  • a whole length of filter tape could be removed from the roll and the release paper be peeled away in its entirety before applying the filter material to the tile.

  • a further advantage is that less waste is produced on site during use of the filter tape. Also, release paper is a low-friction product which has been known to cause accidents due to slipping if left on the floor. Further, if the release paper is not used during manufacture of the filter tape, to apply the adhesive to the filter material, less material waste occurs during the manufacturing process.

Abstract

L'invention concerne un procédé de fabrication d'une bande filtre au moyen d'un papier détachable (3), et une couche de matière filtre (4). Des lignes adhésives (1) sont formées sur la bande filtre (2) par application d'adhésif sur le papier détachable (3). L'adhésif colle de préférence à la bande filtre (2) plutôt qu'au papier détachable (3). Des informations peuvent être imprimées sur une surface de la couche de matière filtre (4), notamment afin de montrer l'orientation d'un bloc/pavé auquel la bande est appliquée. Dans un autre mode de réalisation, un agent de libération notamment du silicone est appliqué directement sur la couche de matière filtre (4) ne rendant pas nécessaire le papier détachable (3).
