Abstract
A papermaking machine uses a low pressure water jet mounted on a pneumatic actuator for movement at least as fast in the cross machine direction as the paper web moves in the machine direction for a distance of 2 to 12 inches. The jet rapidly cuts a tail with a blunt edge of 2 to 12 inches wide from the web. The actuator is mounted on a screw or belt driven carriage to traverse the web and expand the tail after it has been threaded through the dryer section until the tail encompass the entire web and thus completes the threading process. A controller coordinates an air jet positioned beneath a doctor blade and a vacuum suction roll which engages the last press roll. The air jet and vacuum suction roll are actuated when the blunt end of the tail engages the doctor blade. In this way a tail with little or no streamer is formed and blown onto a dryer fabric supported on a vacuum suction roll which leads the tail into a single tier dryer section.
