This invention relates to thread spools or bob
bins such as used in connection with‘the shuttles
of sewing machines or devices of this type and
kind supporting threads, lines, cords and the
like. More particularly, the invention relates to
the method of treating wound devices of this
kind to maintain the strands of the spool llike
body against displacement or against accidental
or undesirable unwinding, while at the same time,
adding lubricating properties to the strand. The
novel features of the invention will be best under
stood from the following description when taken
together with the accompanying drawing in
which certain embodiments of the invention are
disclosed and in which the separate parts -are
designated by suitable reference characters in
each of the views, and in which:

For purposes of this description, the vat sta

`Arranged on each head 3l and at opposite
sides of the spindles 3o is a pair of ejector pins
37. On these pins are arranged springs 3d which
normally support the pins in raised position,
and stop pins 39 are employed to limit upward
movement of the pins 31. . The heads [email protected] of the
pins 3l are normally disposed adjacent the lower A

able unwinding which takes place with ordinary
threads when used on high speed sewing ma
chines. Further the application of the wax or
parafïln coating also gives to the thread or
. strand a lubricating property which is desirable
in the use thereof.
In some instances and in processing strands
of this type and kind various other materials or
compounds may be used other than wax or par
añln as herein speciñcally deiined.
From this
standpoint it will be understood that 'the method t:
herein deiined consists primarily in the complete
submersion of a wound strand body in a suitable
fluid, then in rotating the thread strand body at
high speed to throw off all surplus of the mate
rial and then to fix the fluid material upon the
strands in producing lthe resulting product,
It will be apparent that the strand body pro
duced according to the method herein defined
may be wound in any desired manner and many
oi these bodies' have cross windings as int-,he bob
bin illustrated. This type of winding maintains
the strands against collapse or, displacement.
With the present method of coating or impreg
nating the strands with the material which es
tablishes _a slight adhesion between contacting
portions of across _wound strand, the body is
further maintained in its wound condition in the
