The process, designed to produce a sleeve (1) with at least one airtight tube (2) from two superimposed layers of a coated fabric, consists of cutting strips (15, 25) from a separate layer of fabric, coated on one face, applying adhesive to the non-coated face and folding them in half lengthwise with the adhesive on the inside to hold them together. The folded strips are then fixed in pairs at appropriate intervals to one of the layers of coated fabric with their open edges facing one another. An anti-adhesive coating is applied between them, and the second layer is stuck on top of the first, creating one or more tubular sections that can be inflated, with connecting strips (3) between them. |
