ABSTRACT:
A process and associated apparatus for joining automatically the beginning and the end of a hem in a circular textile material is disclosed. The material is fed on to an entry roller which receives the cloth from a flat guide, the said roller being inclined at the moment of the initial introduction of the material followed by the material being fed and guided with the principal roller being horizontal, this being followed by the pre-folding and final folding of the edge of the material by fold guides prior to the stitching of the hem until the already sewn section of the hem reaches the entry of the guide unit, at which moment the said unit is displaced for the realignment of the hem stitching zone, following which the fold guides are separated.
