Abstract
A process for precision patterning or cutting of a sheet stock, such as an adhesive tape, includes the step of irradiating a surface of a sheet stock with an irradiation source to pattern or cut a part in the sheet stock and adjusting at least one of a beam width and the power of the irradiation source to form a cut in the sheet stock to a controlled depth. The method is particularly useful for precision cutting adhesive members, such as adhesive fluid seals, for an inkjet print cartridge.
Claims37
A process for precision patterning sheet stock, comprising:
- initially irradiating a surface of a sheet stock with a beam from an irradiation source to pattern a part in the sheet stock at a linear rate;
- and
- cutting at least one cut having a controlled depth in the sheet stock with the beam, wherein at least one of a beam width and a power of the irradiation source is adjusted so that a cutting rate is non-linear as th e controlled depth is approached.
A system for precision patterning sheet stock, comprising:
- an irradiation source that initially irradiates a surface of a sheet stock with a beam to pattern a part in the sheet stock at a linear rate;
- and
- a controller that cuts at least one cut having a controlled depth in the sheet stock with the beam, wherein at least one of a beam width and a power of the irradiation source is adjusted so that a cutting rate is non-linear as the controlled depth is approached.
