Abstract
An apparatus for automatically severing a slide fastener chain having a succession of fabric pieces attached to each of the opposed longitudinal marginal edges with a gap portion interposed between each adjacent pair of fabric pieces comprises a feeding unit; a cutting unit disposed on a feed path for severing the fabric-pieced slide fastener chain transversely across the gap portions; and detecting means for producing a signal only when laterally-aligned gap portions reach the detecting means. The detecting means, feeding unit and the cutting unit are electrically connected such that, upon receipt of the signal from the detecting means, the feeding unit is deenergized and at the same time the cutting unit is energized.
