Zusammenfassung:	The present invention provides a dual slip cut unit (2100). The dual slip cut unit comprises: a rotating anvil (2106); a first rotating knife (2104) engageable with the rotating anvil (2106) to cut a plurality of severed pieces (2102') from an extension panel web (2102); a second rotating knife (2104) engageable with the rotating anvil (2106) to cut each severed piece (2102') into first and second subdivided pieces (2102''); and a transfer drum (2108) configured to receive the first and second subdivided pieces (2102'') from the rotating anvil (2106). The rotating speed of the rotating anvil (2106) creates a first gap between adjacent severed pieces (2102') and the rotating speed of the transfer drum (2108) creates a second gap between adjacent first and second subdivided pieces (2102'').
