beneath the supporting plate 22 mount the cam wheels for rotation
such that the entirety of each wheel lies below the supporting
plate during one phase of rotation and a portion of the wheel
extends above the plate through a slot therein during a second
phase of rotation. In operation, “the feed device and the
aligning device act upon the sheet to be picked from the stack at
different times. Said sheet is then transported alternately in
the alignment direction and the transport direction until it
reaches the picking device” (column 1, lines 38 through 42).
Mylaeus teaches that this operational mode results from the
particular relationship between the cam wheels:
[d]riving wheels 31, 41 and 51 of cam wheels 30,
40 and 50 are dimensioned so that firstly the cams of
cam wheels 30 and 40 and secondly the cams of cam
wheels 50 pass through supporting plate 22
simultaneously. The cams of cam wheels 30 and 40
preferably pass through supporting plate 22 with a
constant phase shift in time relative to the cams of
cam wheels 50 so that the cams of cam wheels 30 and 40
of the feed device and the cams of cam wheels 50 of the
aligning device act alternatingly at least upon sheet
11 to be picked from stack 10.
. . .
Through the action of friction belts 33 and 45
laid around cam wheels 30 and 40 upon passage of the
cams through supporting plate 22, at least sheet 11 to
be picked from stack 10 is first transported a certain
distance in the transport direction. The cams of cam
wheels 30 and 40 then pass through supporting plate 22
again so that friction belts 33 and 45 no longer
interact with sheet 11. Parallel thereto the cams of
cam wheels 50 pass through supporting plate 22 so that
friction belts 55 act at least upon sheet 11 of stack
