This invention relates to improvements in load
fluid system for operating the coil loading and
ing, and feeding apparatus for coils of strip metal.
' feeding means of my invention.
‘ Heretofore coils of strip metal have been loaded
In the drawings, an expansible mandrel, I0 is
onto rotatableyexpansible coil supporting blocks
shown as being rotatably mounted on a base frame \
or mandrels by power, by mounting'the coil on a
movable carriage and elevating the coil so its open
center can be moved onto the ‘mandrel. The
mandrel is then expanded after the coil has been
fully mounted thereon. ,As the coil is loaded onto
I2 at the entering end of a pair of pinch rolls I I,
I I. Said mandrelserves to support a coil of strip
metal I5 for unwinding, and said pinch rolls‘serve
,to grip and unwind the strip metal and feed it
the mandrel, its tail end, which projects out
1.0 to a suitable processing device such as a ?ying
wardly from the ‘coil, is moved sideways with the
coil between a pair of pinch rolls. These pinch
rolls are adapted to grip said tail end‘ of the coil
and feed it to a cropping shear, or a processing
apparatus such as a roll stand, slitter, brushing
in
shear. I3, which is adapted to crop the ends there;
of, before the metal passes to a pickling and
cleaning device or other processingv apparatus
(not shown). Said flying shear is shown in the ,
unit, pickling and cleaning unit, or any other type ‘
of processing apparatus, The pinch rolls fre
quently grip the metal ‘and. unwind the coil before
drawings for illustrative purposes only-andris no,
part of my present invention so will not herein
be shown Or described in detail.
The base frame I2 is mounted on a suitable
foundation and includes a pair of parallel spaced
it is fully expanded. This causes the coil to spring
and unwindto such an extent that the mandrel 20 connected I-beams I6,‘ I6 extending parallel to
the axis of the mandrel I0. Said mandrel is suit
cannot be su?iciently expanded to fully grip the
a-bly mounted on said base frame in a mandrel
inside of the coil, resulting in further springing
housing I‘! and extends along said frame between
and unwinding of the coil and making it, neces

sary to remove and rewindthe coil before process

Among the objects. of my invention are to pro- ,

feeding means for coiled strip metal wherein the
coil of strip metal I5, carried on a coil supporting
