Storage device for bead of tire [0001]

The present invention relates to a storage device for a bead for a tire, and more particularly to a storage device for a tire bead capable of storing a plurality of tire beads without sticking to each other without a separate separator.

Generally, a heavy-duty pneumatic tire has a tread in direct contact with the road surface during running, a carcass layer wrapped around the tread and turning up both bead bundles, and a carcass layer positioned between the tread and the carcass layer, A belt layer, an inner liner inserted into the carcass layer to prevent air leakage inside the tire, a side wall serving as a side surface of the tire, a shoulder positioned between the tread and the side wall, And beads to be mounted.

The tread is a thick rubber layer in contact with the road surface. The tread is resistant to rolling and impact in order to protect the carcass layer and the belt layer in the tire, and is made of rubber having high abrasion resistance in order to increase the running life of the tire. The shoulder is made of a structure that can easily dissipate the heat generated inside the tire, and the sidewall protects the carcass layer and flexibly flexes to improve ride comfort. The carcass layer is an important part of the skeleton of a tire. It refers to the entire layer of the tire cord fabric, and is resistant to air pressure, load, and impact inside the tire. The belt layer is a layer interposed between the tread and the carcass layer. It mitigates the impact from the outside when traveling, prevents the tread from cracking or trauma to reach the carcass layer directly, widens the area of the tread touching the road surface, It plays a role of improving stability. The inner liner is a rubber layer disposed inside the carcass layer and serves to prevent air leakage.

Among the semi-finished products constituting the tire, the bead is a part for bonding the tire to the rim of the vehicle. The bead is wound by several layers of steel with various thicknesses of steel and is wound in several layers and completed by attaching extruded rubber called Apex.

Typically, at the tire manufacturing site, the finished bead is carried to the molding machine by hanging several pieces together on a frame made by welding a support rod to a general frame. When the plurality of beads are put on the hangers, a separator made of plastic is interposed between the beads so as to prevent the adjacent beads from sticking to each other.
