ABSTRACT:
In order to be able to distribute the stretching forces more uniformly when stretching the fabric web in respect of width in the conical entry area of the tentering frame, the edge zones (14, 14') of the fabric web (2) are sprayed with a hot medium, for example hot weak lye, more heavily than the central zone (19). The already stabilized edge zones thus transmit the stretching forces into the central zone, thus avoiding different spacings between the warp threads after the stretching operation. Differentiated spraying is achieved by means of spray pipes (13) which are arranged in a particular fashion.
