7100-65-OHA Pallet Wrapper for High-Speed Conveyorized Wrapping
The 7100-65-OHA pallet wrapper is a fully automatic, conveyorized rotary-arm system designed for demanding production lines. It wraps up to 65 loads per hour while each pallet remains stationary inside the protected wrapping zone. Therefore, the machine can secure unstable, lightweight, tall or top-heavy loads without exposing them to turntable rotation.
Powered conveyors automatically position each pallet, while the rotary arm applies the programmed stretch-film pattern. After wrapping, pneumatic components cut and wipe the film tail. Finally, the exit conveyor clears the wrapping zone so the next pallet can enter.
Benefits of the 7100-65-OHA Pallet Wrapper
- High production capacity: The system processes up to 65 loads per hour.
- Stationary-load wrapping: Because the pallet does not rotate, products remain more stable during wrapping.
- Automatic pallet movement: Powered conveyors index loads into and out of the wrapping zone.
- Automatic film handling: Pneumatic mechanisms clamp, cut and wipe the film without routine operator involvement.
- Powered pre-stretch: The film carriage supports consistent containment while helping control film consumption.

7100-65-OHA High-Speed Rotary-Arm System
The 7100-65-OHA uses a 20-inch-diameter ring-bearing support system and an ANSI #60 direct chain drive. Shock dampeners help manage rapid acceleration and stopping during continuous production.
- Rotary-arm speed: 1–22 RPM
- Arm motor: 1 HP DC variable-speed motor
- Support system: 20-inch-diameter ring bearing
- Drive system: ANSI #60 direct chain drive
- Acceleration: Controlled soft start
- Stopping: Final-revolution deceleration with positive stop alignment
- Protection: Rotary-arm obstruction emergency-stop sensor
Because the film travels around the load, the pallet remains stationary throughout the wrap cycle. As a result, the machine works especially well with loads that might lean, shift or separate on a rotating turntable.
Ameripak’s turntable versus rotary-arm stretch wrapper guide explains the differences between these two wrapping methods.
Powered Pre-Stretch for the 7100-65-OHA Pallet Wrapper
The 7100-65-OHA pallet wrapper includes the Cousins Super Rapid Thread II™ 20-inch powered pre-stretch film carriage. Its threading arrangement correctly positions the film’s cling side toward the load while maintaining substantial film-to-roller contact.
- Pre-stretch capability: Fixed ratios from 33% to 313%
- Ratio adjustment: Sprocket changes match the carriage to the selected film
- Film-delivery motor: 1/2 HP AC variable-speed motor
- Corner compensation: Electronic dynamic dancer control regulates film delivery
- Film threading: Rapid Thread™ design simplifies roll installation
- Safety door: Opening the carriage door automatically interrupts power
- Film contact: Expanded roller contact helps reduce film slippage
- Pre-stretch rollers: Cousins provides a lifetime warranty on the rollers
Consequently, the carriage can improve film yield while applying consistent containment force around corners and irregular load surfaces.
Film-Carriage Elevator
A heavy-duty elevator moves the film carriage vertically as the rotary arm travels around the pallet.
- Elevator motor: 3/4 HP DC variable-speed motor
- Vertical drive: ANSI #50 direct chain drive
- Shock control: Dampeners help manage acceleration and stopping
- Carriage guidance: Twelve maintenance-free guidance points maintain alignment
- Speed adjustment: Independent raising and lowering controls regulate film overlap
- Braking: Dynamic braking supports repeatable carriage positioning
Moreover, operators can adjust the upward and downward carriage speeds to create the appropriate wrap pattern for each product.
7100-65-OHA Pallet Wrapper Conveyor System
The standard conveyor package includes three powered sections:
- Five-foot powered infeed conveyor
- Twelve-foot powered process and wrapping-zone conveyor
- Five-foot powered exit conveyor
Each section uses chain-driven live rollers and supports loads weighing up to 4,000 pounds.
Conveyor Construction and Performance
- Effective roller width: 54 inches
- Roller diameter: 2-1/2 inches
- Roller construction: 11-gauge steel with 11/16-inch hex axles
- Roller spacing: Three-inch centers
- Roller drive: ANSI #40 chain from roller to roller
- Conveyor speed: 30–60 feet per minute
- Acceleration: Electronic soft start
- Pass-line height: 18 inches above the floor
- Process-conveyor motor: 1 HP AC variable-speed reversible TEFC motor
- Pallet positioning: Photo-eyes and PLC logic automatically index and center each load
In addition, the conveyor system can connect with palletizers, accumulation conveyors and other material-handling equipment. Ameripak can review conveyor elevation, direction of travel and required accumulation when planning the system layout.
Automatic Film Handling on the 7100-65-OHA Pallet Wrapper
The automatic film-handling system eliminates routine manual film attachment and cutting. First, a pneumatically actuated clamp captures the film at the beginning of the cycle. The rotary arm then applies the programmed wrap pattern.
After the final revolution, the arm and carriage return to their finishing positions. Next, a pneumatic cut-and-wipe mechanism moves toward the load. A ni-chrome impulse hot wire cuts the film, and the mechanism wipes the remaining tail against the pallet.
Finally, an automatic cleaning cycle helps maintain dependable hot-wire performance. Therefore, the wrapping zone can prepare for the next pallet without requiring an operator to enter the guarded area.
7100-65-OHA Pallet Wrapper Controls
An Allen-Bradley MicroLogix 1400 PLC coordinates conveyor movement, load positioning and the automatic wrapping sequence. Meanwhile, an HMI touchscreen gives operators access to wrap settings, manual functions and machine status.
Wrapping and Film Controls
- Top wrap count: Adjustable from 1–12 revolutions
- Bottom wrap count: Independently adjustable from 1–12 revolutions
- Film tension: Force-to-load control regulates containment pressure
- Carriage speed: Separate raising and lowering adjustments control overlap
- Load-height sensing: A triple-beam photo-eye detects dark or reflective loads
- Rewrap function: A dedicated button starts an additional wrap cycle
- Bypass mode: Pallets can travel through the system without wrapping
- Film monitoring: Broken-film and out-of-film detection identifies interruptions
- Fault indication: A beacon light communicates machine status
- Ethernet communication: Built-in EtherNet/IP supports system connectivity
Manual and Diagnostic Functions
Operators can manually jog the rotary arm, raise or lower the carriage and open or close the film clamp. Additionally, forward and reverse conveyor controls simplify setup and troubleshooting.
Dynamic braking controls the arm and carriage during stopping. As a result, the components return to consistent finishing positions after each cycle.

How the 7100-65-OHA Pallet Wrapper Works
First, upstream equipment or a forklift places a pallet on the powered infeed conveyor. The conveyor then transfers the load toward the wrapping zone.
Next, photo-eyes and PLC logic index and center the pallet. Once the load reaches the correct position, the pneumatic clamp captures the film and the rotary arm begins its programmed cycle.
Meanwhile, the powered carriage moves vertically to create the selected overlap, top wraps and bottom wraps. After completing the pattern, the arm decelerates and returns to its stopping position.
The pneumatic mechanism then cuts and wipes the film tail. Finally, the exit conveyor removes the wrapped pallet so the system can accept another load.
7100-65-OHA Compared with the 4100-45-OHA
Both machines provide fully automatic, conveyorized rotary-arm wrapping. However, the 7100-65-OHA supports higher production rates and larger loads.
The 7100-65-OHA handles up to 65 loads per hour, accepts loads up to 56 × 56 inches and operates at up to 22 RPM. In contrast, the 4100-45-OHA pallet wrapper handles up to 45 loads per hour, accepts loads up to 50 × 50 inches and operates at up to 20 RPM.
Additionally, the 7100-65-OHA uses a 12-foot process conveyor, a 1 HP rotary-arm motor and a 3/4 HP carriage-elevator motor. Therefore, it fits higher-volume operations that require faster pallet movement and more robust drive components.
