Abstract
In the case of a process for piecing at a spinning unit that is used for producing feed spools consisting of multiple-wound, prestrengthened slivers for a subsequent twisting operation or the like, it is provided that first the supply of the drafting roller device is started, after which the slivers are sucked into the pneumatic false-twisting devices, are guided through them and are then jointly gripped at the outlet of the false-twisting devices, are placed in a withdrawal device and are then fed to a winding-up device.

A piecing process for piecing prestrengthened slivers formed in a unit of the type having drafting roller means for supplying a pair of drafted slivers, pneumatic false twisting means for forming prestrengthened slivers from the pair of drafted slivers, prestrengthened sliver withdrawing means for withdrawing the prestrengthened slivers from the false twisting means and joint sliver wind-up means for jointly winding up the pair of prestrengthened slivers to form feed spools of multiple wound prestrengthened slivers which can be used in subsequent twisting operations or the like to form commercially usable yarn, said process comprising the sequential steps of
- starting the supply of the pair of drafted slivers by the drafting roller means,
- inserting the pair of drafted slivers into the false twisting means,
- jointly gripping the pair of slivers at the outlet end of the false twisting means, and
- inserting the slivers into the withdrawing means where they are fed to the wind-up means.
