Definitions

  • the invention relates to a method for winding a continuously tapered Thread according to the preamble of claim 1 and a device for performing the method according to the preamble of claim 11.
  • the thread When winding a thread into a package, the thread is inside the Coil width at a substantially constant peripheral speed of the coil placed at a crossing angle on the coil surface. This is the thread by a traversing thread guide before running onto the bobbin surface inside a traverse stroke back and forth.
  • the length of the traversing stroke determines the coil width.
  • Differentiated methods of forming a coil In a first procedure the maximum length of the traversing stroke is not changed during the winding cycle. This will make a cylindrical cheese with a substantially right angle End faces wrapped.
  • the one set at the beginning of the winding trip Length of the traverse stroke is equal to the length of the traverse stroke at the end of the winding cycle.
  • the traversing stroke is during the winding cycle constantly shortened.
  • a cylindrical cheese is used sloping faces.
  • These so-called biconical coils are therefore to a normal plane, the slope angle is less than 90 °.
  • the traversing stroke set at the end of the winding cycle has a length which is less than the length of the traversing stroke at the start of the winding cycle.
  • the thread layers must be laid at the ends of the bobbin in such a way that no irregularities caused, for example, by exiting pieces of thread like that so-called thread cutters or sliding thread layers arise.

This ensures an even mass distribution to the Coil edges created so that no beads arise. This is when building a straight face after each breathing cycle the one set before breathing Length of the traverse stroke set again. When building a biconical After the breathing cycle, the coil becomes a slope angle Shortening of the basic traversing stroke set.
  • the invention is characterized in that all the layers of threads lying one above the other a package can be included in the design of the end faces.
  • the invention breaks with the prejudice that during winding up to produce the traverse stroke of a right-angled or inclined face of the coil is to be changed proportionally to the bobbin width during the bobbin travel. It was found that the formation of the end face of the cheese through not alone the lengths of the traverse stroke set during winding (winding travel) is determined, but rather by cooperation after completion of the coil of all layers of threads lying on top of each other. In particular Changes were found in the middle diameter range of the coil.
  • the lifting function gives the Relationship between the rewind caused by the winding time or the Coil diameter can be defined, and the lengths to be set in each case of the traverse stroke.
  • a certain length is assigned to each traversing stroke, the lengths of the Traversing strokes are smaller than the respective wound coil widths. So can the stroke function can also be viewed as a measure of the difference between the later spool width and the length of the traversing stroke.
  • rectilinear end faces serves a lifting function, in which at the beginning of the Winding travel a constant shortening of the traversing stroke relative to the bobbin width and at the end of the winding cycle, a constant extension of the traversing stroke relative to At the end of the winding cycle, a constant extension of the traversing stroke relative to the bobbin width is specified. The largest are in the middle Deviations between the spool width and the length of the traversing stroke.
  • the traversing stroke changes specified by the lifting function over the winding travel are essentially of the parameters such as thread tension Crimping of the thread, the thread titer, the bobbin density and the thread deposit, which is defined by the crossing angle and the thread reversal. So the connection has turned out, for example, a textured Thread with a relatively low crimp needs a lifting function, the larger one Deviation between the coil width and the length of the traversing stroke in shows the central area of the coil. In contrast, there is a winding of a coil with very high coil density, only a slight deviation between the coil width and the length of the traversing stroke.
