Model 330HS Adhesive Case Erector / Bottom Sealer

Model 330 high speed case erector and bottom sealer for adhesive sealing at speeds from 20 to 40 cases per minute

Above 30 cases per minute, packagers need a machine with more muscle, yet may find it difficult to justify the cost of added performance for top-end machines. A-B-C's Model 330HS case erector fills this void in the mid-speed (20-40 cpm) packaging range. This powerful erector/sealer is an affordable machine that incorporates solid production features of A-B-C's high-speed models, ensuring top performance from the packaging line.

Features and Benefits

Model 330HS Touchscreen controls

Color Touchscreen gives you total control

The color display shows real-time operating data and allows independent operation of all functions, diagnostics, and changeover settings. Its simple, step-by-step sequences simplify set up and operation. Non-contact sensors monitor machine operation and ensure precise timing of each operating sequence.

Model 330HS Large capacity, easy load case magazine

Large capacity, easy-load case magazine

The self-indexing auxiliary case magazine assures a continuous case supply to the erector. As each stack is used, another moves into position maximizing time between refills. The ergonomic low level design makes it easy to refill without lifting cases.

Model 330HS Case feed designed for smooth operation
Case feed designed for smooth operation

This case erector has self-adjusting, spring loaded grippers that ensure proper case feed from uneven stacks of warped or band-marked cases. Their unique "floating" design allows them to operate independently to grip each case firmly and provide a consistent and reliable case feed.

Model 330HS Reliable case erecting mechanism

Reliable case erecting mechanism

Production-proven since 1990, A-B-C's cam-operated vacuum pullback case opener design is superior in running less-than-perfect corrugated. This method utilizes dual vacuum grippers- lower grippers provide solid compression to hold the case firmly while the upper grippers pull the case open.

Model 330HS Positive flap folding and case transfer

Positive flap folding and case transfer

The major case flaps are gripped firmly as the heavy-duty rear flap tucker folds the inner flap, ensuring efficient flap folding and sealing. The continuous motion main drive powers the walking beam case transfer that squares cases as they travel. The main drive has a sealed bearing linkage that ensures high speed performance for the long haul. 

Model 330HS Servo-operated case compression ram

Servo-operated case compression ram

The servo-operated sealing ram is precisely controlled to enter the case and compress the flaps with optimum precision to ensure secure sealing during high speed production runs.


High speed gravity discharge chute

The simple, stationary gravity discharge uprights cases and channels them to the conveyor under complete control, for seamless, high speed operation. This feature is standard equipment on the Model 330HS to ensure top performance on the case forming line.
