Appeal No. 2003-0550
Application No. 09/580,411
As noted on page 1 of the specification, appellant's
invention is directed to a die cutter apparatus for severing
blisters into individual blisters from a sheet of blisters which
has been formed from a deformable transparent or translucent
sheet of plastic material by a process known to those skilled in
the art. More specifically, independent claim 1 on appeal
provides for a "compensating blister die cutting apparatus"
including, inter alia, a lost motion connection connecting each
blister die cutter unit support member (50) to the base member
(31) of the die cutter apparatus and permitting relative lateral
movement of each die cutter unit (34-39) relative to the base
member and relative to each other through a range of 360 degrees.
The "lost motion connection" described on page 6 of the
specification includes threaded adjustment members (70) being of
a smaller diameter than the holes (72) in the top board (50),
backup plate (47) and bottom board (44) so that the die cutter
units can move relative to the base member and relative to each
other when a blister on a blister sheet is pushed down into the
cavity (62) of a given die unit which causes that unit to shift
so that a given blister fits into a given cavity in a symmetrical
fashion. A copy of independent claim 1 on appeal, as reproduced
