ACTION 14

Stripping

Cutting or peeling a joining material or strand away from its target

Why It Matters

Cutting and peeling are where opening and disassembly begin. Examples include opening sealed boxes, removing shrink film, cutting cable ties, and removing labels from reusable containers.

Dedicated box openers are limited to lines with uniform specifications and seal patterns. When bond strength and seal form differ case by case, an entry point for the blade must first be created through contact.

14-ATape Seal CuttingTOOL

The position of the contents cannot be observed, yet the cutting depth must be adjusted to avoid damaging them.

Tape Seal Cutting — Initial state
Initial stateA container closed with sealing material is in place, and a tool is held in hand.
Tape Seal Cutting — Final state
Final stateThe seal is opened without damage to the contents.

14-BBare-Hand Film Removal

An entry point must be created without a tool, and the force available at the fingertips must exceed the material's tensile strength.

Bare-Hand Film Removal — Initial state
Initial statePackaging material clings to an item, and no tool is available.
Bare-Hand Film Removal — Final state
Final stateThe packaging material is removed from the item.

14-CCable Tie CuttingTOOL

The tie sits flush against the object, leaving no gap for entry, and the cutting force is not known in advance, so the force must be controlled right after the blade breaks through.

Cable Tie Cutting — Initial state
Initial stateBinding material sits flush against an item, and a tool is held in hand.
Cable Tie Cutting — Final state
Final stateThe binding is released without damage to the item.

14-DAdhesive Label Peeling

The entire adhesive face is bonded, leaving no starting point for peeling, and the applied force and angle can damage the object.

Adhesive Label Peeling — Initial state
Initial stateAn adhesive element is bonded to an item across its entire face.
Adhesive Label Peeling — Final state
Final stateThe adhesive element is removed without damage to the item.

14-EWire CuttingTOOL

The workpiece is not fixed in place, so tension must be created directly, and a reaction force remains right after cutting.

Wire Cutting — Initial state
Initial stateAn unsecured linear object lies in place, and a tool is held in hand.
Wire Cutting — Final state
Final stateThe object is cut at the specified point, and no cut piece has flown off.

14-FPerforation Tearing

Tension must be applied along the perforation for it to separate, and the slightest deviation in direction sends the tear off the line.

Perforation Tearing — Initial state
Initial stateA sheet-like object joined along a perforation has not been separated.
Perforation Tearing — Final state
Final stateThe object is separated along the perforation, and the tear stays on the line.

14-GFitted Cover Removal

The flexible cover is fitted tightly to the object, so the force used to remove it drags the object along.

Fitted Cover Removal — Initial state
Initial stateA flexible cover is fitted tightly over an item.
Fitted Cover Removal — Final state
Final stateThe cover is removed without moving the item.
