Abstract
A process for performing a laser treatment on discrete sheets of material. The present invention provides for shingling discrete sheets of material and for tracking and contacting a laser beam on the continuously moving shingled sheets.
Claims12
A process for laser treating material, said process comprising the steps of:
- shingling discrete sheets of said material onto a conveyor, such that each of said discrete sheets of material overlaps a portion of an adjacent one of said discrete sheets of material;
- conveying each of said discrete sheets in a pre-determined path, in a continuously moving fashion, said path in the view of a laser system;
- and
- directing a laser beam from said laser system onto said discrete sheets, one sheet at a time, in succession.

A system for laser treating discrete sheets of material, comprising:
- a shingle transfer for shingling said discrete sheets such that each of said discrete sheets of material overlaps a portion of an adjacent one of said discrete sheets of material;
- a conveyor for transporting said shingled discrete sheets in a predetermined path;
- a laser positioned in relation to said conveyor to treat said shingled discrete sheets, wherein the focal length of said laser is at least relatively 10% shorter when compared to a focal length of a laser used on a continuous sheet web system when both are processing at the same rate of material throughput and when both have the same laser treatment time requirements.
A process for laser treating material, said process comprising the steps of:
- shingling discrete sheets of said material onto a conveyor, such that each of said discrete sheets of material overlaps a portion of an adjacent one of said discrete sheets of material;
- conveying each of said discrete sheets in a pre-determined path, in a continuously moving fashion, said path in the view of a laser system;
- directing a user beam from said laser system onto said discrete sheets, one sheet at a time, in succession;
- providing a stack of pre-cut discrete sheets of material adjacent said conveyor;
- and
- providing a discrete sheet leading edge detector for triggering said laser system.
