The double fold binder folds upper and lower tape edge for a perfectly bound edge. The unfolded tape is inserted through the guide rail, folded under on either side and sewn on with a cover- or chainstitch. For the personal look, the tape can also be self-cut.
Tapes of 36 mm width result in a finished binding of approx. 10 mm.
An accessories holder is required to attach the binder.
