Abstract
In a process and apparatus for spinning a package with a double yarn, which is used as a feed package for a subsequent twisting operation, it is provided that, when one or both fed slivers run out, an automatic splicing of new slivers is carried out.
Claims28
A spinning process comprising spinning first and second yarn components at a spinning unit from respective first and second slivers, and guiding said first and second yarn components together to form a double yarn to be wound together as a feeding package for a subsequent twisting operation, said process further comprising the sequential steps of:
- feeding first and second slivers to the spinning unit to be spun,
- detecting interruption of the feeding of at least one of the first and second slivers to the spinning unit,
- severing the first and/or second slivers such that the two old sliver ends are offset with respect to one another in the travel direction of the slivers being fed to the spinning unit,
- and connecting the old sliver ends of the first and second silvers with respective new sliver ends, thereby forming respective first and second slivers with respective connections which are spaced from one another in the travel direction of the slivers.
A spinning process comprising spinning first and second yarn components at a spinning unit from respective first and second slivers with the first and second yarn components being guided together to form a double yarn to be wound together as a feeding package for a subsequent twisting operation, said process further comprising the sequential steps of:
- feeding first and second slivers to the spinning unit,
- detecting interruption in the feed of at least one of the first and second slivers,
- severing the first and/or second slivers such that the two old sliver ends are disposed side-by-side with respect to one another in the travel direction of the silvers being fed to the spinning unit,
- connecting the old sliver ends of the first and second slivers with respective new silver ends, thereby forming respective first and second slivers with respective connections which are disposed side-by-side in the travel direction of the slivers, and
- subsequently removing the connections from the yarn components being wound together on the feeding package.
Sliver splicing apparatus for a spinning unit for spinning first and second yarn components from respective first and second slivers with said first and second yarn components being guided together to form a double yarn to be wound together as a feeding package for subsequent twisting operations, said spinning unit including feeding apparatus for feeding first and second slivers to a spinning unit,
- said sliver splicing apparatus comprising:
- detecting apparatus for detecting interruption in the feed of at least one of the first and second slivers,
- severing apparatus for severing at least one of the first and second slivers such that the two old sliver ends are offset with respect to one another in the travel direction of the slivers being fed to the spinning unit,
- and connecting apparatus for connecting the old sliver ends of the first and second slivers with respective new sliver ends, thereby forming respective first and second slivers with respective spliced connections spaced from one another in the travel direction of the slivers.
