1. Förfarande för svarvning av faner frän en kubb, i vilket förfarande frän mantelytan av en kubb som roteras kring sin längdaxel skärs tangentiellt faner under omständigheter som definieras av avständet (bettavständet) mellan ett skärande bett och ett motbett, som trycker mot kubbens yta omedelbart för skärstället, och det skärande bettet samt motbettet förskjuts mot kubbens rotationsaxel i enlighet med skämingens fortskridande, kännetecknat därav, att i skämingens slutskede minskas avständet mellan det skärande betten och motbettet väsentligen i enlighet med tjockleken av faneret som skärs.
2. Förfarande enligt patentkravet 1, kännetecknat därav, att minskningen av avständet mellan det skärande bettet och motbettet päbörjas väsentligen vid begynnelsepunkten för avslutningsskedet av det skärande bettets rörelse mot kubben.
3. Förfarande enligt patentkravet 1 eller 2, kännetecknat därav, att avständet mellan det skärande bettet och motbettet minskas under avslutningsskedet nägot mera än minskningen av fanertjockleken.
