A patterned pile fabric with uncut and severed pile loops is manufactured on a circular knitting machine in which pile elements (1) are arranged in a cylinder (C) provided with an upper and a lower pile forming ledge divided by a holding hook. For the knitting and pile forming action the pile elements (1) are individually selected and actuated at least to two different positions in which one of the alternative pile forming ledges is arranged between the needles (N). Pile loops drawn out over the upper pile forming ledges are cleared from the pile elements in the subsequent feeder by an additional clearing movement while pile loops formed over the lower pile ledge will remain on the pile elements. Those pile loops will slide downwardly along the stems of the pile elements by the subsequent knitting. In a continuation of the lower pile forming ledge the stems of the pile elements are provided with a cutting edge (1C) that will cooperate with a cutting edge (2C) of cutting elements (2) so that all pile loops coming to this continuation section are severed by a cutting movement of the cutting elements.

[ What is claimed is:] [1.] A method for manufacturing a patterned pile fabric having severed as well as uncut pile loops in one course of stitches on a circular knitting machine, the machine having latch needles (N) and pile elements (1) arranged at a right angle between said latch needles for forming pile loops, as well as cutting elements (2) cooperating with cutting ledges (1c) of said pile elements (1)arranging pile elements (1) in a cylinder C and individually controlling the arranged pile elements by controlling a plurality of pattern jacks (3) designed as double arm levers having upper and lower butts (3a and 3b), arranging two pile forming ledges (1u, 1v) to positions adjacent said pile element in a longitudinal direction for forming pile loops (Lc) to be severed and pile loops (Lu) to remain uncut in accordance with a pattern, feeding a pile thread (P) to one of said two pile forming ledges (1u, 1v), andforming pile loops (Lu) that are to remain uncut over pile forming ledges (1u) and clearing uncut pile loops (Lu) prior to the subsequent pile forming step by retracting the pile elements (1),said method including the further steps of maintaining the selected pile forming positions of the actuated pile elements (1) thereby controlling the pile elements (1) with respect to their subsequent retracting motion when the pile loops are cleared from the needle latches, andarranging the cutting ledges (1c) at such a spacing below the latch needles (N) such that said pile loops (Lc) to be severed will slide onto said cutting ledge (1c) only after knitting at least one more course of stitches.
