Abstract
A method of forming successive space portion in a slide fastener chain, comprising: positioning the chain in such a manner that an element contiguous to the backward end of a prospective space portion is brought into engagement with a positioning pin upstream of a cutting unit; positioning the chain in such a manner that an element contiguous to the forward end of the prospective space portion is out of engagement with another positioning pin downstream of the cutting unit, and then positioning the chain, as the feed roller is rotated forwardly to extend the chain so that the positioning pin is inserted between the elements, whereupon the downstream positioning pin is brought into engagement with the element adjacent to the prospective space portion as the feed roller is rotated backwardly to restore the slide fastener chain; and cutting off elements of the prospective space portion and removing the cut elements from the prospective space portion.
