Description

DETAILED DESCRIPTION OF THE INVENTION

TECHNICAL FIELD [0001] The present invention relates to winding a belt-shaped body of a sheet material such as a tire component on a spool, which is conveyed to a tire manufacturing machine for manufacturing a tire. The spool can be mounted on a trolley, which also supports a liner shell for a liner inserted between the material wound around the take-up shell of the material spool.

BACKGROUND OF THE INVENTION Feeding systems for storing and delivering raw materials, such as those disclosed in US Pat. No. 4,951,892, have also been used in tire manufacturing processes. Handling, storing and transporting the tire components by means of a spool mounted on an A-frame carrier has the advantage that it is clearly convenient, but also has the disadvantage that the material is distorted when wound on the spool. . This is especially true for tread winding where the outer shape of the tread is important and can be distorted during the winding-storage process. The belt wound on the spool may also be so distorted that the storage belt does not meet specifications and must be discarded for that,
The number of terminals per inch of wire in the belt may change. Also, as the components are rolled up with a liner inserted between each layer, the "corner-woven" components may be crushed. Peeling from the liner can be difficult, if not impossible. If the calendered material is wound onto a spool, the center of the roll may be distorted and flattened, and may have to be cut from the liner, wasting expensive liner material. As a result, the manufacturing process is delayed. These problems are believed to be due to distortions caused by excessive pressure applied during the winding and storage process. Heretofore, a center drive winder has been used to rotate a shaft connected to a take-up shell of a spool by a motor so as to take up the spool. Winding tension control to utilize and vary the tension applied to the components wound onto the spool is important, as the tension applied during spooling as the size and diameter of the spool increases must be varied. is there.

In the case where a moving belt is used to wind up a component by contacting the surface of a spool, a surface winder may be used. With traditional surface winders,
If there is no adjustable support to lift the spool and remove its weight from the power transmission belt, the spool will be supported by the power transmission belt and the weight of the spool will distort the material. In this case, the entire weight of the spool is carried by the adjusting means,
Not desirable.

According to one aspect of the invention, there is provided an apparatus for winding a strip of sheet material around a rotatable spool of sheet material, wherein the strip of sheet material is hung on a spool and the spool is rotated. Moving the surface winder and the belt means toward the spool in order to press the band of sheet material against the spool in the apparatus having the belt means moving into engagement with the band. And a belt drive means connected to belt means for rotating the spool so as to convey the band to the spool and wind the band around the spool. An apparatus for winding is provided.

According to another aspect of the invention, there is provided a method of winding a sheet material strip on a rotatable spool, comprising: (a) a sheet material strip on a belt on a surface winder on the spool. (B) moving the surface winder and belt toward the spool to press the strip of sheet material against the spool; and (c) winding the strip of sheet material around the spool. A method is provided for winding a strip of sheet material onto a rotatable spool, comprising taking up and driving a belt to rotate the spool.
