Abstract
A profiled guide rail, for use in providing a guide path for a roller chain in a web-fed rotary printing press, utilizes a plurality of slits as paths through which ink particles and paper dust can pass out of the track in the guide rail along which the roller chain travels. These slits pass through at least one leg of the guide rail and are longitudinally spaced in the direction of travel of the roller chain.

A profiled guide rail usable to receive and guide a roller chain movable in said profiled guide rail for the feeding of paper in a web fed rotary printing press, said profiled guide rail comprising:
- a base body;
- first and second spaced legs extending at right angles from said base body, said first and second spaced legs and said base body defining a generally C-shaped conduit for a roller chain;
- and
- a plurality of openings in at least one of said first and second legs, said plurality of openings each penetrating through an entire width of said at least one of said first and second legs and extending at right angles from said base body and being spaced from each other in a running direction of a roller chain receivable in said profiled guide rail.
A profiled guide rail usable to receive and guide a roller chain movable in said profiled guide rail for the feeding of paper in a web fed rotary printing press, said profiled guide rail comprising:
- a base body;
- first and second spaced legs extending at right angles from said base body, said first and second spaced legs and said base body defining a generally C-shaped conduit for a roller chain, each of said first and second legs having a groove, said grooves defining a track having a width for receiving a roller chain;
- and
- a plurality of openings in at least one of said first and second legs, said plurality of openings penetrating through said at least one leg and spaced from each other in a running direction of a roller chain receivable in said profiled guide rail, each of said openings having said width of said track.
A profiled guide rail usable to receive and to guide a roller chain which is movable in said profiled guide rail to feed a paper web in a web fed rotary printing press, said profiled guide rail comprising:
- a generally rectangular base body;
- first and second spaced legs secured at inner ends to said base body and extending from said base body generally perpendicular to said base body and parallel to each other, said base body and said first and second spaced legs defining a generally C-shaped conduit for receiving a roller chain;
- a groove formed on an inner surface of each of said first and second legs, said first and second grooves facing each other and forming guide tracks for a roller chain, each of said guide tracks having a width;
- and
- a plurality of openings in at least one of said first and second legs, each of said openings penetrating through said at least one leg, each of said openings having a length at least as great as said track width.
