An apparatus for slitting a sheet material web as it is wound onto a roll including at least one winding drum supporting the web, a moveably reel spool positioned in a parallel and spaced apart relationship with the winding drum, a slitting device and a control system. The slitting device includes a track member and a slitting member moveably mounted on the track member. The slitting member continuously slits the sheet material web longitudinally along its length as it is wound onto the roll. The control system controls the position of the slitting member on the track so as to maintain a predetermined penetration of the slitting member within the roll as the roll increases in size. A method for continuously slitting the roll includes carrying the sheet material web over a winding drum, depositing the sheet material web onto a rotating reel spool to form a roll of sheet material web, moving the slitting member so as to continuously slit the sheet material web on the roll and controlling the movement of the slitting member with a control system so as to maintain a predetermined depth of penetration of the slitting member within the roll.

Method and apparatus for slitting a sheet material web

An air press for noncompressively dewatering a wet web to consistency levels not previously thought possible at industrially useful speeds without thermal dewatering.

Air press for dewatering a wet web

An apparatus for penetrating a sheet material web being carried on a fabric. The apparatus including a penetrating device and an air flow that separates a portion of the sheet material web from the fabric adjacent the penetrating device so as to bring the web into contact with the penetrating device. In one embodiment, a vacuum lifts a portion of the sheet material web into contact with a slitting member such that it continuously slits the sheet material web longitudinally along its length as the fabric carries the sheet material web beneath it. In an alternative embodiment, a pressurized air stream is directed to a bottom portion of the sheet material web so as to separate the web from the fabric. A method for penetrating a sheet material web as it is carried on a fabric includes the steps of carrying the sheet material web on a fabric in a longitudinal direction, applying an air flow to the web so as to separate a portion of the web from the fabric, penetrating the web as it is separated from the fabric and reapplying the sheet material web to the fabric.

Air press for dewatering a wet web with pivotable arm seal

An air press for noncompressively dewatering a wet web to consistency levels not previously thought possible at industrially useful speeds without thermal dewatering. Side seal members are positioned beyond the lateral edges of the wet web and support fabrics. These seals flex into sealing contact with the opposite sealing contact surfaces upon exposure to the presurized fluid of the air press.
