Abstract: The present invention is concerned with threading-in textile materials, such as a yarn, a roving or similar textile or filamentary material, into an enclosed duct or the like. The threading-in of the textile material is accomplished by manually operating a manual apparatus which functions as a pump. In this way there can be avoided the use of expensive and complicated devices presently provided for threading-in textile materials as is known. The invention is astonishingly simple, the manual apparatus is easy and convenient to use, readily transportable and its cost is exceedingly modest.

Abstract: The doffing of full bobbins built on spools placed on the vertical spindles of fly-frames equipped with revolving flyers is performed by combining gripping means such as resilient clips carried by each flyer with retaining means such as an annular groove formed at the upper end of each spool. The releasable axial coupling thus provided is capable of temporarily supporting a spool and full bobbin in the top position while the spindle is moved downwards in order to remove the spool.

Abstract: A free, rotating flyer is suspended from an arm hinged to the threadboard of a frame. The flyer is detachably connected to a flange which is positively driven by a timing belt. The flange coaxially surrounds the spindle.

Abstract: A fly winder capable of high speed operation comprises a hollow rotatable axially stationary flier and a rotationally stationary bobbin support concentric with the flier and axially reciprocable towards and away from an open end of the flier, the hollow interior of the flier being conical (that is to say stepless) and forming a wire guide, the greater diameter end of the hollow interior being disposed adjacent to the bobbin support and being of diameter such that a bobbin mounted on the support can be received therein, an eyelet being mounted on the flier at the greater diameter end of the cone and through which the wire is constrained to pass before being wound on the bobbin. Thus the wire enters the cone substantially on the axis of rotation of the flier and is free to assume its own position in the wire guide, which in practice tends to be a helix.

Abstract: In an improved system for lubricating flyer sheave bearings of a wire buncher or like machine, consisting of a collecting ring wherein the lubricant is deposited into grooves of this ring, and by centrifugal force is conveyed to the bearings of a sheave located on the outer periphery of a flying disc.In present day strand wire forming machines, sometimes referred to as "buncher machines", it is a common practice to employ grooved wheels or pulleys, referred to as "flying sheaves". These sheaves are mounted on the periphery of large, high velocity rotating discs or arms in which the sheaves are supported for rotation by bearings of one type or another. This design has created a serious problem in bearing performance, due particularly to the fact that an adequate system for keeping the bearings properly lubricated has yet to be found.

Abstract: A method and device are disclosed for cutting a rove at doffing in a flyer frame, wherein during the normal winding operation thereof the rove drawn out from front rollers is passed through the center hole of a flyer top, the hole of a hollow leg of a flyer, and over a presser and wound on a driven bobbin which is arranged on a bobbin rail moving up and down along the bobbin guide arbor of the flyer. Just before the doffing, the supply of the rove from the front rollers is failed and the bobbin and the flyer are caused to continue rotations substantially at the same speed for a time period sufficient to allow a predetermined number of rotations of both the bobbin and flyer, whereby the rove between the flyer top and the front rollers is subject to a stronger twist than that given during the normal winding operation. This assures that the rove is always cut of itself at an optimum portion thereof at the doffing.

Abstract: Method and apparatus to produce a dyed yarn package with qualities similar to that of a skein dyed yarn package. The method and apparatus incorporates a novel spindle onto which, preferably, high bulk yarns are wound under very little tension to provide a compact but loose yarn package which is amenable to efficient bulking and dyeing.

Abstract: This flyer bow is for a machine used for twisting together communication cable wires to make conductor pairs, or twisting together large numbers of wires. The bow has a recess into which the twisted wires can nest and be held by centrifugal force in a position away from the windage caused by the rapid rotation of the bow in an orbital path. This prevents a loop from forming in the twisted wires as sometimes occurs in machines where windage overcomes the centrifugal force and wire tension. This invention permits operation of twisting machines with lower wire tension.
