with a combined thickness substantially the same as the overall thickness of one of the control members application_number US 46943790 A description in fig1 the control of one warp thread 110 is shown but it will be appreciated that as the machine is a selvedge machine typically 56 or 64 warp threads at the edge of a cloth are controlled by adjacent mechanisms the lower portion of the control illustrated in fig1 corresponds generally to that portion of a known machine in that the warp thread 110 passes through a heald eye 114 attached to a heald wire 116 the lower end of the wire 116 is biased downwardly by a spring 118 and the wire extends upwardly and passes around a floating pulley 120 the wire is fastened to a fixed mounting 122 a floating pulley 124 is connected to and suspends the pulley 120 and a loop 126 passes under the pulley 124 one end 132 of the loop is secured to a first disc 134 and the other end 136 of the loop is secured to a second disc 138 both of the discs 134 and 138 have an inner circular opening 140 shown in fig2 and 4 through which an axle 142 passes that axle being common to the other discs controlling the other warp threads.
