Abstract
A cutting station (10) that permits rapid change-over and adjustment of its cutting and anvil rollers (62,60) between printing runs is disclosed. The cutting station (10) includes a frame (14) having a longitudinal axis (19) defining a web travel path; an anvil roller (62) configured for rotatably mounting on the frame; a cutting roller (60) configured for rotatably mounting on the frame (14) adjacent the anvil roller (62); and an improved biasing assembly (18) for biasing the cutting roller (62) against the anvil roller (60). The biasing assembly (18) includes a track (80) extending transversely from the frame (14), a carriage (82) slidably mounted on the track (80) for movement toward and away from the frame (14), and a biasing member (84) mounted for vertical shifting movement below the carriage (82).
Claims20
A cutting station for a printing press, the cutting station comprising:
- a frame having a longitudinal axis defining a web travel path;
- an anvil roller configured for rotatably mounting on the frame;
- a cutting roller configured for rotatably mounting on the frame adjacent the anvil roller;
- and
- a biasing assembly including
- a biasing member for biasing the cutting roller against the anvil roller to effect cutting of the web, and
- mounting means for slidably mounting the biasing member to the frame for sliding movement along an axis generally transverse to the frame longitudinal axis.
A cutting station for a printing press, the cutting station comprising:
- an elongated frame having a longitudinal axis defining a web travel path;
- an anvil roller configured for rotatably mounting on the frame;
- a cutting roller configured for rotatably mounting on the frame adjacent the anvil roller;
- and
- a biasing assembly including
- an elongated track extending generally transversely from one side of the frame,
- a carriage assembly slidably mounted on the track for movement between a retracted position wherein the carriage is moved rearward away from the cutting roller and an operating position wherein the carriage is moved over the cutting roller,
- a biasing member,
- supporting means for shiftably supporting the biasing member to the carriage assembly for vertical movement toward and away from the cutting roller between a lowered position wherein the biasing member engages the cutting roller and biases it against the anvil roller and a raised position wherein the biasing member is moved away from and releases the anvil roller.
A printing press comprising:
- a printing unit having a frame defining a web travel path and means for printing a web of material as it passes along the web travel path;
- and
- a cutting station for cutting the web after it has been printed by the printing unit, the cutting station including
- an elongated frame having a longitudinal axis along the web travel path;
- an anvil roller configured for rotatably mounting on the frame;
- a cutting roller configured for rotatably mounting on the frame adjacent the anvil roller;
- and
- a biasing assembly including
- an elongated track extending generally transversely from one side of the frame, the track having a longitudinal axis generally perpendicular to the web travel path,
- a carriage assembly slidably mounted on the track for movement between a retracted position wherein the carriage is moved rearward away from the cutting roller and an operating position wherein the carriage is moved over the cutting roller,
- a biasing member,
- supporting means for shiftably supporting the biasing member to the carriage assembly for vertical movement toward and away from the cutting roller between a lowered position wherein the biasing member engages the cutting roller and biases it against the anvil roller and a raised position wherein the biasing member is moved away from and releases the anvil roller.
The printing press as set forth in claim 18, further including a three-position toggle switch coupled with said valve and having a raised position for raising the biasing member, a lowered position for lowering the biasing member, and an idle position for stopping the biasing member.
