Crease Bending Force Tester for Folding Cartons

Measures the force needed to fold a creased board specimen through a set angle, indicating crease quality and fold-back tendency. Used by folding carton and mono carton converters when setting up creasing rules and matrices.

Specification

Creased test strips are clamped so the crease line sits on the bending axis, and a load cell records the resisting force as the arm folds the specimen. Comparing machine and cross direction values shows whether the creasing depth and matrix width are right. Data helps reduce cracking on the fold and poor box erection on automated lines.

Features

• Load cell measurement with peak and average force
• Programmable bending angle 0-90 deg
• Motorised bend arm with constant angular speed
• Specimen clamp with crease line alignment guide
• Result storage and mean calculation for sample sets
