Abstract
In a method of manufacturing a rubber coated twisted wire cord, when an outer circumferential surface of a twisted wire cord that is moving from an unreeling unit to a winding unit is coated with unvulcanized rubber extruded by a rubber extruder, by a coating unit disposed between the unreeling unit and a winding unit, in a state of additional tension being imparted on the moving twisted wire cord by a tension imparting unit disposed at a nearby position on an upstream side from the coating unit in a moving direction of the twisted wire cord, the unvulcanized rubber coats the outer circumferential surface of the twisted wire cord in this state to continuously manufacture a rubber coated twisted wire cord.
Claims6
A method of manufacturing a rubber coated twisted wire cord, which continuously manufactures a rubber coated twisted wire cord by winding a twisted wire cord reeled out from an unreeling unit around a winding unit and by coating unvulcanized rubber on an outer circumferential surface of the twisted wire cord that is moving under tension, wherein
- additional tension for the purpose of not causing unraveling is imparted to the twisted wire cord at a position on an upstream side from a position where the unvulcanized rubber coats the twisted wire cord in a moving direction of the twisted wire cord,
- the unvulcanized rubber coats the outer circumferential surface of the twisted wire cord while the additional tension is imparted, and
- winding the twisted wire cord around the winding unit comprises winding the twisted wire cord coated with the unvulcanized rubber around the winding unit.
