摘要
An apparatus for feeding elastomeric strips used to form an annular tread reinforcing structure of a vehicle pneumatic tire provided with reinforcing metal cords to a drum which forms the strips into the annular reinforcing structure is disclosed. The apparatus comprises an endless belt looped about spaced pulleys which transfers cut lengths of an elastomeric strip for making an annular tread reinforcing structure from bobbins of the strip to a drum which shapes an annular tread reinforcing member therefrom. The cut lengths of elastomeric strip are maintained in the desired position on the belt and drum by the action of two separate magnetic fields. One of the magnets is stationary and is placed under the belt. The other magnet is adjacent to the belt pulley nearest the drum. Apparatus is provided for laying automatically the two ends of the elastomeric strip on the belt.
