Height – 120 mm [4.75 inch] * 510 mm [20.0 inch]
* 100 mm [4 inch] with tape application leg length set at 50 mm [2 inch]. (See "Special Set-Up Procedure,
page 33). Boxes less than 120 mm [4.75 inch] in height must be wider than 170 mm [6.75 inch].

Contact your 3M Representative for information.
Notes:
1. Boxes lower than 165 mm [6.5 inch] and wider than 300 mm [11.75 inch] require removal of
compression rollers.
2. With columns adjusted to upper position, maximum box height increases to 615 mm [24.25 inch] and
minimum box height increases to 205 mm [8.00 inch]. See "Special Set-Up Procedure – Outer
Column Re-Positioning", page 34.
3. The case sealer is designed to accommodate most boxes complying with the 1976 FBA and PMMI
voluntary standard "Tolerances for Top Opening" regular slotted containers (RSC).
Two of the requirements of the standard are the following:
1. The box length is not more than twice the box width.
2. The box length is not more than four times the box height.
In addition, the box score lines must be sufficient to facilitate automatic flap folding. Certain
environmental conditions, such as high humidity, can be detrimental to automatic flap folding.
4. A minimum spacing, equal to 405 mm [16 inch] between boxes at a maximum conveyor speed of 0,30
m/s [60 F.P.M.], must be maintained for boxes entering the case sealer.
5. The case sealer can accommodate most boxes within the size range listed above. However, if the
box length (in direction of seal) to box height ratio is .6 or less, then several boxes should be test run
to assure proper machine performance.
DETERMINE THE BOX LIMITATIONS BY COMPLETING THIS FORMULA:
BOX LENGTH IN DIRECTION OF SEAL SHOULD BE GREATER THAN .6
BOX HEIGHT
Any box ratio approaching this limitation should be test run to assure performance.
