Deckel-straps of india-rubber are
fastened on both sides of the wire screen, and move with it, thus
holding the watery pulp in place. The deckel-straps are adjustable and
fix or regulate the width of the paper. These and the gate, or "slicer,"
are attached to what is termed the deckel-frame, which corresponds to
the deckel used by paper-makers in the days when the manufacture was
carried on by hand. As the stream flows onto the endless belt of wire
cloth, the water which has borne the fibers filters into the trough
beneath. Being charged with very fine fibers, size, coloring matter, and
other similar ingredients, it is carried back into the pulp-chest to
save these materials, as well as to contribute again to the extra supply
of water needed. For this reason the trough into which it falls from the
revolving "wire" is called the "save-all." A shaking motion is imparted
to the "wire" from the frame upon which rest the rolls that keep it in
its never-ending round. This aids in draining away the water and mats or
interlaces the fibers together.
