Patent ID: 6941860

Claim:
A method for briquetting metal chips in a briquetting press by pressurization of a pressed article by at least one press ram in a pressing sleeve, into which metal chips are fed via a metering device assigned radially to the pressing sleeve using a stamper, comprising the steps of (a) advancing the stamper for filling the pressing sleve with the metal chips and closing the pressing sleeve; (b) advancing the pressing ram and feeding the metal chips into the press section of the pressing sleeve; (c) pressurizing the metal chips by the at least one press ram until a final pressure P max or required pressure P req is reached and a pressed article is formed; (d) retracting the at least one press ram and ejecting the pressed article as a briquette and retracting the press ram into a starting position; wherein during the application of pressure (P.sub.max or P.sub.req) with the press ram, an actual attained length of the pressed article (L.sub.actual) is measured and the measured actual attained length of the pressed article is compared to a nominal length (L.sub.nominal) of the pressed article to determine a difference value (.DELTA.) between the actual attained length (L.sub.actual) and the nominal length (L.sub.nominal), and a quantity or mass of the metal chips that the metering device has to supply is determined from the difference value (.DELTA.) according to the nominal length (L.sub.nominal) of the pressed article, followed by adjusting a filling mass of the metal chips in the metering device and supplying the corresponding quantity or mass of the metal chips by the stamper.
