The drive for the intaglio printing roller 12 in
cludes a worm 25 ?xed on an extended end of the
mandrel ii. and located on the outer side of one
of the wall plates II. This worm 25 is in mesh
witha worm pinion 26. on a drive shaft 27 rota- .5
tively supported in bearings 28 on the side of one
wall plate. This drive shaft 2'! is provided with a
pulley 29 associated with a drive belt 38 adapted
to engage with a prime mover,.such as an electric
motor.‘ Rotations from the drive shaft 21 are 55

arms I 5a which are pivotally supported at one of
their ends on a spindle |5b which is rotative
through the wall plates II. This spindle has a
10 projecting end which is provided with a handle 32
by which the frame may be lifted when desired.

adjustable weight 6| which controls the pressure
of the doctor blade engaging against the intaglio

other strip of material 63 is illustrated provided
with an embossed design 64. This strip of ma
