14 Claims

1. A method for producing a plurality of strip-shaped sealing profiles for an edge joint which is formed between a floor and adjacent cladding of drywall, the method comprising:

a) providing a first web of sealing material,

b) applying a plurality of adhesive strips to the first web, wherein adhesive strips of the plurality of adhesive strips each extend in a first direction of the first web, and

wherein adjacent adhesive strips of the plurality of adhesive strips of two adjacent sealing profiles of the plurality of sealing profiles are at a distance from one another in a second direction perpendicular to the first direction, wherein the distance corresponds to at least 50% of a height of a sealing profile of the plurality of sealing profiles,

c) providing a second web,

d) merging and joining the first web to the second web via the plurality of adhesive strips to form a multilayer web, and

e) introducing a plurality of first cuts in the first direction in the multilayer web at a second distance from the plurality of adhesive strips to form the plurality of sealing profiles,

wherein each cut of the plurality of first cuts separates two adjacent sealing profiles of the plurality of sealing profiles from one another,

wherein each cut of the plurality of first cuts is at a first smallest distance from the lower end of an adhesive strip of one of the two adjacent sealing profiles, the first smallest distance corresponding to at most 20% of the height of the sealing profile, and

wherein each cut of the plurality of first cuts is at a second smallest distance from the upper end of an adjacent adhesive strip of the other of the two adjacent sealing profiles, the second smallest distance corresponding to at least 50% of the height of the sealing profile perpendicular to the first direction; and

f) introducing a further plurality of second cuts in the first direction in the first web, to form a stepped profile on the plurality of sealing profiles.
