Abstract
The invention resides in enabling high-mix low-volume production by a compact apparatus for a rubber sheet reinforced with a cord of a belt material for a tire, a body-ply material, etc. variously changing a cord material, cord arrangement angle, width of sheet, etc. and relates to manufacturing apparatus and method for a rubber sheet reinforced with a cord according to wrapping around a rubber coated cord group continuously on a surface of a pair of a cylindrical rotating body rotating in the same direction or on a surface of a cylindrical rotating body disposed small diameter roller groups of plural number on a side surface of a cylinder.
Claims32
A manufacturing apparatus for a rubber sheet reinforced with a cord comprising:
- a pair of cylindrical rotating bodies rotating in the same direction is disposed an axial direction of a cylinder obliquely from parallel only predefined angle,
- a supply guide supplying a rubber coated cord group to the cylindrical rotating body,
- a cylindrical rubber sheet formed by spirally wrapping continuously contacting with each other the rubber coated cord on a surface of the pair of cylindrical rotating bodies by a rotation of the pair of cylindrical rotating bodies,
- and the cylindrical rubber sheet is formed to send on the pair of cylindrical rotating bodies to an axial direction of a cylinder.
A manufacturing apparatus for a rubber sheet reinforced with a cord comprising:
- small diameter roller groups of plural number disposed on a side surface of a cylinder,
- each axis direction of small rollers of the plural number formed of a cylindrical rotating body disposing obliquely a predefined angle from parallel with an axis direction of a nearby small roller,
- a supply guide supplying a rubber coated cord to the cylindrical rotating body,
- a cylindrical rubber sheet formed by continuously spirally wrapping the rubber coated cord group to contact with each other on a surface of the cylindrical rotating body by a rotation of the cylindrical rotating body,
- and the cylindrical rubber sheet is formed to sent on the cylindrical rotating body to an axial direction of a cylinder.
