facilitates the adjustment of the temperature of conductive element (22) as a function of line speed and the error signal and the adjustment of the point of quenching as a function of the error signal. The adjustment of the temperature and the point of quenching facilitates control of the expansion of the cellular insulation layer (24).
