Abstract: The invention relates to a method, a knitting machine and sinkers (1, 2) for producing plush fabrics. The method is distinguished in that core and plush thread loops (48, 54) are preformed on selected sinker edges and are transferred prior to the actual stitch formation from these sinker edges to other preselected sinker edges by simple displacement of the sinkers (1, 2). For this purpose the knitting machine has first and second sinkers (1, 2), wherein the second sinkers (2) are provided with oblique faces (15). These are used, in the course of the transfer of the core thread loops (48) by means of retracting the first sinkers (1) and simultaneous advancement of the second sinkers (2), to act on the core thread loops (48) in such a way that the latter are securely enclosed in the slits of the first sinkers (1) when these are again advanced (FIG. 10).
