What Is a Friction Feeder? (And How It Works)

What is a friction feeder

A friction feeder is an automatic device that pulls one sheet at a time from the top of a stack and delivers it downstream into a packaging, printing, or collation line. In the card and packaging world it is most often called a card feeder. It replaces manual placement, raising speed and removing human error.

How a friction feeder works

A rotating belt or wheel contacts the bottom of the top sheet with higher friction than the sheet beneath it. The speed difference drags the top sheet forward while a separator or air knife prevents the second sheet from following. A servo motor controls belt speed and a PLC stores recipes per job.

Key components

• Friction belt or wheel — the contact surface that pulls the sheet
• Separator / air knife — stops the second sheet from double-feeding
• Servo motor + PLC + HMI — speed control and recipe storage
• Photoelectric sensors — missing-card, double-feed and position detection
• Outfeed conveyor — hands the sheet to the next machine

What materials can it feed

Friction feeders handle porous, stable substrates from about 0.1 mm to 3 mm: CR80 cards, game cards, gift cards, ID cards, leaflets, instruction sheets, coupons, and labels. Coated or very slick stock may need vacuum assistance.

Friction vs suction: when to choose

Choose friction when the product is rigid, porous, and not scratch-sensitive, and you need the highest speed at the lowest cost. Choose a vacuum (suction) feeder when the product is non-porous, delicate, laminated, or foil — anything friction would fail to grip or would mark.

Typical applications

Friction feeders are used for trading-card and game-card collation, gift-card and loyalty-card insertion, manual/leaflet feeding into cartons, and coupon or label placement on flow wrappers and labeling lines.

How to size a friction feeder

Match the feeder's rated speed to your bottleneck, not your average. If your wrapper runs 200 packs/min, size the feeder above that. Also confirm the card-size range, changeover time, and detection features before you buy.
