Sealing strip for a roof ridge or arris cover

DETAILED DESCRIPTION It is therefore an object of the present invention to overcome the drawbacks of the prior art and to create a sealing strip which seals and ensures proper ventilation and which can be easily and economically manufactured.
It is yet another object of the present invention to create a sealing strip which can be laid by hand or with the simplest means, and which is universally and permanently adaptable to roof cover boards.
According to the invention, the problem is solved by a sealing strip composed of a soft, plastic, easily deformable material having a center zone for placement on a roof ridge or arris plank.
The center zone comprises a center section and two side sections which are sieve-like and permeable to air.
The strip further comprises lateral zones adjoining each permeable section which are profiled in a pleated-like manner.
The pleats are arranged substantially perpendicular to the longitudinal axis of the sealing strip.
The sealing strip can be easily manufactured using a unitary, soft material, because both the sieve-like production of the air permeable strip section and the pleating can be carried out with relatively simple machines.
This advantageously permits an endless production of a sealing strip from a coil of a ribbon of the soft material.
The finished sealing strips can be cut to size and wound up.
Such a coil can then be easily handled on the roof ridge or arris, and the sealing strip can be installed in the roofing as it is being unwound from the coil.
The soft material makes the sealing strip easily deformable by hand, particularly where the pleating exists and is therefore easily adaptable to profiled roof cover boards.
The pleating permits an expansion of the sealing strip of from 30% to 40% in the longitudinal direction.
The deformation of the sealing strip produced by pressure as it is being fitted to the roof cover boards remains permanent because of the sealing material's plasticity.
The sealing strip can therefore be installed quickly and inexpensively
