d, d are ruler bars, to support the copper rollers over which the wire revolves.
K is the breast roller, round which the endless wire turns.
N is the point where the shaking motion is given to the machine.
M is the guide roller, having its pivots movable laterally to adjust the wire and keep it parallel.
L is the pulp roller, or “dandy,” to press out water, and to set the paper. r, is the place of the second, when it is used.
H is the first or wet press, or couching rollers; the wire leaves the paper here, which latter is couched upon the endless felt p; and the endless wire o returns, passing round the lower couch roller. By Mr. Donkin’s happy invention of placing these rollers obliquely, the water runs freely away, which it did not do when their axes were in a vertical line.
e, e are the deckles, which form the edges of the sheet of paper, and prevent the pulp passing away laterally. They regulate the width of the endless sheet.
f, f are the revolving deckle straps.
R is the deckle guide, or driving-pulley.
g, g are tube rollers, over which the wire passes, which do not partake of the shaking motion; and,
