| abstract |
The invention relates to the production of wound-care articles in the form of compresses, which have a cooling effect through swelling in water and which are presented individually in vacuum packaging. According to the invention, successive doses of a powder of absorbent particles are placed in furrows formed by elastic deformation in a lower sheet, which is made of a water-permeable textile material and is unwound in a continuous strip, and then entirely covered by an upper sheet, which is unwound in a continuous strip, parallel to the lower sheet, and is welded to said lower sheet along the intervals between adjacent furrows, thereby isolating the furrows from one another. Then, in each furrow, successive compartments that each contain a dose of said powder are closed by welding said sheets along transverse weld lines across the whole strip. In a subsequent packaging unit, the compresses obtained each receive a sachet of water, with which they are individually enclosed between two impermeable sheets welded to each other around each compress. |
