replacing pull tabs, this procedure is reversed. Pull
tabs furnished as replacements need only to be
squeezed onto the slider.
To repair a damaged slider, you must first
remove it. The proper procedure for removing and
replacing a slider on the chain following repairs
is explained in the following paragraphs.
To remove the slider from the regular type
interlocking slide fastener (nonseparating),
carefully rip the stitches from the BOTTOM of
the interlocking slide fastener to expose the ends
of the tape. Then remove the bottom stop, and
slip the slider off the bottom of the chain and
entirely off the beads and tape, as shown in figure
To replace the slider on a regular type
interlocking slide fastener, thread the two bottom
beads into the wide end of the slider. Hold the
tape so that the bottom teeth are correctly
matched; then draw the slider upward until the
teeth mesh for several inches. Without allowing
the teeth to separate, clamp the bottom stop close
to the teeth and over both beads. Replace the tape
ends and ripped stitches by hand or by machine.
To remove a damaged slider on a separating
type slide fastener, carefully rip the stitches at the
TOP of the slide fastener, on the retainer side
only, thus exposing the end of the tape. Remove
the top stop, slip the slider off the top of the chain,
and completely remove it from the bead and tape.
Repair or replace the slider.
To replace the slider on a separating type
interlocking slide fastener, thread the bead on the
retainer side into the narrow end of the slider, and
allow the slider to slip down the chain. Replace
the tape end and ripped stitches by hand or
To replace the slider on the top of a regular,
nonseparating type interlocking slide fastener with
the aid of pull-up pliers, slip the tool over the
bottom stop, clamp together, and pull upward.
Close the entire chain in this manner. Thread the
two top beads into the narrow end of the slider,
holding the teeth meshed until they enter the
slider. Replace the top stops, tape ends, and
Shortening an Interlocking Slide Fastener
To shorten an interlocking slide fastener, first
determine the length required. The chain should
be about one-half inch shorter than the opening
in the material or garment. Mark the desired
length, measuring from the bottom stop upward.
Open the chain to any point below this mark and
cut directly across the tape about 1 inch above
the mark. Cut the excess teeth from the marking
point to the end of the tape, and replace the two
stops, crimping them firmly.
Installing an Interlocking Slide Fastener
The installation of an interlocking slide
fastener varies with the type of job. Some are
curved, some have rounded comers, and some are
hidden. The installation of a straight slide fastener
is described in the following paragraphs.
Slide Fastener Presser Foot
To install a slide fastener neatly and easily,
you should use a slide fastener presser foot on the
sewing machine. The slide fastener presser foot
serves not only as a guide for a neat row of
stitches, but also prevents the foot from riding
up on the chain.
The sewing machine manufacturer can supply
a regular slide fastener presser foot (right or left)
for any sewing machine, or one can be made
locally. File or grind the left side of an old presser
foot to permit sewing to within 1/8 inch of the
When sewing, always stretch the slide fastener
and not the material, as this makes a flatter and
