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.
Claims2
An apparatus for applying a rubber sheet onto a tire making drum comprising:
- a movable main frame,
- a tire making drum for applying thereto a rubber sheet, provided rotatably in the vicinity of one end of the movable main frame,
- a sheet attracting and transferring means, located adjacent to the movable main frame, for attracting a long rubber sheet in the vicinity of its initial end and for transferring the long rubber sheet to the tire making drum,
- a press roller means, disposed adjacent to the tire making drum, for press-contacting the initial end of the long rubber sheet onto the tire making drum, and
- a cutter means for subsequently cutting the long rubber sheet, already applied onto said tire making drum, to a length corresponding to about one circumference of the tire making drum, said cutter means being provided adjacent to the sheet attracting and transferring means.
