As shown above, the center ski, which serves to fold down the front minor flap, is mounted on a slotted
bracket. The slotted bracket permits the ski to be adjusted forward or away from the machine in-feed. The
ski is preset at the factory in such a way that the machine can handle a variety of box sizes without frequent
re-adjustment.
The length of the box minor flap determines the adjustment, which usually is a function of box width. When
running boxes that are at or close to the machines minimum and maximum width limits, or boxes with
different flap lengths (i.e. flap cut boxes), it may be necessary to adjust the position of the ski to ensure the
control of the minor flaps.
For boxes that are close to the minimum width, the ski should be adjusted forward, toward the in-feed. This
will ensure the rear minor flap does not spring open before it reaches the ski.
For boxes that are close to the maximum width, the ski should be adjusted in the opposite direction so the ski
does not interfere with the rear minor flap as the Snap Folders fold it.
To run the broader spectrum of box widths that are closer to the machines average width capabilities, the ski
should be set at the midpoint on the mounting slots.
