Abstract

On a plant for the production of the foam springs described in Belgian Patent 859468, the slits in the band of foa m are produced continuously in a pattern extending across the full width of the foam block, by two rollers. The bottom roller supports the material, whilst the upper rollers, provided with cutters distributed over its surface according to a pattern, acts on the bad of foam as it moves between them. Behind the cutting rollers, an adhesive is sprayed on and the edges of the block are turned by rolls and butted together to form a tube for shearing to length.
