The experimental study of the effect of the dimensions of the feed mechanism and the properties of powder upon the relative thickness of copper and iron layers in pore-free strip was carried out. An equation is suggested for the calculation of the relative thickness of copper layers in pore-free strips prior to rolling; this equation takes into account the setting of the feed apparatus and the properties (volume weight) of powders. The calculated data is in good agreement with experimental results. The agreement of the three-layer metal-powder strip with the standard specifications is not worse than that of the strip made of laminated ingots.
