Abstract:
A sheet feeder comprises a feed deck for supporting a stack of sheets
(65) to be fed. The feed deck may be formed by a bed of freely spinning
rollers. A feed block (62) comprises a friction pad (66) that projects
from the bottom of the feed block (62) towards a drive belt (42) to
define a gate therebetween. The drive belt (42) frictionally engages the
underside of a bottom sheet of the stack (65) and urges the sheet towards
the gate. The feed block (62) comprises a front face (72) immediately
upstream from the gate, which is inclined at a sharp angle to the feed
direction. The friction pad (66) comprises a lower face that is
substantially parallel to the feed direction and does not intersect the
plane of the feed block front face (72).Claims:
