摘要： The process and device for setting optimal piecing parameters in the spinning machine when changing batches includes entering and storing in a memory of a central machine computer spinning machine data relevant to the piecing operation. At the start of the piecing operation, the machine data is transmitted from the central machine computer to a microcomputer of a piecing device. The microcomputer contains a piecing program and a database of piecing parameters pertaining to the piecing process. An optimal set of piecing parameters is computed with the piecing program in the microcomputer. The microcomputer incorporates the spinning machine data and computes from the database an optimal basic set of piecing parameters. The optimal set of piecing parameters is displayed at an optical display unit associated with the microcomputer and can be manually adjusted.

摘要： A process and device for piecing in an open-end spinning device includes switching on a fiber feeding device for a predetermined period of time so that fibers which are undesired for piecing are combed out of the leading end of the fiber sliver which is presented to an opener device. The combed out fibers are deflected from the fiber collection surface. The fiber feeding device is switched off after the predetermined period of time once the undesired fibers have been combed out and is maintained in an off condition for a short period of time so that the fibers remaining in the leading end of the fiber silver are only minimally damaged by the opener device. The fiber feeding device is switched back on and the fiber stream is deflected from the fiber collection surface as the stream increases to full strength. The fiber stream is subsequently deflected to the fiber collection surface for piecing in coordination with backfeeding of a yarn end to the fiber collection surface.
