  • Patent number: 6022452
    Abstract: An apparatus for cutting a tail in a web sheet traveling through a nip between the queen roll and king roll of a calender includes a waterjet positioned adjacent the edge of the web upstream from the nip for directing a jet of water towards the web and the queen roll. The waterjet cuts a tip or leader and creates a tail that continues to travel with the remainder of the web sheet towards and through the nip. The waterjet penetrates the web and splashes against the queen roll such that the wetted portion of the queen roll compresses against the leader of the tail to carry or pull the tail around the queen roll. A doctor blade is mounted in engagement with the queen roll in line with the tail to direct the tail away from the queen roll and towards the next section of the papermaking machine. Guide trays positioned downstream of the doctor blade guide the tail to the next section of the papermaking machine. The doctor blade can be mounted stationary against the queen roll.

    Abstract: A clipped tail, which is the severed lead end of a paper web tail formed on a papermaking machine, is produced in the tail supported on a roll by combining the operation of a water jet, which projects a high pressure stream of water and is moved laterally to sever the tail transversely to its direction of travel, with the operation of a doctor having a blade, which moves with the water jet and which lifts and deflects the tail clip and following tail from the roll. An air stream is used to guide the tail downstream of the doctor blade. Both the water jet and doctors are mounted on a traversing apparatus to move transversely together across the traveling tail to automatically produce the tail clip and direct it to thread the downstream portion of the papermaking machine.

  • Patent number: 4931140
    Abstract: A method and a device for cutting an edge strip in a web by means of a water jet against a felt or wire of a paper machine for the threading of the web, whereby the end of the web is passed through the paper machine by means of the edge strip cut in the web, the edge strip being narrower than the web. In order to prevent the felt or wire from getting wet or being choked, the water jet is displaced back and forth across the direction of travel of the web so that the water jet cuts a gently wavelike edge in the edge strip. Correspondingly, the water used in the cutting and the filling agent or other such waste possibly separated from the web spread over the web over a wider area instead of spreading linearly, whereby the felt or wire will not get wet or choked.

  • Patent number: 4560438
    Abstract: A method and apparatus which reduces the amount of energy consumed in drying a paper web are disclosed. The reduction is accomplished by trimming the paper web while it is being conveyed on a moving fabric to divide the formed web into a trimmed web and couch trimmings respectively. Thereafter, suction is applied in the area where the pick-up of the trimmed web from the fabric is accomplished so as to deflect the portion of the felt on which the couch trimmings lie. As a result, only the trimmed web is conveyed to the drying section so that no energy is expended in drying the couch trimmings. The apparatus and method is particularly applicable to the manufacture of paper having a low grammage (basis weight) since contact between the couch trimmings and the pick-up felt is avoided.
