What a manual brake does

A manual brake folds sheet metal along a straight line: the sheet is clamped, then a hinged bending leaf is lifted by hand to fold the free edge up to the angle wanted.

AFS forms its production profiles on AFS's Thalmann folder, fed from FlashDraft; a hand brake puts every one of those motions in the operator's hands.

Clamping leaf
The upper beam that holds the sheet down on the bed; its front edge, the nose or the fingers, is what the sheet bends against.
Bending leaf

Setback
In Baileigh's words, the distance from the front edge of the finger to the front edge of the bending wing block, on the bending leaf.
Point of operation
In OSHA's words, the area of a machine where work is actually performed upon the material.
Box and pan brake
A brake whose clamping nose is made of movable fingers, chosen to match the box or pan being formed.
