cage and ring 40 40a these turns become gradually tightened and slide along the edges of the plate 47 to form tight turns on its extension 49 in this manner turns or coils of effect yarn are formed as indicated at e1 this arrangement gives a fancy yarn of the so called boucle or flocked chenille type cf i e with uncut coils of effect yarn as shown in fig6 and 8 the turns leave the winding member 16 below the end of the extension 49 the machine is also equipped to produce a special fancy yarn as shown in fig9 this yarn comprises portions x of flocked chenille boucle produced in the aforesaid manner interspaced with portions y of normal chenille cn i e with individual sheared lengths of effect yarn this is obtained by providing a cutting blade with is made periodically active and inactive for this purpose a rotatable disc shaped blade 60 mounted on a movable support 62 on which there is also mounted a motor 64 for driving the blade 60 the support 62 is preferably mounted for rectilinear sliding movement and is controlled by a cylinder 66 which can displace the support 62 between an inactive position in which the blade 60 is remote from the member 16 fig6 and 8 and an active position in which the blade 60 enters the narrow slot 49b provided longitudinally in the surface of the extension 49 opposite the.
