Generally, a green tire is manufactured by manufacturing a semifinished rubber sheet in the form of a sheet using an extruder or other tire semi-finished product manufacturing equipment, and assembling various semifinished products on the molding drum according to the structure of the tire. Accordingly, the installation space of the extruder and the semi-finished product manufacturing facility is required, and the equipment for transportation and storage of the produced rubber members are required to be large-sized and labor-intensive. Particularly, in the case of a method of stacking and assembling various semifinished products on a conventional flat drum, a large working space is required for the production of semifinished products required, and a large number of workers are required, resulting in a decrease in productivity.

 Accordingly, there has been proposed a new green tire manufacturing method in which strip-shaped rubber members are continuously laminated on a molding drum having an internal shape of a tire to improve the durability and uniformity of the tire.

As a part of this, in the United States patent, the rubber strip supplied through the injection nozzle is gradually pressurized to the drawing roll to promote the conveyance of the rubber strip, and while the rubber strip is being suppressed by using the drawing roll, And the release roll is released after the rubber strip is cut.

However, in the above-mentioned U.S. patent, it is difficult to stably cut the rubber strip because the rubber strip is cut by the rotational force of the molding drum, and the length of the end of the rubber strip is not constant So that a lot of problems may occur in the subsequent operation of attaching and winding the rubber strip.
