Abstract

As shown by the differences in component positions between the -MO figures, partial rotation to the Figure 2 position of a single cam 1 causes the fingertips of a spring metal registration or deskewing gate 2 to be moved out of the sheet 3 movement path by one end of the cam and then shortly thereafter the other (shorter) end of cam 1 slightly lifts a low friction sheet guide 4 as in Figure 2 to press the sheet 3 against high friction feed rollers 5 to provide sufficient normal (nip) force therebetween so that the deskewed sheet 3 is driven out, as in Figure 2, whereas in Figure 1 the sheet guide 4 provides space for the sheet to slip in a loose nip while being deskewed (squared) by its lead edge being driven against gate 2 by flexible soft nip upstream drive rollers 6.
