Eccentrically mounted gear 1 rotates about fixed axis A and meshes with gear 5. Gear 7 is rigidly attached to gear 5 and rotates together with it about axis B. Link 6 is connected by turning pairs C and B to gear 1 and to link 8 which turns about fixed axis D. Gear 7 meshes with gear 9 which rotates about axis D. Through gears 10, gear 9 drives rolls 2 which are rigidly attached to gears 10. When gear 1 rotates at uniform velocity, rolls 2 have an intermittent reversing rotary motion that feeds the fibrous material between rolls 2 and pressure rollers 3.
