Abstract (en)
A continuous length of sheet material is fed until its leading edge is detected and is then stopped and clamped. After than an intermediately positioned tensioning and folding means draws out under tension further material from the stop feed mechanism. This sets up the material for transverse clamping and severing of the already folded lengths. The transverse severing is preferably effected by deflecting the material into the path of a band knife parallel to the material face. The severed and folded unit length can be further progressed, either folded or partly completed unfolded e.g. to a cut-and-lay stack or to suitable sewing heads.
