This invention relates to improvements in ap
paratus whereby sliver, for example, sliver of
'bast libres, such as jute, is wound into rolls and
the completed rolls are delivered one at a time
to a receiver.
The inclined track is carried by brackets I5
secured to the frame I6.
To guide the roll A in its travel on the inclined
track I3, so that the roll is prevented from tilting
or from assuming a position- oblique to the posi

there are disposed at opposite sides of the track

In one such construction in which the sliver is
wound between two end discs each unitary with
a half arbor, on completion of the roll, arms car
rying the end discs are swung apart, thereby with
