Tufting needle and method of making a tufted pile fabric

Abstract From the Canadian patent

A method of making a tufted pile fabric includes the step of simultaneously throwing a loop of each of first and second pile yarns which are threaded through a needle having a pair of vertically spaced eyes with the first yarn threaded only through the lower eye and the second yarn threaded through both eyes. The reciprocatory movement of the needle is controlled such that the upper eye of the needle does not pass through or enter the backing fabric. The pile yarns extend through the lower eye in the same direction. In other words, the yarn runs leave the lower eye at the same side of the needle. The run of pile yarn between the eyes is disposed within a yarn guide groove. Because the feed …
