Abstract

PURPOSE:To cut the belt like material having stickiness without deforming the shape of its cutting section, by cutting the material to be cut with a cutting blade, then parting the cutting blade and the cut material and returning the cutting blade to its original position. CONSTITUTION:After the belt like material 3 of an unvulcanized tire constituting material, etc. which has stickiness and is to be cut is cut with a cutting blade K, the cutting blade K and the cut material 3 are parted, then the cutting blade K is returned to its original position. By this, the relatively narrow and thick belt material which is to be cut and has stickiness like e.g., an unvulcanized sidewall or a filler can be cut surely into a desired shape without deforming the shape of its cutting section. Therefore, the cutting process of the belt like material 3 which has been hitherto a bottleneck in a production line can be automatized and the productivity and the quality of a product can be improved.

This is because the unvulcanized sidewalls, fillers, etc. that make up the tire are sticky, so the material to be cut and the cutting blade come into close contact or stick to each other during cutting, resulting in deformation of the shape of the cut surface. This is because there is a problem. This tendency becomes particularly noticeable when the material to be cut is cut diagonally in relation to the next process.

As explained above, after cutting the material to be cut, the cutting blade and the material to be cut are separated and then the cutting blade is released, which completely solves the conventional problem of the cutting blade and the material coming into close contact during cutting. In the green tire forming process, sticky, relatively narrow and relatively thick tire constituent materials such as sidewalls and fillers are automatically supplied to the tire forming drum and wrapped. It can be cut, cut, and joined.

In particular, the method of the present invention can reliably perform diagonal cutting of the material to be cut, so it is possible to reduce the difference in level and thickening of the material at the joint between both ends of the material, and therefore it is possible to improve productivity as well as to facilitate automation. This makes it possible to eliminate manual work, improve joining accuracy, and improve tire quality.

As described above, in the present invention, after the material to be cut is cut by the cutting blade, the cutting blade and the material to be cut are separated, and then the cutting blade is returned to its old position. Adhesive, relatively narrow and thick strip materials such as sulfur sidewalls and fillers,
By changing the shape of the cut surface, it is possible to reliably cut the material into a desired shape.
