ABSTRACT:
A method and apparatus for sewing cover halves together around a baseball core or the like. The method includes the steps of advancing first and second needles in one direction over an edge of a first cover half and under and through an edge of an adjacent second cover half. The needles carry first and second double threads through the second cover half. The ball cover is then indexed forward and the first and second needles are advanced in an opposite direction over the edge of the second cover half and under and through the edge of the first cover half for carrying the first and second threads over the edge of the second cover half and through the edge of the first. Prior to the second step of advancing, the second thread is positioned between the first and second needles and above the first needle so that a regular herringbone stitch pattern between the first and second cover halves is achieved as the steps are sequentially repeated. The apparatus includes first and second needles and means for shuttling the needles in parallel, and abreast, back and forth over and under and through opposing cover halves. During every other shuttle motion a tab holds the second thread between the needles and raised the thread above the first needle so as to create a regular herringbone stitch pattern between the first and second cover halves.
