4100T FS3 Semi-Automatic Pallet Wrapper

Three-Post Rotary-Arm Wrapping for Stationary Loads

The 4100T-FS3 pallet wrapper uses a free-standing three-post frame and powered rotary arm to wrap pallets while they remain stationary on the facility floor. This design makes the machine especially useful for heavy, tall, lightweight or unstable loads that may shift when rotated on a conventional turntable.

Moreover, the three-post structure creates a dedicated wrapping zone without requiring support from a building wall or overhead structure. Operators position the pallet inside the frame, attach the stretch film and start the automatic wrapping cycle. As a result, the FS3 combines stationary-load stability with straightforward semi-automatic operation.

Benefits of the 4100T-FS3 Pallet Wrapper

• Stationary load wrapping: The pallet remains on the facility floor while the rotary arm applies film.
• No machine-imposed weight limit: Instead, the facility floor and material-handling equipment determine practical capacity.
• Three-post free-standing frame: The structure creates a defined wrapping cell without requiring wall support.
• Improved load stability: Consequently, unstable or lightweight products avoid turntable rotation.
• Up to 30 loads per hour: Actual production depends on load height, wrap counts and handling time.
• Powered pre-stretch: Meanwhile, the film carriage improves film yield and containment consistency.
• Simple utility requirements: The standard machine operates on 115-volt power without compressed air.
• Expandable design: Finally, customers can add guarding, extended frames, taller towers or scale packages.

4100T-FS3 Pallet Wrapper Specifications

Production and Load Capacity

• Production speed: Up to 30 loads per hour
• Maximum machine-supported weight: Unlimited because the facility floor supports the load
• Maximum load width: 50 inches
• Maximum load length: 50 inches
• Maximum load diagonal: 71 inches
• Maximum load height: 86 inches

Although the wrapper does not impose a turntable weight limit, the floor, pallet and forklift must safely support the load. Therefore, Ameripak should review unusually heavy applications before finalizing the system.

Free-Standing Three-Post Frame

The FS3 frame uses three structural posts to support the rotary-arm assembly and define the wrapping area. Unlike wall-mounted or rear-mounted configurations, it does not depend on a building wall for structural support.

• Frame arrangement: Three structural posts surround the wrapping zone.
• Loading access: The open side provides forklift or pallet-jack access.
• Floor mounting: Proper anchoring secures the frame during rotary-arm operation.
• Structural construction: Heavy-duty steel supports industrial use.
• Machine covers: Sheet-metal panels protect internal components.
• Protective finish: Finally, electrostatic powder coating helps resist corrosion and wear.

Because the frame surrounds multiple sides of the load, Ameripak should review forklift approach, pallet orientation and available floor space during layout planning.

Powered Rotary-Arm System

The rotary arm travels around the stationary pallet while the film carriage moves vertically. Therefore, the pallet avoids the centrifugal force and movement associated with a turntable wrapper.

• Arm support: A double-flange bearing system supports controlled rotation.
• Drive arrangement: Twin V-belt pulleys include a belt tensioner.
• Rotational speed: Operators can adjust the arm from 1–12 RPM.
• Acceleration: Soft-start control reduces sudden movement at the beginning of the cycle.
• Final positioning: Additionally, controlled deceleration provides positive stop alignment.
• Arm motor: A 1/2 HP DC variable-speed motor powers rotation.
• Dynamic braking: Finally, the braking system controls rotary-arm and carriage movement.

Powered Pre-Stretch Film Delivery

The 4100T-FS3 pallet wrapper includes the Cousins Super Rapid Thread II™ 20-inch powered pre-stretch carriage. Its threading path maximizes film contact with the rollers and correctly positions the film’s cling side toward the load.

• Pre-stretch range: Fixed ratios extend from 33% to 313%.
• Ratio adjustment: Simple sprocket changes match pre-stretch to the selected film.
• Corner compensation: Additionally, electronic dynamic dancer control regulates film delivery around load corners.
• Carriage motor: A 1/2 HP AC variable-speed motor controls film output.
• Rapid threading: The special device simplifies film-roll installation.
• Safety interlock: Opening the Rapid Thread™ door interrupts carriage power.
• Film contact: Greater roller coverage helps reduce slipping during operation.
• Roller coverage: Finally, Cousins provides a lifetime warranty on the pre-stretch rollers.

Consequently, the carriage can improve containment consistency while helping facilities manage film consumption.

Film-Carriage Elevator

• Elevator motor: A 1/2 HP AC variable-speed motor moves the carriage.
• Drive system: A direct flat belt provides smooth vertical movement.
• Guidance system: Twelve maintenance-free points keep the carriage aligned.
• Speed control: Meanwhile, independent raising and lowering adjustments control film overlap.
• Dynamic braking: Controlled stopping supports repeatable carriage positioning.

Programmable Wrapping Controls

Wrap-Pattern and Film Controls

The Panasonic PLC provides straightforward access to the semi-automatic wrapping functions.

• Cycle start: A single button starts or pauses the automatic cycle.
• Wrap direction: Operators can select an up-only or up-and-down pattern.
• Starting position: In addition, the program can apply base wraps or top wraps first.
• Top and bottom wraps: Separate settings provide from 1–9 revolutions.
• Film tension: Force-to-load control adjusts containment pressure.
• Carriage speed: Independent raising and lowering settings control film overlap.
• Rotary-arm speed: Variable control helps match movement to load stability.
• Reinforcement: Finally, the mid-cycle reinforce function adds film to selected areas.

Operator and Safety Controls

• Top-sheet pause: Operators can pause the cycle to apply a protective sheet.
• Load-height detection: A triple-beam photo-eye recognizes dark or reflective products.
• Manual arm movement: Additionally, the rotary-arm jog switch assists with setup.
• Carriage positioning: Raise and lower controls allow manual adjustment.
• Power functions: Off, on and reset controls include a power indicator.
• Emergency stop: A dedicated button stops machine operation.
• Control enclosure: The NEMA 12 panel protects industrial components.
• Electrical components: Finally, non-proprietary UL/CSA-approved parts simplify service.

Rotary-Arm Safety System

The 4100T-FS3 includes an obstruction-sensitive emergency-stop device on the rotating arm. If the arm contacts an unexpected obstruction, the sensor stops rotation to help protect personnel, the pallet and the equipment.

However, the rotating arm still requires a controlled operating zone. Ameripak should review forklift travel, pedestrian access and required clearances before installation.

Optional side fencing and a front sliding gate can further control access. Moreover, the optional gate interlock can prevent operation while personnel enter the wrapping area.

Electrical and Installation Requirements

Electrical Input

• Voltage: 115 volts
• Phase: Single phase
• Frequency: 60 Hz
• Amperage: 15 amps
• Standard pneumatics: No compressed air required

The optional pallet-lock roping device requires compressed air. Cousins supplies a filter/regulator and quiet compressor with that option unless the customer provides the necessary air source.

Installation Planning

The three-post frame requires a level floor and appropriate anchoring. Additionally, the site must provide sufficient ceiling height and horizontal clearance for the arm’s complete sweep.

Ameripak should verify:

• Floor condition and anchoring points
• Forklift or pallet-jack approach
• Pallet orientation inside the frame
• Frame and rotary-arm clearances
• Ceiling height
• Pedestrian and vehicle traffic
• Safety-fence placement
• Electrical connection location

Therefore, a layout review before ordering can prevent interference with columns, walls, doors, conveyors or traffic aisles.

How the 4100T-FS3 Wrapping Cycle Works

First, a forklift or pallet jack places the pallet inside the three-post frame. The operator then attaches the film tail and selects the appropriate wrap program. Next, the operator starts the automatic cycle.

Meanwhile, the photo-eye detects load height while the rotary arm travels around the stationary pallet. The powered carriage applies film according to the selected wrap counts, overlap and tension. After the final revolution, the arm decelerates and returns to its aligned stop position. Finally, the operator cuts the film and removes the wrapped pallet.

Best Applications for the FS3 Frame

The 4100T-FS3 works particularly well when a facility wants a self-supporting rotary-arm cell and cannot use a wall-mounted structure.

Typical applications include:

• Heavy industrial components
• Tall or top-heavy pallet loads
• Lightweight products that may shift
• Unstable or irregularly stacked goods
• Fragile products
• Bagged materials
• Building products
• Large containers
• Loads with a high center of gravity

In particular, floor-supported wrapping accommodates loads that exceed the ratings of many turntables. However, the building floor and material-handling equipment must still support the pallet’s total weight safely.

4100T-FS3 Compared with the 4100T-FSR

The FS3 and FSR share the same standard load envelope, rotary-arm speed, powered pre-stretch system and control features. However, their supporting structures create different installation requirements.

The FS3 uses a free-standing three-post frame around the wrapping zone. In contrast, the 4100T-FSR free-standing rear-mount pallet wrapper concentrates its supporting structure toward the rear of the load area.

Therefore, the right choice depends on available floor space, forklift approach, building columns, nearby walls and preferred guarding. Ameripak can compare both official footprint drawings against the intended installation area.

Semi-Automatic or Fully Automatic Rotary Arm?

The 4100T-FS3 requires an operator to position the pallet, attach the film and cut the film after wrapping. Consequently, it offers rotary-arm stability without the cost and complexity of automatic film handling.

Operations requiring conveyors and fully automatic film attachment should consider a system such as the 4100-45-OHA conveyorized automatic pallet wrapper. Ameripak can compare labor requirements, throughput, floor space and integration costs for both approaches.
