shake
A device on the wire of the Fourdrinier
papermaking machine which causes the wire to
oscillate in a plane at right angles to the
forward movement of the wire. Its purpose is
largely like that of the vatman's shake of the
mold in hand papermaking, which assists in
securing the desired intermingling of fibers of
the sheet. The oscillations may be varied in
frequency and length of stroke to obtain the
required results. (17 , 60 )
