Cellular shade material for coverings for architectural openings |
摘要 |
An apparatus and method for fabricating a cellular roller shade material for use in roller shade coverings for architectural openings is described. In a preferred embodiment, two fabric tapes are joined proximate an edge of each to form a wide fabric tape. The wide fabric tape is then pulled through a folding horn to fold the tape along a longitudinal axis that is laterally offset from the tape's longitudinal axis. Two longitudinal adhesive beads are applied to the folded tape by an adhesive applicator. The folded tape is then continuously wound onto tubular surface with the surfaces of the folded tape containing the adhesive beads being placed in an overlapping relationship with a portion of a previously wrapped section of the folded tape. The wrapped and joined tubular tape is cut to form a sheet of shade material that comprises plurality of horizontally-extending cells when utilized in a roller shade.
