Abstract: A supply spool supplies a weft thread through an adjustable actuated thread brake and a thread tension sensor to a weft thread accumulator, from which an accumulated insertion length of the thread is provided to a weft insertion device. The tension sensor provides a measured actual thread tension signal to a control arrangement, which compares the actual tension to a selected rated tension, and, dependent on the deviation therebetween, provides a control signal to an actuator of the thread brake, so that the actual thread tension constantly corresponds to the selected rated tension. Another sensor provides a signal indicating a change from an empty spool to a full spool. Responsive thereto, the control arrangement actuates the thread brake to an adjustable starting brake setting as a coarse adjustment. Then the self-regulating fine adjustment is continued. A constant winding tension and thread accumulation length are achieved in the thread accumulator.

Abstract: A yarn delivery system including a trolley creel and a yarn guide apparatus. The trolley creel is made up of a plurality of independently moveable trolleys and each includes a set of rotatable yarn packages. When each trolley is moved into place, the yarn guide apparatus is vertically spaced therefrom. As yarns are drawn vertically from the creel, the yarn guide apparatus vertically guides them.

Abstract: A quick change assembly for a tire cord fabric loom utilizes a pattern of warp ends which are threaded through suitable harnesses. The pattern in the harnesses is placed in the loom and the individual warp ends are pulled back to a plurality of creel combs which are secured to the creel and which each receive and guide a group of warp strands from the creel. These warp strands are directed to the loom and are formed into the tire cord fabric having the desired pattern.

Abstract: In a system for exchanging packages on a textile machine such as a rewinder, a creel loader receives empty packages from a creel for transportation to the position of a package supporter, the package supporter is rotated about a vertical axis over 180 degrees to place full packages in a position facing the creel loader, and, after receipt of the full packages, the creel loader travels to a section of the creel in need of package exchange for transfer of the full packages to the creel. Concurrently with this process, full packages from a package stocker is mounted to the package supporter by operation of an assistant device such as a robot for next exchange of packages with the creel loader. Loss in production efficiency otherwise caused by empty travel of the loader is well avoided.

Abstract: In order to make the loading operation on a bobbin creel simpler, a fitting pattern is stored for each kind of bobbin in a control means (21). The individual fitting patterns can be sequentially called up as output signals. Those output signals either activate signal elements which are associated with each mounting device (14) at the bobbin creel (3) or they serve directly for controlling an automatic loading apparatus.

Abstract: A method of converting a warping arrangement having two creel halves and a warper from a setup for long lots of one style to a setup for shorter lots. The method includes converting transfer package positions on each of the creel halves to running package positions and providing a yarn sheet transfer device associated with each creel half to permit the recreeling of each creel half by placing leading ends of newly recreeled yarn packages into yarn guides on the yarn sheet transfer device associated with the creel half while yarns from the other creel half are running to the warper through a yarn sheet transfer device associated with the other creel half.

Abstract: An apparatus for supplying packages to a warper creel having a plurality of package supporting pegs comprises a lining station for lining up packages transported on a conveyor in a predetermined order, and a package exchanging apparatus located between the lining station and the positioned creel for transferring a plurality of packages lined up at the lining station collectively to the pegs on the creel.

Abstract: A creel is used with a winder having a predetermined width and operable to draw in across this width in a normally horizontal longitudinal transport direction a warp of filaments from respective bobbins. The creel comprises a support frame having respective supports for the bobbins and having a pair of generally like sides each provided with a respective half of the supports. The sides are elongated in the transport direction and have downstream ends spaced by at least the winder width, upstream ends more closely spaced, and inner faces turned transversely inward toward each other. Respective deflectors on the inner faces of the support sides guide the filaments inward and transversely of the transport direction from the respective supports and then longitudinally in the transport direction to the winder. The filaments normally run from the deflectors to the winder without touching any substantial guide structure.

Abstract: A creel assembly and section beam pallet minimize downtime, enhance loading and unloading operations and facilitate automation, in slasher, dyeing, and like textile operations. First and second creels are mounted side-by-side on a frame. Air bearings lift the frame off of the floor, and a powered wheel rotates the frame 180.degree., when changing over from the section beams on one creel, to the other. The section beam pallets include outwardly extending arms having shoes on their bottoms. The shoes cooperate with rails associated with the support frame, and air is delivered between the rails and the pallet shoes when it is desired to move the pallets along the rails. The rails are tilted from a level position to a slightly downwardly inclined position so that the pallets glide on air to the end of the rails, at which position they may be unloaded with a forklift or an automated guided vehicle.

Abstract: A method and system for facilitating a continuous and automated taking-off of yarn from yarn packages. A creel module having one or a plurality of yarn package receiving creel pins disposed in one or more rows is automatically loaded with yarn packages at a loading position. The loaded module is conveyed, optionally through a buffer storage system, to operative association with a stationary creel frame. The module is transferred from the conveying mechanism to the creel frame, and is mounted with respect to the creel frame so that the yarn may be taken off the packages thereof. After the yarn from the module packages has been exhausted, the module is removed from the creel frame and conveyed back to the loading position, while it is replaced with another, loaded, module.
