摘要： An underwinding thread clamp for a spindle of a ring spinning or ring-twisting machine has a clamping sleeve biased by a spring against and juxtaposed with a collar on the spindle. The juxtaposed surfaces of the spindle and collar have wavy contours so that, upon engagement of an actuating member with each collar, the latter is cammed into its open position to release the respective underwinding thread so that the latter, engaged when a full bobbin was removed, can be released. The clamping of the underwinding thread permits the thread to be wound on the newly mounted core sleeve.

摘要： A yarn cutting apparatus comprising a cutter body, piston and a cutting mechanism. The cutting body has a cylindrical bore extending from a first end to a second end and a body notch extending transversely from one side to the other side of the cutter body. The cutting mechanism comprises a first cutting element, having an element notch and a planar support surface and a planar cutting surface parallel with the support surface, slidably mounted in the cutter body to move within the cylindrical bore and a second cutting element resiliently mounted in the cutter body adjacent the body notch. The second cutting element has a cutting edge and a planar surface that is parallel with and in surface to surface contact with the planar surface of the first cutting element. The piston is slidably fitted into the bore and engages an end of the first cutting element adjacent the first end of the bore, while the opposite end of the end of the first cutting element is attached to a bearing element slidably fitted into the bore. The cutter body further includes a support attached adjacent to the body notch and opposite the second cutting element for engaging the planar support surface of the first cutting element to resist rotation of the first cutting element due to the urging of the second cutting element.

摘要： The instant invention is a reserve-surface cleaner used on a longitudinally extending row of spindles rotatable about respective parallel axes lying in a common longitudinal plane and each having an upper package-forming region, a lower reserve surface, and a contact surface centered on the axis. The cleaning apparatus has a carriage displaceable longitudinally along the row parallel to the plane past the spindles, a blade mounted on the carriage and having an edge juxtaposable with each of the reserve surfaces as the carriage moves along the row, and a spacer mounted on the carriage, fixed thereon relative to the blade, and engageable with the contact surfaces of the spindles as the carriage moves along the row. A spring urges the spacer and blade transversely of the plane toward the spindles so that as the spacer wears a transverse spacing between the blade and the reserve surfaces decreases. A sensor unit detects the transverse spacing between the blade and the reserve surfaces and a controller emits an output when the detected transverse spacing falls below a predetermined threshold.

摘要： 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. Slack is then created in the strand upstream of the package and the finger is moved downward below the level of the upper end of the outer layer. Finally the strand is cut below the level of the upper end of the outer layer.

摘要： During the cop-forming phase of operation of a ring spinning or twisting machine, yarn is wound onto spools carried by the spindles in order to form cops. At the end of this phase, the yarn associated with each spindle is fastened below the spool by means of several fastening turns; thereafter, the full cops are removed with breakage of the yarns. In order to facilitate the operation of cop-removal means for automatically and simultaneously removing all of the full cops, yarn-severing means are provided that sever the yarns prior to the cop-removal means picking up the full cops. In a preferred embodiment, the yarn-separation means is arranged to snap the yarns by downwardly displacing the members around which the fastening turns are wound.

摘要： Apparatus for piecing a thread end in an open-end spinning unit having a spinning rotor with a ring of open-up fibers including opening means having friction tool means for fraying the thread end at a predetermined location and a device for returning the thread end into the spinning rotor after fraying thereof by the friction tool means. Preferred embodiments of the friction tool means include rotatably mounted friction tool members as well as non-rotatably mounted friction tool means. The friction tool means have roughened surfaces in the form of a file in some embodiments, while having brush like surfaces in other embodiments. Various means are provided for adjusting the position of the friction tools and for operating same to effect roughening or fraying of the thread, including surfaces designed to effect a severing of the thread after a preliminary roughening. Clamping devices are also provided for clamping the thread at opposite sides of the friction tool, which clamping devices are movable with respect to one another to effect severing of the thread after being frayed.

摘要： A thread is wound onto a carrier which is mounted on a rotatable support, until a package of predetermined size is formed on the carrier. Thereupon a plurality of terminal convolutions of the thread are taken about the rotatable support before the carrier with the package is removed from the support and the thread severed intermediate the carrier and the terminal convolutions. A new carrier is now mounted on the support and thread is again wound on the new carrier to form a package thereon; as the formation of the package on the new carrier proceeds the terminal convolutions are concomitantly abraded during rotation of the new carrier until they are worn through and separate from the support before the new package is completed and new terminal thread convolutions are taken about the support. An apparatus for carrying out this method is also disclosed.
