Abstract
Abstract To guide lamellae-like elements, such as needles, selector jacks and the like in knitting machines, and particularly circular knitting machines, the cylinder and dial portions are formed with grooves into which locating combs fit, the locating combs having bar-like support portions interconnected by comb-like partition bridges; separating liners, in which the lamellae are adapted to slide, are fitted between the comb-like partitions, and an adhesive casting compound is injected behind the separating liners, which are preferably formed with hook-like extensions to be anchored in the casting compound, and the locating comb, to secure the locating comb and the liners in position in the grooves of the machine structure.
