Fellows discloses a first embodiment (see Fig. 1) in
which a stretchable seamless printing sleeve 17 is fitted onto
a tube 10 having a larger external diameter than the internal
diameter of the sleeve. The tube 17 has a passageway 16 and a
series of spaced apart circumferential grooves 10b on its
outer surface. The passageway 16 and each of grooves 10b is
connected to the inside of the tube 10 which, in turn, may be
connected to a source of compressed air. Fellows teaches that
the printing roll is assembled by sliding the sleeve axially
over the seal 13 to the conical part 10a of the tube, at which
point the space 13a between seal 13, the end of the sleeve 17
and the end of the tube 10 becomes pressurized. As the sleeve
passes over the tube, the interior of the sleeve is internally
pressurized by compressed air distributed from inside the tube
