ABSTRACT:
This invention relates to a method of fixing an end of a coiled wire on a take up spool and an apparatus therefor.
When the wire is wound on the take up spool, an initiating end of the wire is caught by a catching pawl such as a snagger on a catching plate (snagger plate) which integrally rotates together with the take up spool and thereafter it is wound on the take up spool. Before or immediately before wire winding on the take up spool ends, a wire introduction cover advances to cover the filled take up spool. At that time, a terminating end of the wire on the filled take up spool is so led as to run along the inner surface of the wire introduction cover and come close to the catching plate. Wire drawing lever means on a wire drawing plate draws up the terminating end of the coiled wire to catch it on the catching pawl so that the initiating and terminating ends of the coiled wire intersect on the catching plate. Thereafter, the intersecting portions of the initiating and terminating ends of the wire are fixed to each other.
