The fulling of cloth is effected by subjecting
cuts of cloth into a mill and put the ends together,
the cloth in roped or rolled form to alternate
pressure and release in the presence of heat and
moisture, customarily with the addition of soap
to lubricate the ?bers and facilitate the fulling
for an actual run of the mill of from 5 minutes
to 1/2 hour, and thus it takes as long or several
times as long to get the cloth in as is spent in
the useful operation of the mill. ’ In addition,
thereof. A standard method of effecting this
alternate pressure and release and the genera
tion of heat is through the use of opposed rolls
rotated to feed the cloth in rope form through
various ropes of cloth or to turn the pieces end

further time is lost through having to stop the
mill periodically to change the positions of the

valve III supplied through a pressure regulator
I I3 by pipe I I5 from a suitable source (not shown)
of fluid under pressure,
This valve III is operated by a control handle
actuated periodically by any suitable or preferred
timer means. Herein, the control handle effects
the movement of each piston in alternately op
posite directions upon movement of the control
handle back and forth throughout a small arc.
In this case, and in the form of Fig. 1 also, this
movement of the handle must occur at, alter
nately unequal intervals of time in order to
impart the differential extents of feed of the
cloth in opposite direction required to give the
the same surface speed, with capacity for lifting 15 constant output of fulled cloth by the mill. More
speci?cally, the timer is desired to move the
of the top roll a liberal distance away from its
control handle in one direction to cause the
companion bottom roll without interrputing the
reversal of travel of the cloth at the end of a
driving. The drive of the left-hand pair of
predetermined length of feed in the forward
opposed rolls rotates them concurrently to feed
the cloth from right to left and thus into crimp 20 direction, and then to move the control handle in
the opposite direction to again reverse the travel
box 19, while the corresponding concurrent rota
