Abstract
There are provided a movable sinker apparatus of a weft knitting machine and a sinker which are capable of holding and pressing down a knitting yarn of a previous loop and sufficiently pulling down a knitting fabric. At forward positions of the sinkers, second protruding portions are close to each other, and thus a knitting fabric can be sandwiched therebetween. When the front and rear needle beds are faced each other so as to be symmetric at the needle bed gap, the forces of the wire springs are applied so as to pull down the knitting fabric in the vertical direction. A knitting yarn receiving portion is formed on a first protruding portion of the front end portion on the sinker, and thus it is possible to retain a knitting yarn of a previous loop and prevent the knitting yarn from moving as the knitting needle moves forward. the second protruding portion that projects outward in a radial direction is formed on a portion close to a front end of the first protruding portion, and the knitting fabric can be sandwiched and pulled down by the second protruding portions provided on the needle beds that are opposed to each other.
