This invention relates to reeling devices, and,
more particularly, to reeling devices adapted for
association with hot rod mills and the like.
In the metallurgical industry, in the manu
5 facture of attenuated metal stock, and, especially,
rods and other elongated cylindricalobjects, it
is'customary to introduce billets of metal, which
have been heated to the proper temperature, to
rollin-g mills for the purpose of elongating them
10 and reducing the diameters thereof. In the case
‹ of rod mills, when a billet is reduced through a
series of stands of rolls, the rod, as it emerges
from the last pair of rollsI 'is of considerable
length and travels at conslderable speed, x-and it
15 is necessary to provide some reelingëmean's to
coli the same.
To this end, driven reels are positioned some
distance from the last pair of rolls in the roll
train invline with the axis of the passes thereof
20 to which the biliet is introduced. Such reels are
. 'customarily synchronized in speed with the last
pair of rolls so as to exert upon the hot _stock
no pulling tension, except as is hereinafter
more, are caused by the pull of the reel to_be
come tightly' wound about the upper extremities .
of the inner circle of pins thereof. Since the
circle defined by the upper limits of the pins is
usually of less dlameter than that defined by
their base portions to facilitate strippingthe coil,
the rod that is .wound about the top Åportions
thereof is coiled to a dlameter smaller than the
convolutions comprising the main body of the
coil. When such a coil is stripped, these termi
nal portions of the rod, coiled to a smaller di
ameter, fall to the inside of the coil. and become
tangled with the other convolutions thereof,
which necessitates that they be removed as scrap.A
It has also been proposed to make a reel on
the revoluble base of which coil-forming pins are
?xedly mounted to lean out'wardly, so that any
wire coiled about the upper extremities of' such
pins will form convolutions having a dlameter
equal to, or greater than. the mean dlameter of
the coil of which it is a part. The extremities
of the fixed coil-forming pins, however they may
be disposed to form uniform convolutions of wire,
collectively occupy an area commensurate with
stated. Such reels usually_`comprise a revoluble ~'in fact, greater than-that of such convolutions,

unusable, is preserved and handled so as to re

the inward recession of the arms 6, during the
discharging operation, provides that the coil be
cleanly released, precluding disfigurement of the
stock, and insuring against binding, tangling, and
other complications, in stripping.
The apertures l in the base member I, within
which the arms 6 are adapted to oscillate, are 10
intentionally made of considerable size so that any
dirt or other foreign matter, which may collect
upon the base member I during the operation of
the reel, can be cleaned-out to insure free move
