As shown in the figure (see Figure 5 of the above-mentioned publication), a main drum 3 and a sub-drum 5 are arranged with their axes parallel to each other and separated from each other, and one of these drums is connected to the other. It has a liner 4 made of a flexible material that can be wound up, and is rolled up on the main drum 3 at the same time as a liner 4 made of cloth, for example, while extruding the tread band 1 from the extruder and interposed between each winding of the liner 4. . At this time, as shown in FIG. 6 (see FIG. 6 of the above-mentioned publication), the lower surface of the tread band 1 adheres to the surface formed by the liner 4 over its entire surface, and each spiral of the liner 4 is supported on the protrusion 1d of the lower rubber spiral. The step band 1 is stored in this state until it is needed for use. Therefore, if the length of the tread band 1 is, for example, 75 m, and the diameter of the main drum after winding with a cloth liner is approximately 80 cm, the protrusions 1d overlap in a spiral manner. It is pressed due to the weight of step band 1 and is approximately 0.6
There is a problem that mm is also crushed and deformed. Therefore, the uniformity performance of a tire product manufactured using the tread band 1 in which the protruding portion 1d is deformed is approximately
There is a problem that 2.4Kg, that is, 0.4Kg per 0.1mm of deformation, is significantly worse. Even when a deformable sponge liner is used in place of the cloth liner according to the shape of the tread band, the protrusion 1d is approximately
A deformation of 0.3mm occurs, greatly deteriorating the uniformity performance.

(Operation) Next, the operation will be explained. In the dual-type rubber-like long material storage device 10, the first take-up reel 1
5 and the second take-up reel 15' operate simultaneously and synchronously.

First, the following preparations are made before winding work. The rubber-like long material storage device 10 is placed at a predetermined position near the extruder, and the rubber-like long material storage device 10 is installed by inserting the tip 41b of the bar 41a of the stopper 41 into the fixing hole 42 in the floor surface. Ten positions are defined. At the first clutch 23 and the second clutch 23' on the first rotating shaft 12, two sleeves 25, 2
5' is engaged with the sleeves 24, 24' using levers 25a, 25a', respectively. The two reel stop levers 27a, 27a' are inserted into the reel fixing holes 14c, 14c', respectively, and the rotation of the take-up reel is fixed. The first rotating shaft 12 is connected to the drive device A, and the brake 3 of the second rotating shaft 17a
7 is in a state where the brake is on. The third clutch 32 and the fourth clutch 3 on the second rotating shaft 17a
2' are sleeves 35, 35' and sleeve 3, respectively.
3 and 33' are engaged with each other, and a predetermined braking force is applied to the two liner drums 17 and 17'. The tip end 16a of the long liner 16 wound around the liner drum 17 is pulled out from the liner drum 17 by a predetermined length, and the guide plate 18
It is guided in an arcuate manner. On this occasion,
The width of the liner 16 is narrower to the width M of the lower end portion 18b of the guide plate 18, which is narrower than the distance L between the inner surfaces of the side wall members 14, and the tip portion 16a is narrower than the distance L between the inner surfaces of the side wall members 14.
As the liner 16 passes between the inner surfaces of the guide plate 18 and moves downwardly away from the lower end 18b of the guide plate 18, the liner 16 gradually changes from an arc shape to a flat plate shape due to the restoring force of the liner 16 itself.
The tip portion 16a is connected to the spiral engaging portion 13 of the side wall member 14.
The fixing tool 15c at the center of the take-up reel 15 engages with the engagement slit 13a between the

The driving force is transmitted to the first rotating shaft 12 and further to the take-up reel via the first clutch 23 and the second clutch 23', and the first take-up reel 15 and the second take-up reel 15' are moved at the same predetermined speed. Start rotating. Since the tip end 16a of the liner 16 is fixed to the fixture 15c of the take-up reel 15, the liner 16 is wound around the engagement slit 13a of the take-up reel 15 as the take-up reel 15 rotates. During this time, the side tread rubber 20 discharged from the extruder is moved from the upper right to the lower left in the figure after a predetermined process, as shown in FIG.
The take-up reel 15 is circumscribed on the outer surface of the side tread rubber 20 along with the liner 16c unwound from the liner drum 17 on the outside of the side tread rubber 20.
It is wound up.

As shown in FIG. 4, the engaging portion 13 is formed with an engaging slit 13a having a spiral of a predetermined pitch, so that the protruding portion 20a of the side tread rubber 20 and the liner 16 are spaced apart from each other by a predetermined distance. Therefore, the protrusion 20a does not deform at all. Furthermore, since the liner 16 has a predetermined rigidity, even if the liners 16 overlap in a spiral shape, the weight of the side tread rubber 20 is supported by the engaging portion 13.
Liner 1 due to the weight of side tread rubber 20
6 will not be deformed beyond a predetermined value. After a predetermined length of the side tread rubber 20 is wound onto the take-up reel 15 in this manner, the first rotating shaft 12 is disconnected from the drive device A. The reel stop levers 27a, 27'a are inserted into the fixing holes 14c, 14'c and fixed, and the winding operation is completed.

Next, the bar 41a for fixing the cart is removed from the floor fixing hole 42, and the cart 11 is moved to a predetermined location by a transport device (not shown). After the predetermined storage period has elapsed, the cart 11 is again moved to a predetermined location for the next process by a transport device (not shown).
