Application No. 09/213,726
F.2d 760, 772, 218 USPQ 781, 789 (Fed. Cir. 1983), cert. denied, 465 U.S. 1026
(1984).
Claim 17, the only independent claim on appeal, reads as follows:
A device for varying the stroke amplitude of at least one axially oscillating
distributor roller in an application unit of a rotary printing press, wherein a
distributor roller is drivable by a distributor stroke drive via a distributor stroke
transmission including a coulisse having a groove and being adjustable from a
first position to a second position, and a sliding block movable in the groove,
comprising:
a first transmission member carrying the coulisse, and a second
transmission member carrying the sliding block, the distributor stroke
transmission being formed of said first and said second transmission members,
said coulisse being disposed adjustably relative to said first transmission
member, and both said first and said second transmission, members being
driven by the distributor stroke drive; and
an actuator for adjusting said coulisse, said actuator being carried by at
least one of said first and said second transmission members.
Hummel's invention relates to a mechanism for varying the axial travel of a
distributing roller or the like in a printing machine and, more particularly, is directed to a
mechanism which permits easy adjustment of the amount of axial travel of a distributing
roller while the press is operating. A printing press 10 embodying Hummel's invention
is shown in Figures 1-4. The press 10 comprises a frame 11 which includes a
side column or retaining plate 12 secured thereto by means of threaded bolts 14.
Distributing rollers 15a-d are carried by the frame 11 by means of bearings 16,
which permit both rotation and axial reciprocation of the distributing rollers.
