Abstract: A fluid flow suppressor for use with a number of running threadlines comprising a pair of plates which are rotatable about a common axis substantially parallel to the threadlines, the plates being provided with apertures through which the threadlines may be threaded when the apertures are superimposed and a number of slots corresponding to the number of threadlines, the slots in one of the plates opening into the right hand side of the aperture in that plate and the slots in the other of the plates opening into the left hand side of the aperture in that other plate, the slots being so disposed that on rotation of the plates they superimpose on each other.

Abstract: A yarn winding apparatus of the type for winding yarn on cores comprising a drive roll; a rotatable head carrying on one side thereof two chuck carriers and chucks for holding cores, projecting from the rotatable head at right angles, the axis of the rotatable head being offset from the axis of the drive roll such that the carriers and chucks are wholly disposed on one side of the drive roll and the rotatable head being carried on a shaft which extends only from the side of the head opposite the carriers and chucks, the chuck carriers being carried on guide rails mounted on said head, the guide rail for one chuck carrier being laterally spaced to one side of the head axis, and in a plane perpendicular to the head axis, while the guide rail for the other chuck carrier is laterally spaced to the other side of the head axis, also in a place perpendicular to the head axis, the guide rails being long enough to allow the chuck carriers to pass over and under the rotatable head axis and to pass each other, to allow
