Abstract: A method for twisting a pair of moving strands uses a winder assembly 510, which is mounted on a first shaft 140 and rotates around a cylindrical drum 110. Twisted wire is wrapped in adjacent convolutions around an exterior surface of the cylindrical drum, which is mounted on a second shaft 150. The exterior surface is energized to advance the convolutions from its input end to its output end; and an unwinder assembly 520 is mounted on a third shaft 160 at the output end of the drum. The shafts are coaxial with each other and each is capable of independent rotational movement. The volume of strand material stored on the drum may be varied by changing the relative rotational speeds and directions of the different shafts. A twist in one direction is imparted onto the strand pair when the number of convolutions stored on the drum is increased; and a twist in the opposite direction is imparted onto the strand pair when the number of convolutions stored on the drum is decreased.

Preferably, before lowering the packages (9), a reserve of roving (5) is created by slowly rotating the flyers (6) and packages (9) through a few revolutions, to simultaneously twist the roving (5) and strengthen it.

Abstract: A spinning apparatus winds a strand onto a yarn package by relatively rotating a flyer and the yarn package about an upright axis so as to wind the strand in a succession of turns around the package by a flyer finger movable axially relative to the package. Each successive layer of turns is shorter than the preceding one so that the finished package has an axially upwardly tapered upper end. After substantially completely forming the package the rotation is generally stopped to leave the flyer in a position with the finger below the upper end of the last layer of turns formed on the package. Then the package and finger are relatively axially moved until the finger is generally at the upper end of the first layer of turns formed on the package. The flyer and package are then relatively rotated forward, that is in the same direction as when the package was being formed, through at least one half revolution about the axis so as to form a loop of the strand around the upper package end.

The funnel can contain a guide portion projecting interiorly of the funnel at a spacing from the entry channel and a neck portion in which the entry channel is formed.

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.

Abstract: Disclosed is a spooling apparatus that can be threaded on the fly to anchor, controllably twist and wind filament onto a receiving spool. A receiving spool is non-rotatably mounted on a spool shaft for axial reciprocation. A lead-in pulley, whose rotational axis is perpendicular to the receiving spool axis, is spaced axially outboard with respect to the receiving spool. A flier is mounted to rotate concentrically about the receiving spool and presents a pick-up head adapted to engage the feed run of the filament as it passes between the lead-in pulley and an orienting pulley located in proximity to the inboard end of the receiving spool. The orienting pulley is canted such that the tailing run of the filament cannot be engaged by the pick-up head as it rotates with the flier although the canting of the orienting pulley disposes the feed run such that it will be engaged by the rotating pick-up head when the spool reaches a predetermined position along its range of axial reciprocation.

Abstract: Herein disclosed is a double twisting machine of flyer type, which comprises a pair of rotatable fliers, a pair of bow guides formed with a through bore for allowing wire elements to pass therethrough, two pairs of guide holders each retained in one end of each of the fliers for holding one end of each of the bow guides, and two pairs of shock-absorbing elastic members each interposed between each of the fliers and each of the bow guides through the corresponding one of the guide holders. The fliers are in spherical contact with the guide holders so as to assure smooth swinging motions of the bow guides.

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.
