The present invention has for its purpose to
The present invention relates to an improved
machine for impressing strengthening ribs or
beads in the cylindrical surfaces of can bodies
and the like. Such strengthening beads are con
overcome all of the di?iculties encountered with
machines of the prior art.

.
A primary object of the invention is to pro
vide a machine capable of forming in the side
walls of can bodies, reinforcing ribs, grooves or
beads of greater depth and uniformity than has

denting or collapse thereof and to make possible
the use of lighter sheet metal stock than would

manufacture of can bodies, attempts have been 10 venting slippage between the inner and outer
beading rolls of can beading ‘machines, or, in
other words, between the can supporting man
drels, the can bodies and the beading rolls.
Another object. is to provide‘ means which will

mum depth, thereby to compensate for the
strength and stiffness ordinarily imparted to th
bodies by heavier stock.

the invention will be apparent to persons skilled
in the art, from a consideration of the speci?c
