Description

  The present invention relates to a method and apparatus for peeling a belt-shaped member from a liner, and more particularly, from a high-rigid belt-shaped liner without pulling and deforming a belt-shaped rubber-like elastic member wound around the high-rigid belt-shaped liner. The present invention relates to a stripping method from a liner of a belt-shaped member that can be reliably separated and transported to the next process, and an apparatus therefor.

  Conventionally, in a tire molding process or the like, as a method of storing unvulcanized rubber-like elastic members such as tire treads and side rubbers that have been molded and extruded from an extrusion device until the time of tire molding, a band-like rubber-like elastic member that has been cut into a fixed length is used. Is stored in multiple stages on a cart called a kerry truck, and in recent years, unvulcanized rubber-like elastic members that have been molded and extruded are rolled with a take-up liner without being cut into a regular length. A method of winding in a shape, unwinding immediately before use during molding, and cutting it to a standard length is used (for example, see Patent Document 1 and Patent Document 2).

  The method of winding in the form of a roll with the winding liner as described above is superior in terms of suppressing the shrinkage of the shape and size of the material and ensuring the dimensional accuracy as compared with the method of cutting and storing in a fixed size.

  By the way, as a material used in the conventional winding strip liner, a cloth strip liner or a rigid polyethylene strip liner is mainly used, and in such a strip liner, the wound unvulcanized strip rubber elastic When unwinding the member, as shown in FIG. 10, it is necessary to change the band-like rubber-like elastic member W from the belt-like liner R in a small curvature with a small curvature between the small-diameter rollers Sa and Sb. there were.

On the other hand, when separating a band-like rubber-like elastic member from a high-rigidity belt-like liner made of steel, aluminum, etc., the high-rigidity belt-like liner has rigidity, so the high-rigidity belt-like liner has a small curvature as described above. Therefore, there has been a demand for a method for efficiently separating and unwinding the belt-like rubber-like elastic member without causing tensile deformation or the like.
