Abstract: In a high speed circular warp thread knitting machine latch needles are reciprocated in respective, vertical tricks in a stationary cylinder by a cam rotating around the cylinder thereby to engage warp threads drawn down from above. A presser plate rotating with the cam deflects each warp thread in turn across a needle while the latch of the latter is open. According to the invention each warp thread descends uninterruptedly to a respective needle trick from an eyeleted disc at an acute angle to the vertical and the presser plate has a leading surface which extends forwardly and toward the cylinder at an acute angle to a radius of the cylinder. In a preferred embodiment a wire latch guard extends forwardly from and moves with the presser plate so that its free end is positioned to obstruct closing movement of the latch of a rising needle just as the latch is released by casting off the previously formed loop of thread onto the shank of the needle.
