To drive oinor Spulo 1, dio is aufgosotzt on cino Laufaohso 2 serves oin drive wheel 3, which constantly rotates in dor gleichon Drohrichtung and with the same Drohgosohwindigkoit _Λ Dio Spulo in the shown Ausxiihrungsboispiol by Mitnehmorstifte 4 rigidly coupled with the wool Z IOIM winding The Wollo 2 is to be approached by the drive wheel 3, whereby the speed of the Wollo 2 has to decrease with an increase in G-rösso dos Wiekoldurchmossors in the Spulo, although the drive wheel 3 has a constant speed _{and is} due to the fact that the wheel 3 with © in © i? dio Wollo 2 umgobondon I ^ o 5 vorbundon is, with dor woitorhin the untoro part 6 oinor Roibungskupplung stands in fostor Vorbundon, the Roibungskupplung contains fornor oinon similar shaped o "boron part 7 and on them there is oino Schoibo 8 from oinom gocignoton fabric, boocignoton fabric Hard paper, Dor oboro toil 7 dor friction clutch is then with dor Wcllo 2 vorbundon, Dioso parts can not turn gogcnoinandor. If the coupling part 7 and 6 has been pushed on with enough pressure in andorgoprosst, the driving force from wheel 3 is transmitted via the sleeve 4 and the Coupling part 6 on.
