Honeycomb Paper Machine

Product Overview

The EM-PH800 is built around a customer requirement for filter media rather than packaging. It die cuts flame resistant or flame retardant kraft paper up to 700 mm wide and rewinds it into a roll that is used as filter material. The frame is deliberately longer between the die cutting module and the rewinder so that a stitching or sewing machine can be added into the process. The same machine still runs plain honeycomb and mesh paper for packaging work.

Key Benefits

  • One frame covers two jobs: honeycomb packaging paper and flame resistant filter media
  • Extended span between die cutting and rewinding leaves room for the customer's own stitching or sewing unit
  • Rewinding diameter goes to 600 mm on flame retardant paper, against 300 mm on standard grades
  • 700 mm working width suits filter element blanks that are wider than packaging wrap
Problems It Solves

What This Machine Fixes

  • Standard kraft is not flame resistant, which rules it out where an open flame or high temperature is present
  • Separate machines for packaging paper and filter media tie up floor space and capital
  • Retrofitting a stitching station to a compact converting line is usually impossible
Who It Is For

Who Buys It

  • Filter element manufacturers who currently buy die cut media
  • Converters serving construction, electrical insulation and packaging with one asset
  • Paper converters looking for a second market beyond protective packaging
Application Scenarios

Where The Output Is Used

  • Producing filter material rolls for workshop and industrial air filtration
  • Making flame resistant media where fire safety governs the specification
  • Running standard honeycomb and mesh kraft when the filter order book is quiet
  • Supplying die cut media to filter element assemblers

Manufacturing Process

The Process This Machine Runs

Unwinding

Stage 1 of the flame resistant filter paper making machine process.

Honeycomb die cutting

Stage 2 of the flame resistant filter paper making machine process.

Optional inline stitching or sewing

Stage 3 of the flame resistant filter paper making machine process.

Rewinding

Stage 4 of the flame resistant filter paper making machine process.

Quality Control

  • Die cut pattern checked across the full 700 mm width before the run
  • Rewind tension set for the larger 600 mm flame retardant roll diameter
  • Machine test run at the factory on the customer's own paper where a sample is supplied

Use Guide

  • Confirm the paper grade is genuinely flame resistant before setting rewind diameter to 600 mm
  • Run the die cutting module at reduced speed on the first metres of a new grade
  • Leave the stitching station accessible for thread changes when laying out the line
  • Record the working speed that gives a clean cut on each paper grade you run
Comparison

How It Compares With The Alternatives

Compared with Kraft Honeycomb Paper Forming Machine EM-PH600

The EM-PH600 is a 515 mm packaging machine running to 200 m per minute. The EM-PH800 trades speed for a 700 mm width and the space to stitch filter media inline.

Compared with Buying die cut filter media

Producing media in house removes the converter's lead time from the filter assembly schedule.

Answers

Flame Resistant Filter Paper Making Machine FAQ

Can this machine make ordinary honeycomb packaging paper as well?

Yes. Run without the pulling and cutting stage and the finished paper rewinds directly onto the air shaft as honeycomb or mesh kraft for packaging.

Why is the rewinding diameter different for flame retardant paper?

Standard rewinding diameter is zero to 300 mm. For flame retardant paper the machine is built to rewind up to 600 mm.

Can we add our own stitching machine?

Yes. The gap between the die cutting module and the rewinding device is lengthened for exactly that, so a stitching or sewing machine can be fitted into the process.

What is the maximum working width?

700 mm material width, with unwinding up to 1200 mm diameter and a 1 tonne roll.

How fast does it run?

Zero to 100 m per minute, adjustable.

What does the machine weigh?

1800 kg, with overall dimensions of 3200 x 1350 x 1300 mm.
