An apparatus whereby the seal score and bottom score is made on the seal and bottom flaps respectively of envelopes or bag blanks. The apparatus provides for split scoring and an adjustment for different size envelopes or bag blanks. Size changes are accomplished by a running adjustment of the one scorer, relative to the other scorer which remains fixed. The construction is such that the pull-out segment engages each envelope blank at a precise location so that the distance on the envelope blank for the first scoring operation thereon is always predetermined. Thus, a fine running adjustment is permitted along with quick size changes for envelopes or bag blanks. The scoring knives also may be mounted on a common cylinder. |
