Abstract
Abstract Overlapped fabric end portions define a fabric double layer. A plurality of loops are formed in the double layer extending alternately in opposite directions transversely of the double layer to define a transverse row of loops. Elongated substantially rigid rod means extends through the row of loops for splicing the fabric end portions together.
