Abstract

According to the fastener chain, method and apparatus for forming ends thereof, coil-shaped fastener elements as linear fastener elements are attached and sewed to side edge portions of a pair of fastener tapes with sewing yarns as fixing yarns while a core thread is inserted through the fastener elements. The coil-shaped fastener elements are cut off at leg portions, each of which is in contact with the fastener tape, at ends of the fastener elements, so that cut end portions are formed. These cut end portions are pushed inward of the side edge portions, and then, the leg portions and inverted portions thereof are fused to the fastener tapes by heating. As a result, a form of each end of the fastener elements is stabilized, so that the resultant slide fastener is good in safety.
