Abstract
A tape for closing an opening in at least substantially dustproof but ventilating manner includes an elongate strip of fabric (10) with an open pore structure (11). The strip is provided according to a pattern (13) with a layer which at least substantially completely closes the pores locally and on a rear side with a glue layer in opposite edge parts (12). The glue layer is arranged between the edge parts (12) in accordance with the pattern and at least almost completely closes the pores (11) locally.
Claims15
Tape for closing an opening in at least substantially dustproof but ventilating manner, comprising an elongate strip of fabric with an open pore structure, which strip is provided according to a pattern with at least one layer which at least substantially completely closes the open pore structure locally and on a rear side is provided with a glue layer in opposite edge parts, characterized in that the glue layer completely closes the open pore structure locally, that the glue layer is arranged in accordance with the pattern at least between the edge parts on the rear side of the strip, and that the glue layer thus forms the at least one layer which at least almost completely closes the open pore structure locally.
Method for manufacturing a tape intended to close a cavity in at least substantially dustproof yet ventilating manner, wherein a fabric with an open pore structure is provided, in accordance with a pattern, with a layer which at least substantially completely closes the open pore structure locally, and is formed into at least one strip with a width of between about 20 and 100 millimetres, characterized in that the layer comprises a glue layer and is arranged in accordance with the pattern on a rear side of the fabric.
