Abstract:
1. A method of processing segments of a continuous flexible web wherein a length of the web is incrementally advanced under tension to successively feed at least one segment of the web to a web processing station having processing components for cutting the flexible web, said method comprising: intermittently releasing tension on the length of the web while said at least one segment thereof is at the processing station; holding each said successive segment of the length of the web using a holder while the segment is positioned at the web processing station; using the holder to continue to hold the held segment of web at the processing station while allowing the held segment to move relative to adjacent portions of the web due to said released tension on the length of the web, the holder holding said held segment being moveable in an X axis direction of feed of the length of the web to the processing station, in a Y axis direction transverse of the X axis direction, and about a θ axis of rotation of the holder perpendicular to said X and Y axis directions; accurately adjusting the position of the held segment of the web at said processing station prior to processing thereof by subjecting the holder holding said held segment to controlled adjustment motion selected from the group consisting of motion along said X axis, motion along said Y axis, motion in the form of rotation about said θ axis, and simultaneous combinations of said motions as required to obtain accurate alignment of the held segment of the web with the processing components at said processing station; and processing each held segment by cutting each held segment using said processing components within the station after said accurate adjustment thereof.
