Binding

Wrapping a flexible element around a target and building tension that holds it

Why It Matters

Binding is a finishing step performed before transport and storage. Examples include strapping palletized cargo, tying off wire harness branches, and bundling packages.

Banding and strapping machines work where the object's shape and dimensions are fixed. When the shape varies from item to item, the binding material and the object deform together during tightening, so the stopping point cannot be set in advance.

09-AOversized Object Binding

A suitable tension must be found between the lower limit that prevents loosening and the upper limit that crushes the object, but the object's size keeps the tension from spreading evenly around it.

Oversized Object Binding — Initial state
Initial stateA large load and its binding material are separate.
Oversized Object Binding — Final state
Final stateThe load is bound without damage, and the tension holds.

09-BKnot Tying

A knot is a topological structure in which the cord passes through itself, so the goal cannot be described in coordinates, and releasing tension before completion undoes it.

Knot Tying — Initial state
Initial stateAn item and a cord are separate.
Knot Tying — Final state
Final stateThe cord is wrapped around the item and secured with a knot.

09-CSmall Bundle Binding

Tightening shrinks the bundle's cross-section, changing both its shape and the tension required, and strands can slip out of the bundle in the meantime.

Small Bundle Binding — Initial state
Initial stateSeveral linear objects lie scattered.
Small Bundle Binding — Final state
Final stateThe objects are bound into a single bundle with no strand left out.
