Abstract
1424580 Feeding sheets XEROX CORP 8 May 1973 [22 May 1972] 21874/73 Heading B8R In a sheet feeding apparatus having friction separator rollers 12 which are driven first in the reverse direction to buckle a sheet 29 against rear stop 14 and to remove the leading edge of the sheet from beneath pressing members 17 and then in the forward direction for feeding the sheet, the rollers are driven through an elastomeric roll 60 having a longitudinally grooved surface, the roll 60 being driven in the two directions by segmental drive members 62 and 63 each member having a grooved surface, the pitch of the grooves on the roll being different from the pitch of the grooves on the drive members. The roll 60 may be of polyurethane and the drive members of aluminium. The grooves may be V-shaped with those on the roll 60 having an included angle of 90 degrees and those on the drive members having an included angle of 60 degrees. The pile holder may be pivoted at 20 and biased upwardly into engagement with rollers 12 by a spring 22. The members 17 may be reciprocated in the vertical direction to move the pile into and out of engagement with the rollers 12. A pair of nip rollers (50 and 51, Fig. 4, not shown) are provided to forward the separated sheet. The upper nip roller may be a dropping roller to forward the sheets in time with the separating operation.
