ABSTRACT:
A needle assembly for use in a knitting machine, particularly circular and flat knitting machines having one or more working systems and one or two working needle beds, the needle comprising a casing body of elongated rectangular form with a groove in its upper two-thirds portion, the head of the needle forming a hook for picking up the thread and the body having a cross-section of elongated U-shape at the groove. In the interior of the groove there is slidably arranged a plate likewise of rectangular and elongated form and provided with a lug projecting laterally from the body of the needle. The needle is provided at its lower portion with a lug for co-operation in the course of its passage on the cams of the working system of the machine during its needle raising and lowering action, the plate likewise co-operating by its lug with positioning stops of the working system of the machine in respect of the opening and closing, as necessary, of the hook of the needle. The stroke of the plate is limited by travel end stops of elongated form disposed in the mouth of the grooved recess of the needle body at upper and lower parts of the mouth, defining a free path for the sliding of the lug of the plate.
