Four-link slotting machine – slot and corner cutting for corrugated boxes

The four-link slotter cuts slots and corners in corrugated box blanks with knives that move up and down. The operator positions the blank and the machine cuts all the slots at once at the set knife spacing.

It is a simple, robust, low-cost machine, suited to small orders, large-format boxes and non-standard box sizes.

Machine overview

The machine uses a mechanical four-shaft linkage to drive the slotting and corner-cutting knife units. Knife spacing is set by hand or by lead screw to suit the box size.
