Abstract

A rear edge registration system 10 for a recirculating vacuum corrugation feeder is disclosed in Figures la and lb that includes the use of vacuum air flow to pull the bottom most sheet in a stack supported by tray 20 down against a counterclockwise rotating scuffer registration wheel 15. Blades 13 cause wheel 15 to rotate. The blades could be rotated by an electric motor or the vacuum air flow as shown. Sheets are fed from the tray in the direction of arrow 30.

VACUUM REGISTRATION FOR A RECIRCULATING VACUUM CORRUGRATION FEEDER (Cont'd)

A rear edge registration system 10 for a recirculating vacuum corrugation feeder is disclosed in Figures la and lb that includes the use of vacuum air flow to pull the bottom most sheet in a stack supported by tray 20 down against a counterclockwise rotating scuffer registration wheel 15. Blades 13 cause wheel 15 to rotate. The blades could be rotated by an electric motor or the vacuum air flow as shown. Sheets are fed from the tray in the direction of arrow 30.

The principal advantage of this system over vertical scuffing rolls now in use is improved scuffing action due to enhanced contact with sheets in the stack. Another advantage is the reduction in multifeeding due to increased sheet two pullout friction. Also, reliability will be improved since the scuffer roll 15 will not be cut by sheets in the stack as happens with vertical registration rolls.
