Abstract: Winding apparatus for the continuous winding of an advancing strand, having two coaxially mounted, spaced and independently driven, removable reels and a traverse mechanism for delivering strand to the reels alternately. Each of these reels is mounted on an axle which is equipped with a machine reel and snagger means assembly which is a permanent part of the machine and each of them are mounted adjacent to the remote ends of said reels when said reels are in winding position so that the reels are disposed for rotation about a common axis between the machine reels and snagger means assembly. The traverse means is controlled so as to distribute the strand onto one of the reels until a predetermined length of strand is wound thereon. Further means is provided for rapidly moving the traverse means across the empty reel into a position for directing the strand onto the machine reel associated with the empty reel.

Abstract: In gripper shuttle looms for a shuttle box which contains a groove for receiving a gripper shuttle and which rotates 180.degree. to turn the shuttle around and has a braking member which cooperates with the groove to check the shuttle in the groove, and wherein said braking member moves away from the groove to permit the shuttle box to be turned and the shuttle to be picked: restraining means located in the groove for restraining the shuttle against lateral movement along the longitudinal axis of the groove during the shuttle box turning motion and which maintains the shuttle in the proper position in the shuttle box and allows the shuttle to be picked out of the shuttle box.

Abstract: A projectile for use in an outside filling supply loom in which at least a portion of a filling pick is inserted into the projectile prior to each weft insertion. The projectile comprises a weft storage chamber having an inlet opening at one end through which the filling is inserted into the chamber, an outlet opening at the opposite end of the projectile and an air passageway from the storage chamber to the outlet opening which by-passes the filling stored within the chamber so that airflow between the inlet and outlet ends does not affect the filling stored within the chamber.

Abstract: Fluid treatment apparatus for textile fibrous material comprising a duct, a portion of which is enlarged to form a fiber treating chamber which includes an outlet opening, an inlet opening and a central passageway which extends between the openings and which has a surface which extends from a first point on the periphery of the inlet opening to a second point on the periphery of the outlet opening and extends no further from the longitudinal axis of the central passageway than the first point so that the surface is wiped by fiber entering the central passageway to prevent the accumulation of moisture near the inlet opening.

Abstract: Air-cooling apparatus for a heat-exchange jacket which surrounds the outside of a vertical extruder barrel. The apparatus comprises a hood which surrounds the jacket and includes a plenum chamber at one side of the jacket, an outlet opening at the opposite side of the jacket and a restricted inlet opening between the jacket and plenum chamber wherein the hood provides a through-passage between the inlet and outlet openings. Means are provided for forcing air into the plenum chamber to create a super-atmospheric pressure therein and provide an air flow through the through-passage. The hood also includes an outlet chamber adjacent the outlet opening which has the same vertical cross-sectional configuration as the plenum chamber to provide a balanced air draft condition on opposite sides of the heat-exchange jacket.

Abstract: A black dyestuff composition useful for heat transfer printing of polyester textile which is made up of a compatible mixture of a brown azo dye and a blue anthraquinone dye.

Abstract: Method of and apparatus for preparing a length of weft yarn in a magazine for insertion in a shuttleless loom. Weft yarn is drawn from a supply package into a storage magazine wherein a helical airflow is created which directs the weft yarn into a helix from which the weft yarn is then withdrawn axially of the helix for insertion into the loom.

Abstract: A spreader roller for textiles which is fabricated by positioning a smooth cylindrical supporting member coaxially within a corrugated tube having inner and outer helical ridges, the outer ridges on one longitudinal half of the tube being of opposite hand to the outer ridges on the other half of the tube. The corrugated tube is fastened to the supporting member along the inner helical ridges, preferably by plug welding at spaced points along the inner ridges.

Abstract: Screw removing apparatus for vertical extruders wherein the screw is removable through the bottom of the extruder barrel, the apparatus including an adaptor for attaching to the upper end of the screw, a winch for fastening to the adaptor and which includes a yieldable locking means which enables the winch to support the weight of the screw and which yields upon application of a predetermined downward force to the adaptor which is sufficient to overcome the yieldable locking means.

Abstract: A packaging machine which includes article buckets and leaflet clamps mounted on the buckets, each clamp having a spring loaded jaw which, in the open position, allows a leaflet to be inserted between the jaw and bottom plate of its respective article bucket, and, in the closed position, is effective to clamp a leaflet between the jaw and bottom plate to deflect a portion of it into the exit end opening of the bucket. Means are provided for opening the clamp jaw, inserting a leaflet between the open clamp jaw and bottom plate, closing the clamp jaw to clamp the leaflet and opening the clamp jaw to allow the leaflet to be carried into a carton by the article as it is transferred from the article bucket to the carton.

Abstract: Means for and the method of expanding and transferring a carton from a stack of collapsed cartons in a magazine to a bucket on a conveyor wherein the collapsed cartons are extracted singly from the magazine first by a suction means and transferred to a second suction means which deposits the carton into the conveyor bucket. The cartons comprise at one end thereof two side flaps and a front flap which includes a tuck flap. Stationary cams are utilized to partially expand a carton while it is being transferred and pushing the front flap inwardly while the carton is partially expanded which spreads one of the side flaps outwardly. This side flap is then held while the front flap is released and the other side flap and front flap are spread outwardly from the inside. Finally, all the flaps are maintained in a spread position while the carton is fully expanded.
