Title:
タイヤを製造するための方法および装置
Document Type and Number:
Japanese Patent JP2008500915
Kind Code:
A
Abstract:
A robotized arm drives in rotation a drum carrying a tire being processed and conveniently moves it in front of a delivery nozzle supplying a continuous elongated element of elastomer material in order to form a tire component. The delivery nozzle is connected through at least one selecting valve with two or more extruders, each designed to supply a respective blend. The selecting valve connects the delivery nozzle with the outlet of one of the extruders, breaking communication between the nozzle and the other extruders. The outlets of the non-active extruders can be connected with at least one outlet duct. It is thus possible to replace the type of blend used for manufacturing the tire component without the article of manufacture having to be moved away from the delivery nozzle.
