Abstract
A method for the separation of the paper web from the forming fabric in a paper-making machine comprising dividing the web into lengthwise strips to lessen the web adherence to the wire by utilization of a spray means incorporating a plurality of nozzles and then effecting web knock-down and separation from the wire by use of a slotted spray through which pressurized air jets are directed. Through this method very low pressures are required to achieve web separation and the risks of re-contact between web and wire are positively prevented.
