Abstract
A cover for a rotary die is centrifugally cast with multiple layers to substantially eliminate stress when the cover is cast in an arcuate shape for use in a die cutting system. A locking mechanism attached to ends of the cover is designed to be convenient to install on and remove from a cutting cylinder.
Claims19
In a die cutting system having a cutting blade and a cylinder opposing the blade so that a workpiece is cut between the cutting blade and the cylinder, the cylinder having a central axis, a radial direction relative to the central axis, and an axially oriented channel with first and second sides, an assembly comprising:
- a cover for receiving the cutting blade as the blade passes through a workpiece;
- and
- a locking mechanism connected to the cover for locking ends of the cover together when inserted in the axially oriented channel in the cylinder, the locking mechanism including a unitary first member having:
- a first sidewall for positioning against the first side of the channel,
- a second side wall for positioning against the second side wall of the channel,
- a bottom wall which, with the first and second side walls, forms a U-shape within the axial channel, and
- a tang extending upwardly from, and pivotable relative to, the bottom wall, the tang being between the first and second side walls to define with one of the first and second side walls a receiving channel.
