<p>An apparatus and method are described for forming and reinforcing a butt splice (21) along the abutting edges (18, 20) of two elastomeric sheets (12, 14) which typically contain a plurality of reinforcing cords (16) extending parallel to one another and to the abutting edges (18, 20) of the sheets. Each butt splice (21) is reinforced with a splice strip (22, 24) which bridges the butt splice. The splice strip (22, 24) is applied to the butt splice (21) using a splice applicating device (60) containing at least one and preferably two applicator heads (66, 68) which move from a splice strip load position P1 to a third position P3 where an applicator head can press the splice strip (22, 24) into contact with the butt splice (21). First, the applicator heads (66, 68) rotate about an axis between the load position P1 and a second position P2 spaced from the butt splice (21). Then, one of the heads (66, 68) reciprocates toward and away from the splice strip application position P3. The splice strip (22, 24) is held on the applicator head (66, 68) by vacuum until the splice strip is pressed against and adhered to the butt splice (21) at which time the vacuum is released and the applicator head (66, 68) is withdrawn.</p> |
