On an automatic die-cutting machine, the feeder decides whether print stays scratch-free and whether heavy corrugated runs stay stable at speed. OUNUO / OYANG Wenhong lines typically offer several feeding architectures so one frame can serve mixed packaging jobs.

Top feeder (four-suction / four-feed style)

Uses multiple suction and feed points to send sheets neatly and continuously into the next station. Ideal for cardboard and thinner stocks when you need precise positioning at high speed for folding cartons and printed paper packaging.

Front-edge feeder

A front roller with high-pressure air and a servo-driven belt advances the sheet. Strong adaptability helps when sheets have light warp — a common reality in humid plants across coastal Asia and Latin America.

Bottom suction feeder

Imported-class vacuum pumps with servo belts lift and feed from below. This path reduces scuffing on heavily printed surfaces and keeps feeding fast and stable for premium graphics packaging.

How to choose for your mix

• Light cardboard / thin paper, high graphic value — prioritize top or bottom suction to protect print.
• Heavy corrugated or warped board — front-edge or bottom suction usually beats a pure top feeder for stability.
• Mixed jobbing plant — ask for multi-feeder options on the same large-format machine.

Share your GSM range, max sheet size and whether sheets arrive pre-printed. OUNUO export engineers will recommend a feeder setup with the die-cutting body for your carton or corrugated program.
