 vom Bunddurchmesser sondern sie ist bei leerem Haspel am grössten. Da die speisende Stromquelle aber wegen der für   grossen Zug vorgesehenen Getriebestufe   ohnedies für noch grössere Motordrehzahlen bei vollernFeldunddaherentsprechendgrössereSpannungenbemessenseinmuss, istindieserHinsichtkeinMehraufwand erforderlich. 



   Die Regelungsart mit konstanter Motorerregung auch für den Bereich grosser Züge zu verwenden, wäre nicht zweckmässig, weil dies eine Stromquelle erfordern   würde,   die im   Bunddurchmesserverhältnis   mehr Spannung liefert, als dies bei Regelung im Motorfeld notwendig ist.

 on the coil diameter but it is greatest when the reel is empty. However, since the supplying power source has to be dimensioned for even higher engine speeds with a full field and therefore correspondingly higher voltages due to the gear stage intended for large traction, no additional effort is required in this regard.



   Using the control mode with constant motor excitation also for the area of large trains would not be advisable because this would require a power source that supplies more voltage in the collar diameter ratio than is necessary for control in the motor field.

PATENTANSPRUCH : Haspelantrieb für Bandwalzwerke od. ähnl. Einrichtungen mit einem mindestens zweistufigen Wechselgetriebe zwischen Haspelmotor und Haspeltrommel, dadurch gekennzeichnet, dass die beiderGetriebestufe für grosse Bandzüge verwendete, an sich bekannte Regelungsart mit konstantem Strom und bandge- schwindigkeitsproportionaler ELK des Haspelmotors zugleich mit dem Einschalten der Getriebestufe für kleine Bandzüge auf eine Regelung mit konstantem Motorfeld und mit zugleichmit dem Bunddurchmesser steigendem Strom umgeschaltet wird. PATENT CLAIM: Reel drive for strip rolling mills or similar Devices with an at least two-stage change gear between the reel motor and the reel drum, characterized in that the two gear stage used for large belt pulls, known per se control type with constant current and belt speed proportional ELK of the reel motor at the same time with switching on the gear stage for small belt pulls to a control with constant Motor field and with the current increasing with the collar diameter.
