<p>To produce ribbons with longitudinal elasticity, the initial wefts (2) are laid through the knitted wales (8) with their change-over points (6) at a gap from the edge of the ribbon (4). The standing threads are under the first wefts, apart from those at the change-over points over the wefts. A second set of wefts is laid with all the standing threads under them. To produce ribbons with longitudinal elasticity, the initial wefts (2) are laid through the knitted wales (8) with their change-over points (6) at a gap from the edge of the ribbon (4). The standing threads are under the first wefts, apart from those at the change-over points over the wefts. A second set of wefts is laid with all the standing threads under them. The ribbon is heated and shrunk, so that the change-over points of the first wefts are pushed down by the second wefts, to be covered by strips of an elastomer mass.</p> |
