US Patent:

6563078, May 13, 2003

Filed:

Oct 25, 2000

Appl. No.:

09/697003

Inventors:

Patrick J. Momany - Bainbridge Island WA

Assignee:

Edgewise Tools, Inc. - Bainbridge Island WA

International Classification:

B23K 2614

US Classification:

21912167, 21912183, 21912182, 21912173

Abstract:

A gore cutter with a principal roller and a pinch roller, a material feed roller and a take up roller. The take up roller has a tension bar transducer for controlling the rate of take up and feed of a material to be cut over the roller. A movable laser cutting assembly is controlled to move along a path parallel to a central axis of the principal roller.

International Classification:

B23K026/08
B23K026/38

US Classification:

219/121670, 219/121820

Abstract:

A gore cutter has a principal roller and at least one pinch roller. Material is fed over a feed roller and a take up roller, and the take up roller employs a tension bar transducer for controlling the rate of take up and feed of a material to be cut over the roller. Movable laser cutting assembly is controlled to move along a path parallel to a central axis of the principal roller.

International Classification:

US Classification:

21912167

Abstract:

A laser beam generator is mounted stationarily relative to a sheet roll feed mechanism of the type used in roll feed drafting plotters so as to project a laser beam lengthwise of the crossrail of such feed mechanism. A right angle reflecting and focusing assembly is mounted on a carriage moveable along the crossrail for directing the laser beam toward a sheet positioned by the feeder. The sheet is moved in one axis (the x-axis) by the roll feed mechanism, while the reflecting and focusing assembly is moved in the other axis (y-axis) by the carriage--all under computer control. On-off signals for the laser are derived from the pen up, pen down signaling mechanism of the plotter so that a design or pattern is cut in the sheet as though the plotter were drawing a drafting pattern. Mechanism is provided to calculate the actual speed of the focused laser beam relative to the sheet being cut and to adjust the power output of the laser automatically so that a uniform cut is achieved. Inert gas under pressure is supplied to the area of the cut in synchronism with actuation of the laser.
