A cord drying apparatus dries cords for forming cord-inserted bands, such as belts and components of tires, such as carcasses. A plurality of cords C unwound from a plurality of reels 1a held in a wheeled creel 1 are passed through guide holes formed in a guide plate 21 and are extended to an insulation head 6. Vertically movable rollers 4 are moved down from their home positions above the cords C to cause the cords C to extend along curved heating surfaces of heating boards 5. The cords C are moved along the heating surfaces of the heating boards 5 to dry the cords C. The cords C can be easily extended along and pressed against the heating surfaces of the heating boards 5. Thus cords C can be changed in a short time and the efficiency of operations for drying cords C by a drying process can be improved.
A cord drying method used in a process of processing cords for forming a component member of a tire by passing cords pulled out from a wheeled creel through a guide plate to extend the cords parallel to each other, delivering the parallel cords to an insulation head, and processing the parallel cords by a covering process by the insulation head to coat the parallel cords with rubber, said cord drying method comprising the steps of:
