ABSTRACT:
A strap for the production of load lifting slings equipped with lifting loops and tie loops arranged parallel thereto is composed of a webbing fabric. In a width region arranged at a distance from both side edges of the strap, in which a cut is to be made in the longitudinal direction of the webbing through the transverse bond, the warp yarns of the webbing fabric are formed of textile yarns (meltable yarns) of a synthetic material whose melting temperature is lower than the melting temperature of the warp yarns in at least the width region of the strap forming the lifting loop. The cut to produce the tie loop is made by a hot cut under the influence of heat in such a manner that only the meltable yarns melt.
