Patent ID: 7175726

Claim:
A method of forming a continuous rubber strip, comprising: pressing a forming nozzle of a rubber strip extruding machine against an outer surface of a tire-building drum by moving the rubber strip extruding machine forwardly towards the outer surface of the tire-building drum; outputting the rubber strip with a predetermined sectional shape from an interior of the rubber strip extruding machine through the forming nozzle; bringing a leading end of the rubber strip into tight contact with the outer surface of the tire-building drum; initiating rotation of the tire-building drum when the rubber strip extruding machine is retreated, so that the forming nozzle is brought to a position in which the forming nozzle is spaced away from the tire-building drum by a predetermined distance; continuing rotation of the tire-building drum thereby accomplishing a winding operation in which the rubber strip is wound on the outer surface of the tire-building drum; pressing again the forming nozzle against the outer surface of the tire-building drum by moving again the rubber strip extruding machine forwardly towards the outer surface of the tire-building drum, at completion of the winding operation; stopping rotation of the tire-building drum; and stopping the outputting of the rubber strip thereby allowing the rubber strip to be cut off.
