– The following might inhibit zipper stretch:
+ When using fusible interlining (a tape that prevents stretch)
+ When the number of sewing times is above average.
+ When trimming a tape edge.
+ When the sewing pitches are too wide.

* The SOFLEX™ zipper is recommended for curved applications.
– Please note that a small diameter curve (under R100mm) might prevent operation of the zipper.
In addition, notch cutting the zipper tape is not advisable.
