ABSTRACT:
A spool for winding thereon a flexible elongate material includes a pair of diametrically opposite first pins projecting from one end of a hollow cylindrical body of the spool, a pair of diametrically opposite first recesses defined in said one end of the body, a pair of diametrically opposite second recesses defined in the other end of the body in alignment with the respective first pins, and a pair of diametrically opposite second pins projecting from said other end of the body and disposed in alignment with the first recesses. The first pins and recesses are complementary in shape to the second recesses and pins, respectively. With the pins and recesses thus constructed, the spool can be connected with the identical spools at opposite ends. The spools thus connected constitute a multi-spool winding unit which is driven by a single driving unit.
