Abstract
Abstract Servicing apparatus, such as rotor cleaning and yarn piecing apparatus, for servicing individual spinning assemblies of open-end spinning machines is provided. In order to accommodate usage of a single servicing instrument for several different spinning machines, operating at different conditions for producing different yarns, program control apparatus, including a plurality of control programs which are distinguished from one another as the sequence and timing of servicing operations, is provided. In preferred embodiments, the spinning machines include switch setting apparatus for switching the servicing instrument to the proper program in response to movement of the servicing instrument adjacent the spinning machine to be serviced.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
118 words
Servicing apparatus for a plurality of spinning machines comprising: servicing means for servicing spinning assemblies of the spinning machines, said servicing means including function elements for carrying out servicing operations, moving means for moving said servicing means to respective servicing positions adjacent the respective spinning assemblies to be serviced, program control means for controlling switching sequences and switching times of drives for said function elements, said program control means including a plurality of control programs which are distinguished from one another as to switching sequence and/or switching times, whereby different spinning machine operating conditions can be accommodated by said servicing means, and program switch control means for switching said program control means from one control program to another.
Claim 2
Dependent Claim
118 words
Servicing apparatus for a plurality of spinning machines comprising: servicing means for servicing spinning assemblies of the spinning machines, said servicing means including function elements for carrying out servicing operations, moving means for moving said servicing means to respective servicing positions adjacent the respective spinning assemblies to be serviced, program control means for controlling switching sequences and switching times of drives for said function elements, said program control means including a plurality of control programs which are distinguished from one another as to switching sequence and/or switching times, whereby different spinning machine operating conditions can be accommodated by said servicing means, and program switch control means for switching said program control means from one control program to another.
Claim 3
Dependent Claim
37 words

Claim 4
Dependent Claim
32 words
Servicing apparatus according to claim 2, wherein said program switch control means includes a selector switch at the servicing means for setting a program appropriate to the spinning machine to be serviced.
Claim 5
Dependent Claim
31 words
Servicing apparatus according to claim 3, wherein each spinning machine is provided with a switching element that sets the selector switch in accordance with the operating condition of the spinning machine.
Claim 6
Dependent Claim
36 words
