• the two-sided sewing is not mandatory and in any case, it requires the presence of two-sided flap-shaped welds 11. If by means of the belt 20, the surrounding sheath 12 is formed, it will be advantageous to use a hem band sew the flap-shaped weld. This increases the strength and protects the inflatable body against damage, while at the same time projecting no disturbing relatively hard seam on the mobile deck substructure.

It is usually an open-cell foam with large pores can be compressed very compactly and with a great restoring force it is able to expand after compression into its original form. With the valve 13 open, such inflatable bodies 10 can easily be rolled up and as soon as the longitudinal bars 1 formed by the inflatable body 10 are completely rolled up, the valves 13 can be closed and the longitudinal bars remain in the corresponding state.
