formation lie, torn, the second drive must run smoothly, easily adjustable and yet strong enough to be able to To keep up with the speed of the machine. Besides that The device must not show any wear and tear during operation, which would interfere with the good puncture of the fascine and cause downtimes that are all the more detrimental to performance would than the manufacturing speed is greater.

The invention is based on the object of the requirements to be able to cope with the fastest machines and the disadvantages to eliminate the friction clutches.

The invention consists in that the friction clutches be replaced by an electric motor that provides a constant web tension that can be regulated as required guaranteed

In a first embodiment, an alternating current slip-ring motor is used, which is connected to a controllable autotransformer, which is allowed from ^xl and to -% and is set particularly as a function of the 2ug desired between the two drive stations.

In a second embodiment, a DC rotor motor is used used, its basic speed with the speed of other internal organs by means of an electronic amplifier is synchronized, which is controlled by two speed sensors, one of which is called "Geberdynaüio" from a mechanical control element of the said machine is driven, while the other, called the "receiver dynamo", coupled with the driven organ

In order to achieve a change in the Drelimonients and hence the web tension, it is sufficient to vary the position of a potentiometer which acts on the barker eleict tronic v _β
