Abstract
Abstract Described herein is a stamped cushioning piece of a two-layered latex foam, produced with paddings in various places from a latex foam of greater specific weight. First, a layer of latex foam of slight specific weight is applied to a textile carrying sheet. Into this, depressions are stamped, whereupon a second layer of latex foam, preferably of a high specific weight, is applied. Manufacture occurs continuously on so-called large-scale machines, and the pieces are stamped out of the sheet.
