4100T-FSR Free-Standing Rear Mount Semi-Automatic Pallet Wrapper

Semi-Automatic Rotary-Arm Wrapping for Stationary Loads

The 4100T-FSR pallet wrapper keeps the pallet stationary while a powered rotary arm travels around it and applies stretch film. This design makes the machine especially useful for heavy, lightweight, tall or unstable loads that may shift when rotated on a conventional turntable.

Moreover, the free-standing rear-mount structure creates a dedicated wrapping area without requiring an overhead support system. Operators position the pallet within the frame, attach the film and start the automatic wrapping cycle. As a result, the machine improves consistency while retaining the flexibility and lower complexity of semi-automatic operation.

Benefits of the 4100T-FSR Pallet Wrapper

• Stationary load wrapping: The pallet remains on the facility floor throughout the cycle.
• No machine-imposed weight limit: Instead, the facility floor and material-handling equipment determine the practical load capacity.
• Improved load stability: Consequently, heavy, 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.
• Flexible programming: Operators can select multiple wrap patterns, film-force settings and reinforcement levels.
• Simple utility requirements: The standard machine operates on 115-volt electrical service without compressed air.
• Expandable configuration: Finally, safety fencing, extended frames, taller towers and scale packages remain available.

4100T-FSR Pallet Wrapper Specifications

Production and Load Capacity

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

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

Free-Standing Rear-Mount Rotary Arm

The rotary arm travels around the stationary pallet while the film carriage moves vertically. This approach avoids the rotational force that a turntable applies to the load.

• 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.

Because the arm rotates around the pallet, the installation must provide adequate frame clearance and a protected arm-sweep area.

Powered Pre-Stretch Film Delivery

The 4100T-FSR pallet wrapper includes the Cousins Super Rapid Thread II™ 20-inch powered pre-stretch carriage. Its threading system maximizes film contact with the pre-stretch 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 corners.
• Carriage motor: A 1/2 HP AC variable-speed motor controls film output.
• Rapid threading: The special threading device simplifies film-roll changes.
• Safety interlock: Opening the Rapid Thread™ door interrupts carriage power.
• Roller contact: Greater film coverage helps reduce slipping during operation.
• Pre-stretch rollers: Finally, Cousins provides a lifetime warranty on the rollers.

Therefore, the carriage can improve load containment while helping facilities control stretch-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 helps maintain repeatable carriage positioning.

Programmable Wrapping Controls

Wrap-Pattern and Film Controls

The Panasonic PLC provides straightforward control over the semi-automatic wrapping cycle.

• Cycle start: A single button starts or pauses automatic wrapping.
• 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 speeds: Independent raising and lowering settings control overlap.
• Rotary-arm speed: Variable control helps match movement to load stability.
• Reinforcement: Finally, the mid-cycle reinforce function adds film to selected load 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 controls: Off, on and reset functions include a power indicator.
• Emergency stop: A dedicated control stops machine operation.
• Control enclosure: The NEMA 12 panel protects industrial components.
• Electrical components: Finally, non-proprietary UL/CSA-approved parts simplify service and replacement.

Rotary-Arm Safety System

The 4100T-FSR includes an obstruction-sensitive emergency-stop device on the rotary arm. If the arm encounters an unexpected obstruction, the sensor stops rotation to help protect personnel, the load and the equipment.

However, the rotating arm still requires a clearly controlled operating zone. Ameripak should review aisle traffic, forklift movement, pedestrian access and required guarding during layout planning.

Optional side fences and a front sliding gate can create a more clearly defined wrapping cell. Furthermore, an interlock switch can prevent operation when personnel open the optional gate.

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 and includes a filter/regulator and quiet air compressor unless the customer supplies the necessary air source.

Structural Installation

• Frame construction: Structural steel supports industrial operation.
• Mounting stand: An integral steel structure supports wall and floor mounting.
• Lifting access: Front and rear tubes allow forklift handling during placement.
• Machine tower: Structural steel tubing supports the rotary-arm assembly.
• Protective covers: Sheet-metal panels shield internal components.
• Finish: Finally, electrostatic powder coating helps resist corrosion and wear.

Because the structure requires proper placement and anchoring, Ameripak should confirm the floor condition, mounting surface, ceiling clearance and arm-sweep area before installation.

How the 4100T-FSR Wrapping Cycle Works

First, a forklift or pallet jack positions the load inside the rotary-arm frame. The operator then attaches the film tail to the pallet 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 settings. 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 a Stationary Load

The 4100T-FSR performs particularly well when rotating the pallet could reduce stability or create unnecessary risk.

Typical applications include:

• Very heavy industrial components
• Tall or top-heavy pallet loads
• Lightweight products that may shift during rotation
• 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 can accommodate loads that exceed the capacity of many conventional turntables. The facility floor and material-handling equipment, however, must still safely support the pallet’s total weight.

4100T-FSR Compared with a Turntable Wrapper

A turntable wrapper rotates the pallet while the film carriage moves vertically beside it. In contrast, the 4100T-FSR holds the pallet stationary and rotates the wrapping arm.

For stable, consistently stacked pallets, a turntable model such as the 2100-SRT high-profile stretch wrapper may provide a more compact and economical solution. However, the 4100T-FSR offers a clear advantage when load weight or stability makes pallet rotation undesirable.

Semi-Automatic or Fully Automatic Rotary Arm?

The 4100T-FSR requires an operator to position the pallet, attach the film and remove or cut the film after wrapping. Therefore, it provides semi-automatic consistency without the cost and complexity of a fully integrated system.

Operations requiring conveyorized pallet transfer and automatic film handling 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.
