  • Patent number: 4408731
    Abstract: With the creel for a spinning machine according to the invention at least two rows of rotatably suspended roving bobbins, which extend essentially in parallelism with respect to one another, are adjacently lined-up. Normally in ring spinning machines there are employed for such creels roving deflecting rods which extend horizontally in the longitudinal direction of the ring spinning machine. The rovings extending from the roving bobbins to the drafting arrangements are guided around the deflecting rods for the purpose of guiding the rovings. If the deflecting rod is located behind the bobbins, then insertion of the rovings about the rods is extremely cumbersome, and additionally, there exists the danger of damaging the rovings. If the deflecting rod is located further towards the front, then exchange of the bobbins becomes tedious. These drawbacks are eliminated with the invention in that a row of substantially rod-shaped holders is arranged behind the front row of roving bobbins.

  • Patent number: 4365468
    Abstract: The false twist machine has a texturing part arranged below heat treatment zones in which three supply devices and a false twist device are superimposed and staggered from the back to the front in such a manner that in threading in of the thread into these devices turning about and overhead working processes of the operator are avoided. The thread paths formed by the threading in are placed one in front of the other in the sequence of the threading in process. A bobbin creel is movable to the texturing part and is equipped with a thread transfer device which transfers the threads coming from the individual creel bobbins into the vicinity of the first supply device. The winding device is arranged opposite the texturing part at a distance forming an operating alley and gives off the full bobbins to the outerside of the winding device opposite the operating alley. The empty bobbins can be moved from the machine end into a readiness reserve position.

  • Patent number: 4311916
    Abstract: A travelling scanning apparatus for successively checking the working conditions at the spinning position of a ring spinning machine is enabled, in order to determine whether a yarn breakage has occurred at a spinning position, and, in the affirmative case, whether there prevails a danger of damage due to lap-up formation on a roll of the drafting arrangement. Using a yarn feeler first the presence of a normally spun yarn is detected. If no yarn is present, the broken yarn suction nozzle, which is used for eliminating the fibres not spun in, is lowered from its normal working position into a scanning position, and an optimum fibre stream is obtained between the delivery rolls of the drafting arrangement and the lowered nozzle for scanning using a second feeler. In case of non-presence of this fibre stream, that is in case possible lap-up formation, a roving supply interrupting device is activated and the roving supply to the drafting arrangement is interrupted.

  • Patent number: 4235393
    Abstract: A method of, and apparatus for, taking-off a thread or the like alternately from one of two bobbin packages arranged side by side in a creel for textile machines. The method contemplates taking-off a thread from a bobbin package, the tail end of such removed thread being knotted to the lead end of an essentially parallelly arranged reserve bobbin package. The knot is formed by first pulling the leading thread end of the reserve bobbin package through a thread take-off opening operatively associated with such reserve bobbin package. Then the thread is pulled in a direction opposite to the thread take-off direction through or at a location near a take-off opening operatively associated with the bobbin package from which thread is in the process of being removed, in other words the momentary withdrawal bobbin package.

  • Patent number: 4171201
    Abstract: A moveable thread guide element is disposed for movement from a thread receiving position located below a stationary thread guide pin element to a thread-transfer position engaged with the pin element. The moveable thread guide element is pivotally mounted so as to pivot upon engagement with the pin. This allows the thread on the moveable guide element to slide onto the pin element. After transfer, the moveable guide element can be lowered.
