Patent ID: 8153219

Claim:
A tape for closing an opening in a substantially dustproof but ventilating manner, comprising: an elongate strip of fabric with an open pore structure, and a glue layer on substantially an entire surface of the strip of fabric in a predetermined pattern, wherein, the glue layer is applied on a central part of the surface between edge parts of the tape in a first pattern such that the glue layer completely closes the open pore structure at distinct locations on the surface so that ventilation is no longer possible through the tape at the distinct locations, the open pore structure remaining open at other distinct locations and the open pore structure remaining open at other distinct locations such that ventilation is possible through the tape at the other distinct locations, and the glue layer is applied on either side of the central part along the edge parts of the elongate strip of fabric in a second pattern that is more dense than the first pattern.
