ABSTRACT:
A score bend testing apparatus consists of a base having an upwardly facing support surface which supports a scored sheet of material. The support defines a forward edge, and the score is positioned forwardly of the forward edge while the rearward portion of the sheet is clamped against the support by a clamping device. A force gauge assembly is moved downwardly to engage the sheet of material forwardly of the score, and downward movement of the force gauge assembly results in the sheet of material being bent at the score. The force gauge assembly determines the amount of force required to bend the sheet of material. The force gauge assembly is mounted to a cross-member which extends between movable output members associated with rodless pneumatic cylinders.
