Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
122 words
A method of cutting a patterned array of holes in a moving web of flexible material including the steps of: moving the web in a continuous manner so that at least a portion of the web is in a substantially flattened state while moving, positioning the portion of moving web in the flattened state adjacent to a series of rotating cutters having circular cutting edges, such cutting edges being arranged in a patterned array in an imaginary plane parallel to the flattened portion of the web, and driving a transverse portion of the web from its flattened state into momentary contact with the rotating cutting edges so as to remove circular pieces of web material in a patterned array across the web.
Claim 2
Independent Claim
122 words
A method of cutting a patterned array of holes in a moving web of flexible material including the steps of: moving the web in a continuous manner so that at least a portion of the web is in a substantially flattened state while moving, positioning the portion of moving web in the flattened state adjacent to a series of rotating cutters having circular cutting edges, such cutting edges being arranged in a patterned array in an imaginary plane parallel to the flattened portion of the web, and driving a transverse portion of the web from its flattened state into momentary contact with the rotating cutting edges so as to remove circular pieces of web material in a patterned array across the web.
Claim 3
Independent Claim
132 words
A method of cutting a patterned array of holes in a moving web of flexible material including the steps of: moving the web of flexible material in a continuous manner so that at least a portion of the web is in a substantially flattened state while moving; positioning the portion of the moving web in the flattened state adjacent to a series of rotating cutters having circular cutting edges that are arranged in a patterned array in an imaginary plane parallel to the portion of the web that is in a substantially flattened state; and urging, by means of air jets, a transverse portion of the flattened web into momentary contact with the rotating cutting edges so as to remove circular pieces of web material in a patterned array across the web.
