Patent number: 5033201Abstract: A tool for use in setting the height of a cutting blade mounted in a rotary cutting cylinder includes an anvil that is mounted to the rotary cutting cylinder by a lost motion connection assembly. The lost motion connection assembly permits the mounted anvil to move radially relative to the cylinder, while preventing tangential and rotative movement of the anvil relative to the cylinder. The tool includes a pair of dowel pins that are inserted in radial holes provided in the cylinder to mount the anvil to the cylinder. The lost motion connection assembly connects the dowel pins to the anvil in a manner that permits the radial movement of the anvil relative to the pins and the cylinder. The anvil mounted on the cylinder is moved radially toward the cutting blade of the cylinder until it rests on top of the cutting edge of the blade, and is then tapped lightly to drive the cutting blade downward into the blade slot formed in the cylinder.Type: GrantFiled: April 20, 1990Date of Patent: July 23, 1991Assignee: Roto-Die Company, Inc.Inventors: Doyle Hinkle, Stephen T.
