High Speed Fanfold Kraft Paper Folding Machine

Name: High Speed Fanfold Kraft Paper Folding Machine
Brand: Emerson Machinery
SKU: EM-PF500B / PF800B

The fastest fanfold line in the range, at 200 m/min

High Speed Fanfold Kraft Paper Folding Machine built by Emerson Machinery

Product Overview

This is the newest design in our folding range, made for producing the kraft paper rolls used by paperEZ and Ranpak style systems. The kraft roll is perforated, folded and stacked into a pile automatically by the machine. It comes in two widths, 470 mm and 780 mm, and it is the fastest folding line we build at 200 m/min on the 500 model and 150 m/min on the 800.

Key Benefits

200 m/min on the 500 model, more than double the 90 m/min of the standard fanfold machine
Two widths from one design, 470 mm and 780 mm, so one platform covers both pack formats
PLC control with a Weinview touch screen, so fold length changes are set rather than rebuilt
Perforation, folding and stacking all happen automatically onto a conveyor

The Machine And What It Produces

High speed fanfold kraft paper folding machine EM-PF500B

Perforated kraft paper being folded and stacked on the conveyor

Fanfold kraft paper stack collected at the machine discharge

Touch screen and control cabinet of the fanfold folding machine

Application Scenarios

Fanfold pack production for void fill dispensers
Consumable supply for paperEZ and Ranpak style packing systems
In-house production of void fill paper for large fulfilment centres
Contract converting of kraft reels into fanfold packs

Who It Is For

Converters supplying fanfold consumables to packaging distributors
Fulfilment operations paying per metre for bought-in fanfold packs
Packaging groups supplying their own branded void fill paper
Existing fanfold producers whose 90 m/min line has become the bottleneck

Problems It Solves

Bought-in fanfold packs are a permanent per-metre cost for every dispenser in service
Slower folding lines cap how much consumable a converter can supply
Changing fold length on a mechanical machine means changing modules by hand
Loose stacks that will not feed cleanly jam the dispenser at the packing bench

Manufacturing And Quality

The machine is built at our workshop in Ruian, Zhejiang. UDEM has issued CE attestations of conformity to Machinery Directive 2006/42/EC for our honeycomb paper making machine, bag making machine and paper folding machine, referencing EN ISO 12100:2010 and EN 60204-1:2018. A demo machine is kept running in the workshop so the build can be shown and installation supported by video call.

Customization

We have engineers who develop new machine functions to customer requirements, and where the current machine cannot meet a requirement we supply a solution instead. Several machines in this range started exactly that way.

Compared With Our Other Machines

Three folding machines cover this category. The standard EM-PF500A runs 470 mm at 90 m/min and weighs 800 KG, the simplest of the three. This high speed version more than doubles that to 200 m/min, adds PLC and touch screen control and an automatic lifting unwind, and comes in a 780 mm width as well. The EM-PF800A with C-fold inline instead feeds two rolls and folds them into a stronger 2-layer paper.

Use Guide

Load the reel on the automatic lifting unwinding system. Set the perforation and folding length on the touch screen, 11 inch being standard; lengths outside the installed module range need a module change. Run at the speed the stock will take, then collect the folded stack from the conveyor and band it for the dispenser.
