Abstract
A method and apparatus for transferring vibrational forces to a wire of a papermaking machine for forming a web on the wire and for dampening vibrations imparted to the papermaking machine. In some embodiments, the apparatus is a vibrational device including a vibrational device frame, a vibration isolator coupled to the vibrational device frame to dampen vibration transmission to the papermaking machine, a vibration-inducing mechanism coupled to the vibrational device frame and operable to generate a vibration having a frequency and positioned laterally with respect to the vibration isolator in the cross-machine direction, and a vibrational head coupled to the vibration-inducing mechanism and directly contacting the wire to impart vibration to the wire.
