An elongate continuous material web is disclosed that includes a plurality of adjacent tabs arranged in a longitudinal direction of the web with connection regions between adjacent tabs. Each connection region includes three or more incisions that extend in the transverse direction of the web and are arranged in a manner such that at least one extensible connection member, extensible in the longitudinal direction of the web, is formed. At least one incision forms a side incision that travels through one longitudinal edge of the web, and at least one incision forms a further side incision that travels through the other longitudinal edge of the web. Also disclosed are a method for making such a web, a method for manufacturing a tab from such a web, a method for manufacturing an absorbent hygiene product with the help of such a web, and a cutting device to produce such a web.
An elongate continuous material web comprising a plurality of adjacent tabs arranged in a longitudinal direction of the web and connection regions between adjacent tabs, wherein at least one main surface of the web is at least partly provided with an adherent agent selected from the group consisting of hooks, loops, adhesives, and mixtures thereof, wherein each connection region comprises at least three incisions that extend in the transverse direction of the web and are arranged in a manner such that at least one extensible connection member, which is extensible in the longitudinal direction of the web, is formed, wherein at least one incision forms a side incision that travels through one longitudinal edge of the web, and wherein at least one incision forms a further side incision that travels through the other longitudinal edge of the web.
An elongate continuous material web comprising a plurality of adjacent tabs arranged in a longitudinal direction of the web and connection regions between adjacent tabs, wherein each connection region comprises at least three incisions that extend in the transverse direction of the web and are arranged in a manner such that at least one extensible connection member, which is extensible in the longitudinal direction of the web, is formed, wherein at least one incision forms a side incision that travels through one longitudinal edge of the web, wherein at least one incision forms a further side incision that travels through the other longitudinal edge of the web, wherein at least one of the connection regions comprises two of the extensible connection members arranged side by side in the transverse direction of the web and separated from each other by a separating incision that extends in the lengthwise direction of the web, wherein each of the two extensible connection members comprises at least three incisions that extend in alternating manner from the separating incision to almost one longitudinal edge of the web and through said longitudinal edge to almost the separating incision.
An elongate continuous material web comprising a plurality of adjacent tabs arranged in a longitudinal direction of the web and connection regions between adjacent tabs, wherein each connection region comprises at least three incisions that extend in the transverse direction of the web and are arranged in a manner such that at least one extensible connection member, which is extensible in the longitudinal direction of the web, is formed, wherein at least one incision forms a side incision that travels through one longitudinal edge of the web, wherein at least one incision forms a further side incision that travels through the other longitudinal edge of the web, wherein at least one of the connection regions comprises three of the extensible connection members, one inner extensible connection member and two outer extensible connection members, arranged side by side in the transverse direction of the web, wherein the inner extensible connection member is separated from the two outer extensible connection members by separating incisions that extend in the lengthwise direction of the web, wherein the inner extensible connection member comprises at least three adjacent incisions that extend from one of the separating incisions to almost the other in alternating manner, and wherein the outer extensible connection members comprise at least three adjacent incisions which extend in alternating manner from the separating incisions to almost one longitudinal edge of the web and through said edge to almost the separating incisions.
