Abstract

A method for producing tissue with the aid of a weaving loom comprising a stop bar, at least one shed and a heddle for carrying out the method. The inventive method is characterized in that warp thread guiding a filling yarn cooperates with a longitudinal heddle connected to the filling yarn and is arranged between the filling yarn and the stop bar of the weaving loom. The warp thread passes through the filling yarn and a longitudinal heddle controlled by a Jacquard device which carries out normal yarn up-and-down movement (down-and-up). Two superposed wefts which are arranged below and under the shed are simultaneously inserted therein. In order to produce a visible section of the filling yarn above a tissue layer (pattern) during the descending (ascending) movement of the filling yarn, the longitudinal heddle is displaced in an ascending (descending) position by the Jacquard device in such a way that the longitudinal heddle provided with a corresponding eye whose lower (top) end is in the center of the shed (central position) prevents the warp thread guided by the filling yarn from moving downward (upward) beyond the shed center, and the lower (top) weft is located outside the sh…
