ABSTRACT:
The double-apron drawing mechanism includes a feed couple of rollers and a delivery couple of rollers, with the fibrous material being treated passing between the two endless aprons or belts of the feed couple, synchronously rotated about the driven and pressure rollers. One endless apron engages a stationary guide extending longitudinally of the travel of the fibrous material, while the other endless apron engages a movable guide arranged adjacent to the area of exit of the fibrous material from the feed couple toward the delivery couple.
The movable guide is mounted for infinite angular adjustment in vertical planes extending both transversely and longitudinally of the travel of the fibrous material, to provide for infinite adjustment of the gap between the endless aprons in the area of exit of the treated fibrous material from the feed couple.
