and Townsend (the modified AAPA). Thus, we shall focus our attention on the
teachings of Lambert, Garrett and Santanna taken in combination with the modified
AAPA.
Lambert, Garrett and Santanna are all directed to circumferentially adjustable
rotary cutting knives for use in cutting slots in paperboard blanks used to make cartons
or boxes. The slotter devices used to cut the slots in the paperboard blanks comprise a
wheel or upper slotter member (such as upper slotter member 14 of Lambert) on which
are mounted two cutting blades, at least one of which is mounted on the wheel or slotter
member in a circumferentially adjustable manner so that the spacing between a leading
edge slot (such as slot 212 of Lambert) and a trailing edge slot (such as slot 216 of
Lambert) can be adjusted to accommodate different sized blanks to form different sized
cartons or boxes. The cutting blades are received in a circumferentially extending slot
(such as slot 200 of Lambert) in a backing wheel (such as lower slotter member 198 of
Lambert).
While Lambert, Garrett and Santanna are silent as to the reason for using a
circumferential slot in the backing wheel (lower slotter member) of their slotter device,
rather than, for example, a circumferentially short recess aligned with the cutting blade2,
an artisan reading their disclosures would infer that a circumferential slot is used so as
to accommodate the circumferentially adjustable cutting blade on the upper slotter
2 Such would be akin to the recesses 35 in roller 34 aligned with punches 33 on drum 32 in
Townsend’s irrigation tape foil punching means.
