Abstract
A method of forming a single-cell column type of multi-cellular collapsible window covering from a starting product in the form of a double-cell column type of multi-cellular honeycomb structure. The individual cells of the starting product are defined by external pleated sides on the opposite faces of the structure and internal ligaments interconnecting the opposite faces at spaced intervals. Selected internal ligaments are severed, while leaving others of the internal ligaments intact, thereby eliminating one of the original columns of cells.
Claims21
A method of forming a window covering from a starting product in the form of a multiple-columned honeycomb structure, wherein the individual cells of the starting product are defined by external pleated sides on the opposite faces of the structure and internal ligaments interconnecting such opposite faces at spaced intervals and serving as a partition between adjacent cells of different columns of cells, the method comprising the steps of:
- severing selected ones of the internal ligaments, while leaving others of the internal ligaments intact, thereby eliminating at least one of the individual cells of the starting product.
A method of forming a multi-cellular collapsible window covering from an starting product in the form of a double column type of multi-cellular honeycomb structure, wherein the individual cells of the starting product are defined by external pleated sides on the opposite faces of the structure and internal ligaments interconnecting such opposite faces at spaced intervals and serving as a partition between adjacent cells of different columns of cells, the method comprising the steps of:
- severing selected ones of the internal ligaments according to a predetermined repeating sequence, while leaving others of the internal ligaments intact, thereby eliminating at least one of the individual cells of the starting product.
A method of forming a multi-cellular collapsible window covering from an starting product in the form of a multiple-columned honeycomb structure of a Type 1:1 configuration, wherein the individual cells of the starting product are defined by external pleated sides on the opposite faces of the structure and internal ligaments interconnecting such opposite faces at spaced intervals and serving as a partition between adjacent cells of different columns of cells, the method comprising the steps of:
- severing selected ones of the internal ligaments, while leaving others of the internal ligaments intact, thereby eliminating at least one of the individual cells of the starting product.
