Abstract
In an arrangement for producing packages used as feeding packages for a subsequent twisting operation and containing two yarns wound up side-by-side, it is provided that the yarns are monitored with respect to a yarn breakage and, in the case of the occurrence of a yarn breakage, are cut and connected with one another at a common point before moving onto the package.
Claims21
Apparatus for producing feeding packages containing two yarns wound up side-by-side as a double yarn for a subsequent twisting operation, said apparatus comprising:
- drafting means for drafting two slivers,
- prestrengthening means arranged downstream of said drafting means and including means to form two separate prestrengthened yarn components from the respective slivers,
- yarn guide means for guiding the yarn components disposed in side-by-side relationship,
- withdrawing means for withdrawing the double yarn from the yarn guide means,
- winding means for winding the double yarn supplied by the withdrawing means onto a spool package,
- cutting means for cutting the two yarn components at a similar position along the length thereof,
- connecting means for connecting the cut yarn end portions preliminary to their being wound onto the spool package by the winding means,
- and monitoring means for monitoring the two yarn components with respect to yarn quality deterioration, said monitoring means being operable to signal operation of the cutting means and the connecting means in response to detection of unacceptable quality of one of the yarn components, wherein said cutting means is disposed downstream of the monitoring means to thereby assure simultaneous cutting of the two yarn components at the similar position with resulting disposition of cut ends of both yarn components at a common location on the spool package.
