2 Claims. (Cl. 101-225) This invention relates to a device for preover idlers 18 and through a second printing venting the slurring of the web as it passes couple. 1 g over the impression cylinder and into contact The web is held down against the surface of with the plate cylinder. This is the principal obthe impression cylinder positively at some dis- V 5 ject of the invention and it is carrie-d out in tance from the bite between the two cylinders 5 "z n plate cylinder 15.

a` form in whichthe web is diverted from a of the couple. This prevents vibration of the straight path to `the impression cylinder and web and any tendency for undulation of the caused `to wrap around the impressioncylinder same and insures that the web at the instant through a considerable arc before it comes into of printing shall pass through the couple l0 the bite between the printing vand impression smoothly and in firm contact with the impres- 10 cylinders. v l f sion cylinder.
