    (57) The amount of vertical movement imparted to the needles (1a) during stitch loop formation is reduced by supporting special types of sinkers (8) for movement in a radial direction and along an inwardly and downwardly inclined path of travel (7a) relative to the needles (1a). As the needles (1a) are raised to the latch clearing level the sinkers (8) are moved inwardly and downwardly to lower the level of the stitch forming ledge (8a) thereof so that the amount of vertical upward movement of the needles (1a) is reduced. As the needles (1a) are then lowered to stitch drawing level, the sinkers (8) are simultaneously moved outwardly and upwardly to raise the stitch drawing ledge (8a) so that a portion of the length of the stitch being formed is determined by the amount of downward movement of the needle (1a) and the remaining portion of the length of the stitch being formed is determined by the amount of upward movement of the sinkers (8).
