ABSTRACT:
Method for the movement by friction of a set of two bands of superimposed flexible material, using at least two feed rollers that turn in the direction of band movement so that they are all pulled in unison, occasionally involuntary offsetting can occur in the mutual correct position of the bands, the method includes the placing of antifriction devices between both adjacent bands that allow mutual movement between both bands when they are pressurised between the opposite rollers and are pulled by them, without slipping between the bands and rollers, and because on at least one operative cycle the method includes an adjustment stage wherein the two rollers have a tangentially different speed so that one of the bands is pulled to a greater distance than the other, in order to correct the aforesaid involuntary offsetting in the mutual position between both bands.
