How to Adjust For Case Sizes (BEL 5252)

Use the following instructions to set up the BEL 5252 to form and seal a particular case size with adjustments for case length (C), closed height (H), case width (D), and flap width (G).

IMPORTANT - Switch the machine OFF by pushing down the red ‘EMERGENCY STOP’ button before making any changes or adjustments.

There are illustrated case size adjustment instructions on the top of the left-hand side of the frame rail.

There is only a single adjustment for case length in the case former section of the machine. The rear minor flap folder ‘tower’ slides along the bottom frame member to adjust for case length. Release the locking screw ‘T’ lever at the base of tower, position it according to the length scale, and re-tighten it.

Unlock the height adjustment and rotate the hand wheel to raise or lower the top flap folder and tape head sub-assembly to the correct case height.

Attach the hand crank supplied with the machine on the square shaft that extends from both sides of the frame. Adjust the width using the reference scale under the sealer conveyor on the left hand side of the machine.

Loosen Snap Folder locking handles and adjust to the case width. There should be 1/16” – 1/8” [1.6mm – 3mm] of clearance on each side between the folder guide bar and the side of the case. Re-tighten the locking handles.

The case former section major flap folder roller plates need to be adjusted in or out according to the case width. If left too far out, they will jam the machine when the width is adjusted for narrow cases. If not adjusted out for wide cases, they will not fold the flaps effectively or provide support for product in the center of the case.

For RSC cases, G = ½ D. The top ski must be adjusted so that the rear minor flap does not hit it when folding down. The ski also must not be adjusted too far back or the flap will unfold before it is under the ski, also hitting it and damaging the case.
