Abstract (en)
[origin: WO2020177882A1] A holder (19) is used to press the stitching base (15) against the stitch plate (17) during the first forward stroke of the needle (3) before returning at the first reversal point and holds it in place during loop formation between the stitch plate (17) and the eye (3") of the needle (3) so that the stitching base (15) cannot be lifted by the retracting needle (3), thereby preventing the loop.
