Abstract
Abstract This invention relates to an apparatus for applying mainly a thin rubber sheet, such as an inner liner or insulation, onto a tire making drum, which is used in a series of raw tire making processes. The apparatus can realize a proper applying of the sheet in such a manner that the rubber sheet, not previously cut to a specified length although it is longer than the circumference of the drum, is pressed at the foremost end onto the tire making drum, is applied thereto in a length corresponding to about one circumference of the drum through rotary control thereof, is thereafter cut automatically to the specified length, and is subsequently applied at the rear end of the cut sheet onto the drum.
