<p>An apparatus for measuring the flexural resistance of ribbed patterns comprises a clamp (1) for clamping a die-cut and ribbed cardboard sheet (2), which clamp is so driven as to cause the ribbed portions of the cardboard sheet to engage against one or more rollers (4) which are coupled to corresponding load cells (5) adapted to measure the force necessary for folding the ribbed portions and display this force on a display.</p> |
