CA 2375588

A rolled web of centerflow material, such as paper or non-woven material includes perforation lines separating the material into individual wipes or sheets. Each perforation line comprises a varying perforation profile defined by opposite edge portions and a middle portion having generally the same bond strengths, and intermediate portions between the edge and middle portions having a different bond strength. This perforation profile is effective in reducing dispensing defects, and particularly streaming/roping defects. Alternatively, the perforation line may have stronger edge portions adjacent at least one weaker middle portion.

La présente invention concerne une bande de matériau roulé autour d'un trou central, tel que du papier ou un matériau non tissé. Ces bandes comprennent des moletages séparant ce matériau en tampons ou feuilles individuelles. Chaque moletage comprend un profil de perforation variable défini par les parties des bords opposés et une partie médiane possédant généralement les même résistances d'adhésion, et des parties intermédiaires entre le bord et les partie médianes qui possèdent une résistance d'adhésion différente. Ce profil de perforation est efficace en ce sens qu'il réduit les anomalies, en particulier les anomalies liées à des cassures ou à des entrelacs. Dans une autre option, le moletage peut comporter des parties bord plus solides près d'une partie médiane moins solide.
