ABSTRACT:
A device for measuring a bending angle of a bent sheet material including a bending angle detector including first and second links arranged symmetrically relative to each other and pivotally connected with each other at one end thereof, a support mechanism for supporting the angle detector on a displaceable ram of the sheet bending press and for displacing the angle detector into an angular space defined by the bending angle of the bent sheet material, and a mechanism for biasing the first and second links into a surface contact with side surfaces of the bent sheet material defining the bending angle.
