METHOD OF MANUFACTURING SEAMS WITH EDGE CRIMPING Russian patent published in 2018 - IPC F16B11/00 

FIELD: textile, paper.

SUBSTANCE: method for manufacture of a seam contains the following operations: manufacture of adhesive structural element, the length of which corresponds to the length of future seam gap and, in a cold state, is shorter than the length of the seam gap. The adhesive structural element has an expanding structural adhesive, the adhesive structural element is applied in a cold state to the side of one of the components facing the other component, the crimped edge is folded towards the inner component. The adhesive structural element with an excess of length is crimped at the latest when the crimped edge is folded around the free edge of the inner component. The adhesive structural element after folding the crimped edge toward the inner component is inside the seam gap with its free edges, so that an appropriate expansion space is formed, at least a part of the seam is heated melting the structural adhesive so that it protrudes from the seam gap, spreading in all directions, and forms a seal thickening.

EFFECT: increase in the protection of the seam against corrosion and unintended air entry.
