Appeal No. 2000-1639
Application No. 08/923,449
Appellant’s invention pertains to an apparatus for
decelerating and shingling “signatures.”2 With reference to
appellant’s Figure 1, the apparatus includes a folder (2) for
folding a web (1), cutting cylinders (11.1, 11.2) for cutting the
web into individual signatures, and a tape system (20) comprising
first and second tapes or belts (23, 24) forming an arcuate path
for receiving the individual signatures, the tape system running
at a tape system speed greater than the web speed. The apparatus
further includes a first conveyor (30) having a first knock-down
wheel (31) downstream of the tape system for receiving signatures
from the tape system, the first conveyor running at a first
conveyor speed slower than the tape system speed thereby forming
the signatures into a first stream of shingled signatures
traveling at the first conveyor speed, and a second conveyor (33)
having a second knock-down wheel (34) downstream of the first
conveyor for receiving the first stream of shingled signatures,
the second conveyor running at a second conveyor speed slower
2According to Webster’s II New Riverside University
Dictionary (copyright © 1984 by Houghton Mifflin Company), the
word “signature” may mean “[a] large sheet printed with four or a
multiple of four pages that when folded becomes a section of [a]
book.”
