Abstract
A method of attaching top and bottom stops to a slide fastener chain at one and the same stage of manufacture. The fastener chain is moved along a path until a trailing end of a preceding pair of coupling element groups arrives at a first fixed die, by which time leading end portions of a succeeding pair of coupling element groups are disengaged from each other. With the trailing end of the preceding pair of coupling element groups retained at the first die, an adjacent pair of opposed blank tape portions is sagged until the endmost disengaged coupling elements arrive at a second fixed die spaced a predetermined distance from the first die along the path. Finally, a bottom stop and a pair of top stops are attached concurrently and respectively to the trailing end of the preceding pair of coupling element groups at the first die and to the disengaged endmost portions of the succeeding pair of coupling element groups at the second die. An apparatus for carrying out this method is also disclosed.
