Abstract
Abstract In a printing machine, an arrangement for adjusting web register includes a frame detachably mounted on the machine, and a pair of guide rollers over which a web is guided. A downstream roller is raised and lowered, and both rollers, as well as a pair of frame members, are turned as a unitary assembly relative to the machine.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
160 words
An arrangement for adjusting web register in a printing machine, comprising: (a) a frame detachably mounted on the machine, said frame having a pair of frame members extending in mutual parallelism along a longitudinal direction, and spaced apart along a transverse direction generally perpendicular to the longitudinal direction; (b) a pair of guide rollers over which a web is sequentially guided along a path to a printing station, said guide rollers extending along the transverse direction between the frame members and being spaced apart along the longitudinal direction, said guide rollers being journaled for rotation about respective axes lying in a common plane; (c) elevation means for raising and lowering a dowstream one of the guide rollers for movement in an elevation direction generally perpendicular to both the transverse and longitudinal directions; and (d) means for turning the guide rollers and the frame members as a unitary assembly relative to the machine in a curved course in said common plane.
Claim 2
Dependent Claim
160 words
An arrangement for adjusting web register in a printing machine, comprising: (a) a frame detachably mounted on the machine, said frame having a pair of frame members extending in mutual parallelism along a longitudinal direction, and spaced apart along a transverse direction generally perpendicular to the longitudinal direction; (b) a pair of guide rollers over which a web is sequentially guided along a path to a printing station, said guide rollers extending along the transverse direction between the frame members and being spaced apart along the longitudinal direction, said guide rollers being journaled for rotation about respective axes lying in a common plane; (c) elevation means for raising and lowering a dowstream one of the guide rollers for movement in an elevation direction generally perpendicular to both the transverse and longitudinal directions; and (d) means for turning the guide rollers and the frame members as a unitary assembly relative to the machine in a curved course in said common plane.
Claim 3
Dependent Claim
28 words
The arrangement according to claim 1, wherein the frame includes cross members spaced apart along the longitudinal direction, and extending along the transverse direction to the frame members.
Claim 4
Dependent Claim
95 words
The arrangement according to claim 1, wherein said one downstream roller has one end journaled in a bearing block having a pair of passages extending therethrough along the elevation direction; and wherein the elevation means includes a guide column extending through one of the passages and having opposite column ends secured to one of the frame members; a screw in driving engagement with, and extending through, the other of the passages; and a drive motor in force-transmitting relationship with the drive screw to adjust the elevation of the bearing block and said one downstream roller.
Claim 5
Dependent Claim
65 words
The arrangement according to claim 1, wherein each roller has opposite ends operatively connected to respective frame plates mounted on respective frame members, and wherein the turning means includes machine plates mounted on the machine, each machine plate being generally co-planar with a respective frame plate and bounding a curved passageway therewith; and wherein the turning means further includes ball bearings in each curved passageway.
Claim 6
Dependent Claim
39 words
The arrangement according to claim 4, wherein the turning means further includes a drive motor in force-transmitting engagement with a drive screw along which a carriage is mounted, and a linkage operatively connected between the frame and the carriage.
