Overview

A tape head contains several key components that work together to apply, cut, and control tape on each carton. Understanding the name and function of each part will help you troubleshoot problems and perform maintenance correctly.

Tape Head Components

The diagram above shows a typical BestPack tape head assembly. Below is a description of each labeled component:

Component Descriptions

Mandrel

The horizontal shaft that holds and rotates the tape roll. The mandrel supports the tape spool and allows it to unwind smoothly. A tension washer at one end keeps the roll from slipping during cutting.

Optimizing Arm

The curved arm that guides the tape from the roll and helps it stay flat and straight. It prevents tape from bunching or twisting as it unwinds.

Knurled Roller

A textured metal roller that grips and moves the tape downward during application. The knurled (dimpled) surface provides traction to hold the tape without slipping.

Main Spring

The coil spring that applies pressure to the tape head arm, pressing the blade and rollers against the tape and carton with consistent force. Spring tension controls how hard the blade cuts and how firmly the tape is held.

Blade / Blade Guard

The sharp cutting edge that severs the tape after it is applied to the carton. The blade guard protects the blade from damage and prevents accidental cuts. The blade must be kept clean and sharp for proper cutting.

Related Components (Not Shown)

Tape Erect Plate

A hinged plate that guides tape upright and snaps back after each carton to ensure the next box gets tape. It works with a spring to reset position.

Front Application Roller with Clutch

A one-way clutch mechanism that applies tape to the front of the carton. The clutch grips the tape in one direction (forward) but cannot hold it backward, preventing tape from bunching.

Rear Roller Arm

A spring-loaded arm that holds the rear edge of the carton and supports the tape as it is cut and wiped clean.

Maintenance Tips

• Refer to the TapeHead Preventive Maintenance checklist for a complete maintenance schedule.
• Keep all pivot points and roller shafts lightly oiled (not dripping).
• Replace blades before they become dull—a sharp blade is safer and cuts better.
• Check springs monthly. A weak spring will cause tape or cutting problems.
