30. A method of processing denim material, comprising:
-
bringing the denim material into contact with a laser beam; and
controlling operating parameters of the laser beam including controlling at least power of the laser beam and moving speed of the laser beam, and also at least one of the parameters from the group consisting of frequency of the laser beam which controls a pulse duty cycle of the laser, wobble of the laser beam which controls an amount of spiraling of the laser beam, and pattern density of scribing carried out by the laser beam, to form a pattern which repeats in a cyclical arrangement which also has random parts. - View Dependent Claims (31, 34, 35, 36, 37, 38, 39)

32. A method of processing denim material, comprising:
-
bringing the denim material into contact with a laser beam by using a conveyor to move said denim into a path of the laser beam;
controlling operating parameters of the laser beam including controlling at least power of the laser beam and moving speed of the laser beam, and also at least one of the parameters from the group consisting of frequency of the laser beam which controls a pulse duty cycle of the laser, wobble of the laser beam which controls an amount of spiraling of the laser beam, and pattern density of scribing carried out by the laser beam, to form a pattern which repeats in a cyclical arrangement, and after said bringing, using the conveyor to bring the material to a washing station.

33. A method of processing denim material, comprising:
-
bringing the denim material into contact with a laser beam by using a conveyor to move said denim into a path of the laser beam; and
controlling operating parameters of the laser beam including controlling at least power of the laser beam and moving speed of the laser beam, and also at least one of the parameters from the group consisting of frequency of the laser beam which controls a pulse duty cycle of the laser, wobble of the laser beam which controls an amount of spiraling of the laser beam, and pattern density of scribing carried out by the laser beam, to form a pattern which repeats in a cyclical arrangement;
wherein said patterns are formed with a frequency between 0.009 and 0.015, a wobble of either 0 or 0.02 and a pattern density between 33 and 100%.

40. A denim processing apparatus, comprising:
-
a conveyer, operating to feed a denim material from a denim source to a first area;
a laser beam, located adjacent said first area, and producing an output beam which impinges on said first area, said laser beam operating with parameters which change a characteristic of said denim material in a specified pattern; and
a rinsing bath, also located in a path of said denim material via said conveyer at a second area, said denim material being conveyed through said rinsing bath by said conveyer, after said conveyer conveys said denim material to said first area. - View Dependent Claims (41)

42. A denim processing apparatus, comprising:
-
a conveyer, operating to feed a denim material from a denim source to a first area;
a laser beam, located adjacent said first area, and producing an output beam which impinges on said first area, said laser beam operating with parameters which change a characteristic of said denim material in a specified pattern; and
a rinsing bath, also located in a path of said denim material via said conveyer at a second area, said denim material being conveyed through said rinsing bath by said conveyer, after said conveyer conveys said denim material to said first area; and
wherein said specified pattern is a substantially random pattern. - View Dependent Claims (43)
