Abstract
The improvements are applicable to manufacturing processes in which use is made of a shaping device 2-2' defining an openable chamber which coincides in terms of shape and dimension to the mattress to be obtained, in such a manner that the textile covering 8 of the mattress is introduced inside said chamber and adapted to the walls of the shaping device 2-2' and the foaming material which is to shape the elastic body of the mattress is introduced inside said textile casing. The improvements consist in establishing a leaktight seal for the shaping device 2-2' and applying to the chamber formed thereby, during foaming, a reduced pressure generated by a vacuum pump 6 optionally assisted by a vacuum tank 7, connected preferably to the actual overflow of foam 3 of the shaping device 2-2'.
