Abstract
Abstract The ribbon-type fabric is provided with weft-yarn loops inserted at both sides of the run of the warp yarn, the weft-yarn loops being held together at the two edges of the ribbon-type fabric by at least one auxiliary yarn. In order to avoid that the joints of the weft-yarn loops are visible to the exterior, the auxiliary yarn will run parallel to the weft-yarn loops over at least a part of the width of the ribbon-type fabric. The auxiliary yarn is tied-off in itself or by means of an additional auxiliary yarn.
