Background:
The transmission ratio is going to be changed, this creates a new transmission with a defined starting point.Therefore, it is possible to position a starting bar and to use coarse and fine VARIO bars similar to PB-System.

Starting bar:
By using the starting bar the fiber goes softer into the comb. The target is combining the advantages of the ERA machine and the PB combing system.

Modification:
The transmission ratio of the main shaft and the shaft for the VARIO COMB has to be changed from 1:2,86 to 1:2

For this modification the replacement of a gear is necessary.
