Abstract
This invention relates to a method of sewing large area sewing material consisting of plural and at least two layers, of which at least one layer is formed of an elastical material, for instance foamed material, wherein said layers are fed to the sewing unit in a superposed relationship and wherein the layer of elastical material is fed to the sewing unit in an unexpanded and preferably bulged condition and is stitched together with the layer formed of non-elastical material. Such a method offers the advantage that the formation of folds in the stitched product is prevented in a simple and inexpensive manner.
