Description of the Related Art Conventionally, a so-called doubling system or a multi-layer extrusion system has been known as a method for laminating different kinds of unvulcanized rubber on unvulcanized rubber extruded from an extruder in a tire manufacturing process. In the former doubling method, for example, unvulcanized rubber extruded in a strip shape by an extruder or thinner unvulcanized rubber is pre-wound on a winding machine, while a different type of unvulcanized rubber is fed from a separate extruder. The vulcanized rubber is extruded and conveyed on a conveyor. In the middle of the conveyance, unvulcanized rubber is unwound from the winder and is adhered to, for example, the back surface of the unvulcanized rubber on the conveyor. In the latter multi-layer extrusion method, for example, two upper and lower screws are built into the extruder, and different kinds of rubber or rubber-like materials flowing in independent rubber passages through the respective screws are merged in the head, and a rubber discharge port is provided. It is one in which a plurality of layers are continuously extruded.

得ない欠点があった。However, the former doubling method requires a step of winding one unvulcanized rubber on a winding machine, and further, the winding machine is not vulcanized on the other side. Work to move the rubber directly under the rubber conveyor, guide the unvulcanized rubber unwound from the winder to the sticking surface of the unvulcanized rubber on the conveyor, and position it with the help of an operator. Was needed. Therefore, there is a problem that the work efficiency is lowered. On the other hand, in the latter multi-layer extrusion method, there is no reduction in work efficiency, but since multiple screws are built into the extruder, this leads to an increase in equipment size, lacks flexibility, and unvulcanization to be laminated. If there were changes in various sizes of rubber, there was a drawback that could not be easily dealt with.

During the transportation of the unvulcanized rubber, the upper or lower surface of the first unvulcanized rubber and the rubber discharge port of the second extruder during the transportation are brought close to each other until reaching a suitable gap position. In this state, the second unextruded rubber is extruded in a strip shape from the rubber discharge port of the second extruder on the laminated surface of the first unvulcanized rubber.
By directly attaching the unvulcanized rubber of No. 2, it is unnecessary to guide and align the tip of the second unvulcanized rubber.

When the unvulcanized rubber is laminated, when the unvulcanized rubber is laminated, the method of the present invention described above is suitably realized by bringing the unvulcanized rubber close to a position suitable for attaching the vulcanized rubber. On the other hand, if you retreat that part,
The second unvulcanized rubber does not need to be attached and only the first unvulcanized rubber can be extruded. Therefore, the above two cases can be arbitrarily selected by the space adjusting mechanism of the laminating apparatus.
