Belt-shaped rubber (100) is conveyed to a forming drum. Then, the belt-shaped rubber (100) is cut to a predetermined length by a cutter. When the tail end of the belt-shaped rubber (100) which is being conveyed is detected by a sensor, suckers (31) which convey the belt-shaped rubber (100) while sucking the belt-shaped rubber stop temporarily or the moving speed of the suckers (31) decreases.

Accordingly, the amount of shrinkage of the belt-shaped rubber (100) after extrusion is compensated for, and thus the shrinkage of the belt-shaped rubber (100) is suppressed.
In the present invention, a motion member is pushed upwards by an upwards pushing member, and a pressing member is raised. A support block is moved forwards by the upwards pushing member and a driven member. The cam action from this movement causes the pressing member to be positioned above a filler that is on top of a molding drum balloon. Thus, when the upwards pushing member is lowered, the tip of the filler is pressed against the top of the balloon. In such a state, the molding drum is rotated and the filler is molded in an annular shape. Subsequently, the pressing member is moved away from the filler, and the pressing member is arranged at a retreated position to the exterior of the molding drum. The upwards pushing member and the driven member are separated, and in such a state, the molding drum can be independently rotated.

A first shaft is inserted into the die-reception member and a first hole in the head. An installation member is provided to the top of the die-reception member. By screwing a fastening bolt into a bolt hole in the installment member, and fastening a bolt to the top of a cover plate upon the die, the die is pressed against an inner bottom surface of the attachment part of the die-reception member. A second shaft is inserted into the installment member and a second hole in the die-reception member. Cam surfaces of the first shaft and the second shaft are brought into contact with each other. A bolt is fastened, and, as a result of the reaction force thereof, the cam surface of the first shaft and the cam surface of the second shaft press against each other. As a result of the cam action of the cam surfaces, the first shaft is pulled towards the head side, and the die is pressed against a front surface of the head. Accordingly, an effect whereby rubber leakage from the space between the die and the front surface of the head is inhibited is effectively exhibited.
The present invention addresses the problem of providing a reel support device with which reel exchange can be easily performed. When a reel is rolled into a reel base in a first position, the reel is mounted on decking, from a slope, in a prescribed position of a reel mounting surface. When in a state of having been mounted on the decking, the reel is positioned above the floor surface and separated therefrom. In this state, the real is supported by a shaft of the reel base. When the reel base is moved along rails back to a second position, the reel, as a result of this movement, is detached from the reel mounting surface on the decking, and enters a state of having been raised from the floor surface. The reel is supported by the shaft at the centre thereof, and enters a rotatable state. In this state, a filamentous body, such as a wire, on the reel can be withdrawn while rotating the reel. This wire can be used to produce a required product. When withdrawing of the filamentous body is complete, the actions described above can be performed in reverse order to cause the reel to be moved out of the reel base. Accordingly, reel exchange can be easily performed without employing large devices such as cranes.

Provided is an air emission device for growing plants that emits an air flow equally onto a plurality of plants being cultivated in a plant cultivating facility.

An air flow is emitted onto each new leaf growing on the tip of a stem for each plant for which one stem grows by way of the plurality of air emission units. In this way, the transpiration effect from the leaves is promoted by emitting an air flow onto the new leaves growing on the tip of the stem of each plant, and the taking up of water and fertilizer from the roots of the plants is promoted. Thus, the wilting of leaves can be prevented and tipburn due to insufficient calcium can be avoided. Because the air emission unit is disposed near the new leaves of the plants, the volume of air being emitted by the air emission unit can be small, and damage to leaves caused by adjacent leaves contacting each other due to air being blown strongly can be avoided.

A bead insulation rubber composition capable of providing a pneumatic tire excelling in uniformity. The feature thereof is as follows. The composition contains a vulcanizing agent and is vulcanizable. The JIS hardness A thereof at the unvulcanized stage is in the range of 70 to 99 at room temperature while that at the vulcanized stage is in the range of 90 to 99 at room temperature. The Mooney viscosity thereof at the unvulcanized stage is 60 or below at the temperature during the bead wire coating step. At the unvulcanized stage, as the hardness at room temperature is high, any external force applied to bead core in its twisting direction during the production process would have less impact upon the array of bead wire, thereby attaining exertion of the performance to be naturally exerted. Further, by realization of an appropriate hardness after vulcanization, satisfactorily high performance can be exerted in the final application to a pneumatic tire. Still further, by regulation of the Mooney viscosity at the unvulcanized stage to 60 or less, excellence is ensured in the moldability and handleability at the unvulcanized stage.
