Abstract:
A process for knitting a weft-knitted fabric (T) composed of a base thread (FF) and a pile thread (Fp) mutually coupled, the fabric being composed of a succession of adjacent courses, said process being carried our in a machine having mutually opposite needlebeds and needles that are each axially slidable in a respective needlebed, each needle being provided with an end hook and a movable lever, said needles being operated in correspondence to a feeding of the yarn feed, said process comprising, for each stitch to be formed:effecting a forward movement of a selected needle (A8) of a first one of the needlebed from a position in which an old stitch of said yarn, belonging to a previously formed course (RI), is engaged with the selected needle (A8) to an upper run end position, and opening said lever of said selected needle (A8) by said old stitch during said forward movement of said selected needle (A8); engaging said selected needle (A8) with said yarn by means of said hook when said selected needle (A8) is in said upper end run position; effecting a backward movement of said selected needle (A8) from said upper end run position toward a lower run end position while closing said lever of selected needle (A8) in order to form a new stitch by inserting said yarn that is engaged with said selected needle (A8) inside said old stitch and to discharge said old stitch from said selected needle (A8); and while said selected needle (A8) is engaging said yarn, separating said pile thread (Fp) from said-base thread (FF), forming a loop of said pile thread and subsequently cutting said loop in order to create a cut pile, as the fabric under formation progressively moves transverse to said courses.
