Definitions

  • the invention relates to a web, 'in particular of non-woven materials which is divided by separating lines in several in web-longitudinally extending side by side, contiguous and separable strip and to an apparatus for producing the separating lines in the web.
  • the object of the invention is to subdivide the web of material by means of specially designed, but easily insertable, dividing lines into securely connected and tearable strips, the dividing lines resulting in a favorable consolidation of the strip edges.
  • the web of non-woven materials in the most varied of types is divided to form strips by squeezing lines introduced into the web, these squeezing lines each leaving a material film between the adjacent strips, which holds the strips together securely and yet enables these strips to be torn off easily.
  • the squeeze lines which are preferably introduced as longitudinal grooves at a distance from one another, result in a solidification and sealing (similar to a weld) of the edges, so that the strip edges are particularly stable.
  • the pinch lines are preferably introduced from one side of the web to almost over the entire thickness, leaving the thin material film, but they can also be introduced from both sides of the web.
  • Each squeeze line consists of a large number of longitudinal grooves one behind the other, the length of which is greater than

Abstract

L'invention concerne une bande de matériau, en particulier de matériaux non tissés, partagée par des lignes de séparation (3) en plusieurs bandes contiguës (2), parallèles dans le sens longitudinal de la bande de matériau et séparables les unes des autres. La bande de matériau selon l'invention est caractérisée en ce que les lignes de séparation (3) sont formées par des lignes d'écrasement (1) réalisées dans la bande de matériau (W).
