Abstract
In a method and system for slitting thin strip magnetic steel such as transformer core material, a laser is mounted above the material and the material is wound from a pay-out reel to one or more take-up reels.
Claims24
A method of slitting a strip of amorphous metal or nano-grain steel (collectively, referred to herein as thin strip material), comprising,
- winding the thin strip material from a pay-out reel to one or more take-up reels and slitting the thin strip material using a laser as it is wound from the pay-out reel to the one or more take-up reels.
A method of 8, wherein the plate is a bevel plate.
A laser slitter for slitting strip material, comprising
- a payout shaft for receiving a pay-out reel, and at least one take-up shaft for receiving at least one take-up reel or mandrel, the pay-out and take-up shafts defining an upstream and a downstream side, respectively, for strip material wound between the upstream side and the downstream side, and
- at least one laser operably mounted between the upstream side and the downstream side.
