In packaging automation, the true test of a system is not just how fast it runs, but how accurately it counts. When you are packing 50 thin sheets of product into a single carton, a counting error of just one sheet means either giving away free product or shortchanging a customer. When done manually, counting 50 sheets is tedious, highly prone to human error, and creates a severe bottleneck that drives up labor costs.
Recently, a Polish manufacturer of furniture accessories approached us with exactly this problem. They needed to automatically count and pack self-adhesive furniture stickers into cartons at high speed.
We provided them with an Automatic Cartoning Machine integrated with a Dual Friction Feeder system. By creatively splitting the feeding task across two synchronized feeders, the customer achieved exactly 50 sheets per box with perfect accuracy, high speed, and a massive reduction in manual labor. Today, based on the success of the first line, they are already planning the procurement of their second system.
Here is how we designed the solution and why the "dual-feeder" approach was the key to their success.
Customer Background:
Location: Poland
Industry: Furniture Auxiliary Materials & Accessories
Main Products: Self-adhesive edge banding stickers, screw hole covers, silicone bumper pads, felt pads, edge banding strips, and laminates.
Packaging Format: 50 sheets of product packed into one carton.
The Pain Points:
In the furniture accessories market, products like screw hole covers and felt pads are often sold in multi-sheet packs. For this customer, the standard retail format was 50 sheets per box.
Before automation, achieving this format manually was a production nightmare.
Counting Errors: Human operators lose track when counting 50 thin sheets hundreds of times a day. Weighing the sheets is also unreliable because the individual sheets are too light and variations in glue/paper weight cause inaccurate readouts.
Slow Cartoning: After counting, manually opening a carton, inserting 50 sheets, and folding the flaps is a slow process that requires a large labor force to meet output demands.
High Labor Costs: In Europe, relying on a large team of manual packers to perform repetitive counting and boxing severely impacts profit margins.
The customer needed a turnkey solution that could count flawlessly, load automatically, and seal the cartons continuously.
To solve this, we did not just supply a standard cartoning machine. We engineered a complete counting and cartoning workflow tailored to their specific 50-sheet requirement.
We anchored the line with our continuous-motion Automatic Cartoning Machine. This machine automatically erects the flat carton blanks, holds them open, pushes the stacked product inside, and folds/tucks the end flaps to seal the box. It eliminates the need for any manual box handling.
The most critical part of this project was the feeding and counting mechanism.
A single friction feeder can easily count 50 sheets. However, dispensing 50 sheets consecutively from one feeder takes a specific amount of time. If the cartoning machine is running at high speed, waiting for one feeder to count to 50 can become the speed limit of the entire line.
Our solution was to integrate TWO Servo Friction Feeders positioned in sequence over the conveyor.
Feeder #1 accurately counts and drops exactly 25 sheets into the conveyor bucket.
Feeder #2 immediately follows, counting and dropping another 25 sheets precisely on top of the first stack.
25 + 25 = exactly 50 sheets.
By splitting the workload, the feeding time per cycle is cut in half. The dual-feeder system easily keeps pace with the high-speed continuous motion of the automatic cartoning machine, maximizing the total output of the line without sacrificing counting accuracy.
After installing and running the equipment in their Polish facility, the results fundamentally changed their packaging economics:
100% Counting Accuracy: The customer reported that the friction feeders' high-precision sensors deliver exact counts every single time. There are no more 49-sheet or 51-sheet boxes.
High Cartoning Efficiency: The synchronized 25+25 feeding logic perfectly matches the cartoner's speed, allowing the line to run continuously without bottlenecking at the counting stage.
Drastic Labor Reduction: The line replaced the entire team previously dedicated to manual counting and boxing. Operators are now only required to replenish the raw materials (loading sheet stacks into the feeders and flat cartons into the magazine).
The Ultimate Validation: The customer is so satisfied with the stability, speed, and labor savings of the first line that they are currently in the planning stages to purchase their second identical line from Jewshin.
This Polish customer case highlights a critical lesson for manufacturers dealing with flat, sheet-like products (stickers, manuals, cards, pads, masks): Integration is where the real value lies.
A friction feeder is a great machine. A cartoning machine is a great machine. But the true production value was unlocked by combining them with a smart dual-feeding logic (25+25) tailored specifically to the customer's 50-sheet requirement. This is the difference between buying standard equipment and investing in a production-oriented solution.
If your factory produces furniture accessories, stationery, cosmetics, or any flat products that require precise counting and automatic cartoning, manual labor is no longer your only option.
Whether you need to pack 5 sheets, 50 sheets, or 100 sheets per box, our team at Jewshin can design a synchronized Friction Feeder and Automatic Cartoning line that perfectly matches your target speed and accuracy requirements.
