by means of special construction, and‘ special
mounting. No independent securing means are
required, but an element 80 of rubber or the like
10 is received by a recessed portion 8| of element
82, and a portion of said element 80 passes be
tween the member 82 and the adjacent moisten

A channel element or the

15 container, and is itself secured at 84. Freedom
' of movement and the continuous unobstructed
feed of the moisture is provided and no care
- whatever is required, the moistening device func
‘tioning automatically, and the ducts 18 having
20 a continuous supply through pipe 86. Moreover,
element 80 prevents the ?ow of more water than
moving beyond a predetermined path, at this
stage of the travel of the spindles. It also ap
pears from Figure 12 that the series of plates
I08, I08’, etc., is mounted by means of vertical
angle bars such as III. The-strips I04 extending
along the plates, such as elements I00 and IM of
Figure 12, pass into the end portions of tubular
elements 98, 98', and are outwardly de?ected as
shown at I08’, whereby the associated elements
are resiliently held or retained,_in an obvious
manner.

The plates of series I08 by reason of their close
proximity to the path of the spindles contact the
cotton wound about the spindles and prevent its
rotating as the spindles are rotated reversely.

A slight modi?cation of this construction is
illustrated in Figure 10, wherein the ?brous con

a pipe such as 88, whereby moisture is supplied
to the individual ?brous containers, and the
quantity of moisture is regulated by the afore
said valves.

The series of plates provides similar
means for holding the cotton carried on each in
dividual row of spindles.
On the stripping side of the machine, the spin
