This invention relates to a spool for wire
stranding machines, and it aims to provide va
means which will -simplify and expedite the spool

A further object is to provide a novel construc
tion wherein the spool is made in interlitting sep
arable sections having adjustable means to po
sition the spool of wire and which also functions
to hold the sections together and against separa
tion, and further to provide in connection with
the drum. This band is fastened at 25 to the
frame I5 at one terminal, while the other termi
nal is free. Anchored to a stud 26 in the ñxed
terminal of the brake band is a contractile coil
spring 21 carried by a screw member 28 passing
through a bifurcation or slot 29 in the free ter
minal of the brake band and above which a nut
30 is screwed onto the bolt 28 for adjustment

The more specific objects and advantages will
