Abstract
A method for producing a bedding product comprising at least a foamed latex layer, said method comprising the steps of: —pouring liquid latex foam on a conveyor belt; —vulcanizing said liquid latex foam in a vulcanization station to obtain u vulcanized latex foam slab; —cutting said vulcanized latex foam slab to a desired length and/or width, characterized in that for at least partially vulcanizing said liquid latex foam electromagnetic waves with a frequency ranging between 1 and 50 Mhz are used.
Claims13
A method for producing a bedding product comprising at least a foamed latex layer, said method comprising the steps of:
- pouring liquid latex foam on a conveyor belt;
- vulcanizing said liquid latex foam in a vulcanization station to obtain a vulcanized latex foam slab;
- cutting said vulcanized latex slab to a desired length and/or width, characterized in that for at least partially vulcanizing said liquid latex foam electromagnetic waves with a frequency ranging between 1 and 50 Mhz are used.
A slab of vulcanized latex foam for cutting several bedding products therefrom, having a thickness of 6 cm or more, preferably 8 cm or more.
The slab of vulcanized latex foam comprising a locally profiled surface.
A bedding product comprising at least a foamed latex layer, said layer having a compression set of less than 10%, preferably less than 6% after compressing the layer to 50% of its initial thickness for 24 hrs at 70° C.
A device for continuously vulcanizing latex foam, comprising an endless belt, means for pouring liquid latex foam on said belt, a vulcanization station provided along said belt comprising a electromagnetic wave generator for electromagnetic waves having a wave length between 1 and 50 Mhz.
