Abstract
A method of sealing the join between two tapes to which the teeth of a waterproof zip are attached and two edges of a garment composed of a first or waterproof layer and a second or fabric layer, which comprises: a) applying to a first side of each tape, a strip of heat-weldable textile material attached to it, by at least one weld line, such that each strip comprises a first and a second flap; b) welding the edge of the first layer to one face of the flap furthest from the teeth; c) attaching the edge of the second layer to the second side of each tape; d) folding down the flap nearest to the teeth of the zip; and e) forming another weld that hermetically joins the outline of the outer edges of the flap to the corresponding tape around the area.

Method of sealing the join between two tapes (2,3) to which teeth (4,5) of a waterproof zip (1) are attached and two edges of a garment composed of a first or waterproof layer (7) and a second or fabric layer (8), these layers being superimposed on each other, which method is characterized in that it comprises the following steps:
- a) applying, to a first side (2e,3e) of each of the said two tapes (2,3), a strip (9) of heat-weldable textile material attached to it by at least one weld line (L) formed along a longitudinal line, in such a way that each strip (9) comprises a first unattached flap (9f) and a second unattached flap (9s), one on each side of the said weld line (L) and both parallel to the lines of teeth (4,5) of the zip (1);
- b) welding the edge of the said first or waterproof layer (7) to one face of the flap (9s) furthest from the teeth (4,5) of the zip (1);
- c) attaching the edge of the said second layer (8) to the second side (2i,3i) of each of the said tapes (2,3) by means of a seam (K) in an area (Z) situated between the said weld line (L) and the zip (1);
- d) folding down the flap (9f) nearest to the teeth (4,5) of the zip (1) so that it lies parallel against the said first side (2e,3e) of the corresponding tape (2,3) and entirely covers the said area (Z);
- and
- e) forming another weld (N) that hermetically joins the outline of the outer edges of the flap (9f) to the corresponding tape (2,3) around the said area (Z).
