Abstract
A process and an apparatus for hooking of a band of a flexible material, intended to be subjected to tensile forces, to a fixation piece, for hooking onto the fixation piece of an envelope of which the end portion is divided along a given length, into a plurality of bands of equal width, the process comprising longitudinally folding one extremity of the band upon itself, at least one time, in such a manner as to form at least one hem (14, 15), transversely gathering the hem in accordian fashion in such a manner as to form a flange presenting a fan-shaped configuration, using a fixation piece provided with a groove of a wedge-shape conjugate to the shape of the flange, the groove having a longitudinal extremity opening toward its apex, and arranging the flange within the groove, the band extending through the open extremity of the groove in such a manner as to create a self-locking of the flange when the band is placed in tension.
