Embodiment Construction

[0024] Next, a method for producing a laminate according to a specific embodiment of the present invention will be described with reference to the drawings.

[0025] In this specific embodiment, the case where the laminate is a tape core, the case where the laminate is a semi-finished product such as an intermediate laminate described below, and the case where the laminate is a final product, namely a conveyor belt, will be described.

[0026] First, the structure of the conveyor belt will be described.

[0027] figure 1 It is a cross-sectional view of the conveyor belt 10 after it is broken on a plane parallel to its width direction. (A) shows the state before cutting the end portions B on both sides, and (B) shows the state after cutting the end portions B on both sides.

[0028] The transmission belt 10 structurally includes a belt core 12 , a first covering rubber 14A, a second covering rubber 14B, and ear gels 16 .

[0029] The belt core 12 is formed by laminating a plu...

Abstract

In the present invention, when, while forming a first sheet-shaped member (S1) by rolling a rubber material extruded from a first rubber extruder (32) between a first pair of rollers (36, 36), continuously producing a laminate resulting from laminating the first sheet-shaped member (S1) and a second sheet-shaped member (S2) by overlapping the first sheet-shaped member (S1) and the second sheet-shaped member (S2) supplied from an original material and rolling between a second pair of rollers (38, 38), the gap between the first pair of rollers (36, 36) is controlled on the basis of the detection results of the thickness (d1) of the first sheet-shaped member (S1) rolled by the first pair of rollers (36, 36), the detection results of the thickness (d2) of the second sheet-shaped member (S2) supplied from the original material, and the detection results of the thickness (d3) of the laminate body.

Description

technical field [0001] The present invention relates to a method for producing a laminate. Background technique [0002] As a transmission belt, there is known a belt core, a surface covering rubber and a back covering rubber laminated on the surface and back of the belt core, and ear glues arranged on both sides in the width direction of the belt core between these covering rubbers. conveyor belt. [0003] Conventionally, as a production method of such a conveyor belt, a production method including the following steps is known: (1) a step of mixing rubber materials, (2) a step of rolling and molding a belt core, (3) a step of applying The process of calendering and molding, (4) the process of molding the ear gel, (5) the process of gathering and molding the materials provided in these separate and independent processes (2), (3), and (4) into a conveyor belt , (6) the process of vulcanizing the formed conveyor belt, and (7) the process of surface processing the vulcanized ...
