ABSTRACT:
A moving web expanding and guiding apparatus comprises, in combination, an expander device having three screw rolls arranged side by side, and a guide device having a required number of centering rolls, wherein the intermediate screw roll is movable in a direction at right angles to the web surface and the centering rolls are tiltable in the direction which corrects the deviation of the web.
The apparatus is provided with a screw roll emergency stop mechanism for quickly stopping the rotation of the screw rolls when the moving web excessively zigzag deviates, and a centering roll time delay stop mechanism for stopping the operation of a centering roll tilting mechanism when the centering rolls have returned to their neutral position.
