Abstract
A method for producing sealing tape rolls of flexible, compressible foam having at least one external, radially oriented barrier layer comprises the steps of providing a foam web of flexible foam; forming a foam-barrier layer web by application of a barrier layer to a top surface and/or a bottom surface of the foam web; producing a plurality of sealing tape strips by introducing at least one continuous cut into the foam-barrier layer web in a longitudinal direction of the foam-barrier layer web and perpendicularly to the at least one barrier layer; and winding up each sealing tape strip of the plurality of sealing tape strips into a roll in such a way that the at least one barrier layer extends in the radial direction and is arranged on at least one of the two axial end surfaces of the roll.

A method for producing sealing tape rolls of flexible, compressible foam having at least one external, radially oriented barrier layer, the method comprising the following steps, in the order given:
- providing a foam web of flexible foam;
- forming a foam-barrier layer web by applying a barrier layer to at least one of a top surface and bottom surface of the foam web;
- producing a plurality of sealing tape strips by introducing at least one continuous cut into the foam-barrier layer web in a longitudinal direction of the foam-barrier layer web and perpendicularly to the at least one barrier layer;
- and
- winding up each sealing tape strip of the plurality of sealing tape strips into a roll in such a way that the at least one barrier layer extends in a radial direction and is arranged on one of two axial end surfaces of the roll.
A method for producing sealing tape rolls of flexible, compressible foam having at least one external, radially oriented second barrier layer, the method comprising the steps of:
- providing a plurality of foam webs of flexible foam;
- forming a foam-barrier layer web by arranging at least one first barrier layer in each case between a top surface of each first foam web and a bottom surface of each adjacent second foam web facing the top surface of the first foam web;
- bonding the plurality of foam webs to each other along the facing top and bottom surfaces;
- and applying a second barrier layer to at least one of a top or bottom surface of at least one outermost foam web of the plurality of foam webs, which at least one of the top or bottom surface of the at least one outermost foam web faces away from the plurality of foam webs;
- producing a plurality of sealing tape strips by introducing at least one continuous cut into the foam-barrier layer web in a longitudinal direction of the foam-barrier layer web and perpendicularly to the first and second barrier layers;
- and
- winding up each sealing tape strip of the plurality of sealing tape strips into a roll in such a way that the first and second barrier layers extend in a radial direction and at least one second barrier layer is arranged on one of two axial end surfaces of the roll.
