When the fore end of
the material reaches a position somewhat for

downwards from the feed belt and the pressing
member 24 will be moved downwards toward the
beater 22, while the die 26' is moving toward the
blade, with hemp material resting on it. After
an interval of time, the pressing member 24, the
' beater 22, the blade 26 and the die 26’ are brought
in their respective operative positions, and the
rear part of hemp material will be opened by the
tween the endless bands 31 and 28, and as soon
as the cross bars are moved off the said endless
bands, the treated material will hang down and
be received on the pole 48. Thereupon com

the commencement of the reverse movement of 10
material, on the right side the pressing member
24' will be moved upwards and the die 26’ will be
moved downwards, and accordingly no work will
be effected on the right-hand equipment. Thus,
the regular operation of the machine is repeated 15
by means of cams, levers and toothed wheels
which are arranged in timed relation in a suitable
beater 22. When the fore end of the hemp ma—
terial reaches a position near the fore blade 21
and the die 2'l' on passing through between the
endless bands 28 and 33, the endless band 38 and
the die 21’ are moving downwards and the press
when a material is supplied in position on a sup
ing member 25 is moving upwards, so as not to
interfere with the forward movement of mate
rial. In due time, said endless band, die and
pressing member will stop, and the fore end of
material will advance to a point somewhat for
ward of the center of the beater 23. At that time,
the endless band 38 and the die 21' will be moved
upwards and the pressing member 25 will be
moved downwards, and when said band 38 is
brought in contact with the endless band 31, ma
terial will be moved in a reverse direction as will
be evident from the fact that belts 28 and 31
being in contact with each other will cause the
lower portions of the belts in contact with the
material to move in reverse directions with re
spect to each other. In the meantime, the fore
end of material will continue its forward move
ment, and the length of material between the
portion treated with the beater 22 and blade 26
and the untreated portion will reach a position
somewhat forward of the center of the beater 23,
and the pressing member 25, the blade 21 and die
21’ will not be brought in their working positions,
although material is moved in the reverse direc
tion, but after an interval of time they will be
brought in their working positions, and after said
length of material reaches a position somewhat
forward of the blade 21 and the die 21' the un
treated portion of material will be treated with
the fore beater 23 and blade 21. Thus, the
treated material is now carried in the reverse
direction on passing over the roller 39 of the end

provided between the chains 40 will come in a
position for receiving the treated material be
From the foregoing, it will be seen that the

dressing the material can be done economically
and continuously requiring only attendants for 25
supplying material on the supporting plate and
for dealing with the dressed material delivered,
without need of skill.
Having now particularly described and ascer
tained the nature of my said invention and in 30
what manner the same is to be performed, I
A hemp dressing machine comprising a mate
rial support, an endless feed band mounted near
said support, a guide roller mounted on an inter 35
mittently oscillatable arm for feeding said mate
rial and adapted to be moved into and out of en
gagement with said endless feed band, two spaced
beaters, movable pressing members to co-operate
with said beaters, cutting blades and movable 40
dies co-operating therewith for scutching the
material passing the beaters, endless intermediate
conveying bands arranged one above the other
in intermediate spaced relation between said two
beaters, endless chains arranged to travel be 45
tween said intermediary endless bands and in
contact therewith and provided with a number
of cross bars for carrying material from the ma
chine, and co-operating endless bands arranged
to- contact said upper and lower intermediate 50
endless bands respectively, one of said last
named endless bands being movable in and out
of contact with a corresponding intermediary
endless band to intermittently feed the material
to the chain conveyer.
