For packagers seeking a top case sealer that accommodates
case variations and ensures square cases that palletize well, the
solution is the Model 336 top case sealer. This compact case sealer
runs cases at speeds to 45 cases per minute, with a continuous operation
design that accepts cases that are fed spaced or back-to-back, and
provides automatic flap folding and sealing.
There are several features that are key to forming square cases;
most important is the powered compression section with dual top
and bottom belt drive. This unique feature combines the bottom case
drive belt with a powered upper belt drive to convey the case and
provide secure compression as the adhesive sets. The top belt drive
pulls the case through compression and prevents the major flaps
from skewing which happens in non-powered units. Spring-loaded rollers
under the belt adjust to variations in case height, ensuring a secure
seal. Additional features include the contoured flap folders that
gently close the flaps while a steel tongue rides in the center
to prevent flap overlap.
