Embodiment

[0053] Using the rubber belt manufacturing apparatus of the above-mentioned embodiment, rubber belts can be manufactured from rubbers with different compoundings A to F shown in Table 1, and the degree of adhesion of the rubber to the calender rolls was tested.

[0054] [Table 1]

[0055] (unit weight%)

[0056]

[0057] "E" in the "Compounding method" column of Table 1 indicates rubber compounded from latex (emulsion superposition method). Also, "S" represents a rubber compounded from a solution (solution compounding method). Likewise, "E / S" indicates a mixture of latex-compounded rubber and solution-compounded rubber.

[0058] Table 2 shows the temperature of the calender rolls and the sticking degree of the rubber. Evaluation for the next four grades.

[0059] A: The rubber tape is not attached to the roller main body.

[0060] B: Although the rubber tape is attached to the roller main body, it does not affect the cross-sectional shape of t...

Abstract

A method for producing a rubber strip (Gs) using a rolling means (4) for rolling rubber (G) continuously discharged from a discharging port of a rubber extruding means, to form a narrow rubber strip (Gs), wherein the method comprises a step for heating the rolling means (4), a step for measuring the temperature of the outer peripheral surface of the rolling means (4), and a temperature control step for comparing the measured temperature (Tk) and a set temperature (Ts) set in advance on the basis of at least one item of information from among the type, temperature, shape, and rolling speed of the rubber (G), and, when the measured temperature (Tk) is low, heating the rolling means (4) to keep the temperature of the rolling means (4) at the set temperature (Ts).

Description

technical field [0001] The present invention relates to a manufacturing method and a manufacturing apparatus capable of manufacturing a high-quality rubber belt by suppressing rubber sticking to a calendering mechanism for rolling rubber to form a rubber belt. Background technique [0002] In recent years, in order to improve the productivity of tires, for example, various tape-winding methods have been proposed in which narrow-width belt-shaped rubber belts are overlapped and wound in a helical shape to form tread rubber. Figure 7 An example of the apparatus a for manufacturing the above-mentioned rubber belt is shown. The apparatus a includes, for example: a rubber extruder a that continuously discharges rubber from the discharge port b; upper and lower calender rolls c, c that roll the rubber from the discharge port b to form a belt-shaped rubber belt e; The rubber belt of c is pulled by the pulling roller d. The continuously produced rubber belt e is conveyed downstrea...
