ABSTRACT:
A continuous process for producing strip products which comprises forming an aqueous slurry of a mixture of a metal powder and a film-forming cellulose derivative and producing from this slurry a self-supporting strip. This self-supporting strip is fed onto an endless moving belt by which the strip is transported into and through a sinter furnace. A tensile force is applied to the sintered strip in the direction of travel of the strip, and this tensile force is controlled such that the speed at which the strip leaves the furnace is greater than the speed at which the strip enters the furnace by an amount related to the expected or actual increase in strip length occasioned by expansion of the strip during the sintering process.
