Top European Printing house ensures the roll quality by ACA RoQ

Highlights of the case

  • Eliminate problematic rolls from the supply chain > Higher production rate
  • 100 k€ annual saving, ROI 2 months > Cost savings
  • Better co-operation with roll suppliers > Higher quality

 

Roll quality of Helio Charleroi ensured by ACA RoQ

Helio Charleroi is one of the most modern printing plants in Europe, serving large and medium volumes publishers and retailers in rotogravure printing. It operates with two state-of-the-art 4,32 meter presses and in total five rotogravure machines with 125 personnel in 24 hours a day and 7 days a week. No wonder, quality control is a key element to achieve high operational rate and meet the tight schedules of demanding customers.

There is no time to solve production issues or struggle with roll defects. ACA RoQ Roll quality analyzer was taken into test phase in March 2017. The goal of the project was to preventively investigate the roll quality before it can cause production downtime or complaints towards suppliers.

 

“We have calculated to save 100k€ annually by eliminating defected rolls before they cause runnability issues in the printing machine. For example we can see baggy rolls in advance. ACA RoQ roll quality analyzer is an amazing innovation that every roll buyer or manufacturer should have”

P. Tornianen, CEO

ACA RoQ – Roll Hardness Profiler ensures quality

 

Core benefits of ACA RoQ

  • Distance measurement with 1 mm accuracy: Profiles are true high resolution hardness profiles including exact position information. Not just single measurement points one after the other.
  • Exact profile data can be used for paper machine controls: For example calendering control.
  • Fast measurement: Measurement frequency even 50 measurements/second. One customer roll measurement can be completed easily less than 30 seconds with high resolution. Wide parent reels less than a minute.
  • Integrated barcode reader: Roll identification easy. Just read the barcode of the roll before the measurement and information is attached to the data.
  • Operator independent measurement: Mechanism guides the hammer always perpendicular against the roll giving excellent repeatability of the measurement.
  • Semi-automated measurement cycle: Operator just place the device against the roll and measurement starts automatically and ends automatically in the end of the profile.
  • Measurement covers full roll length: Also first and last centimetre of the roll is included in the measured profile.
  • Hit force control: Measurement force is generated electrically without spring. This allows excellent control of the hit force and enables simple and accurate calibration of the device.
  • Integrated touch screen display: Simple and user friendly operating. High resolution profile graph displayed right after the measurement.
  • Excellent durability: Basically no wearing parts at all. Only polyamide measurement spoon under the hammer must be changed time to time. Typical lifetime 6 months or more.
  • Low need of maintenance: Calibration and maintenance check recommended once a year.
  • Cloud service available: Data can be transferred automatically from the device to the cloud service provided by ACA.
  • Long operating time: Strong Li-ion battery enables long operating time. More than 2 hours continuous measurement. Charging with USB charger.at
  • Full comprehensive warranty including mechanical parts (excl. wearing parts i.e. measurement spoon)
  • ACA Services available for troubleshooting and maintenance

 

ACA Systems Oy delivers 7th Permi On-line Air Permeability Analyzer for Mudanjiang Hengfeng Paper

Mudanjiang Hengfeng Paper is a paper & forest products company based out of Mudanjiang, China. They manufacture with modern production lines specialty papers including cigarette papers, plug wrap papers, aluminum foil backing papers, tipping base papers, Bible papers, and various types of industrial specialty papers.

In all of their paper grades, the structural uniformity and even porosity is the key for high quality, production efficiency and customer satisfaction.

“We ordered our first ACA Permi in year 2004 as we wanted to find the best and most reliable on-line porosity analyzer to control better our process and quality. We have been extremely pleased with the fast and continuous measurement of the Permi as it helps us to adjust the process in real time. The technology has been further advanced during the years and now, in year 2018, we have been happy to order our 7th Permi from ACA Systems Oy.”

Benefits of on-line porosity control in cigarette paper

  • The porosity has an influence on the temperature of combustion of cigarette papers, which has an effect on the tar level of a cigarette.
  • The porosity has an influence on the taste of cigarettes, on dust content and on temperature of the burning process. Air must also pass the walls of the paper to dilute and cool the smoke of a cigarette.
  • Easy and fast on-line measurements help to keep the porosity of cigarette paper on the correct level and save time and money in grade changes.
  • The biggest problem is to keep the small scale variation as low as possible.
  • The most used measuring standard is Coresta. The usual air permeance of cigarette paper is 30 – 50 Coresta (about 25 – 15 Gurley seconds). With Permi on-line porosity control it is possible to keep air permeance in the desired level.

ACA Systems Oy wins the Excellent Paper Award at Specialty Paper Conference in China

Great news! China Specialty Paper Conference was held this year in Quzhou City on 16th October. ACA Systems won the award of Excellent Paper with the article “The application of hardness tester ACA RoQ in the paper industry” written by Jeff Qian, Sales Manager China.

 

Abstract:

The hardness of a paper roll is closely related to slittering, packing, printing, transportation as well as downstream processes. For a long time, domestic engineers estimated the hardness by visual inspection and hand feeling. This would mislead the adjustments for the related process. ACA RoQ is a new innovation that can measure the paper roll hardness accurately and provides reliable data for correcponding adjustments of the manufacturing or converting processes.

Key words: Paper roll hardness, RoQ, Winding, Caliper Control

ACA RoQ – Roll Hardness Profiler

In focus ACA RoQ

It is well known that the roll hardness has a direct link to roll quality in various operations. As we discussed with our roll manufacturing and converting customers, we noticed that there is a real need to improve the state of the art instrumentation for the roll hardness. Actually, what was used by the roll industry, was developed for other industries and so the accuracy and reliability of such technologies were often questioned. Hence, we developed ACA RoQ, not only to fulfill, but to exceed the needs of the roll industry.

Since the launch of ACA RoQ (2014), we have delivered over 120 units and our customers have identified and eliminated thousands of problematic rolls before causing costly rejections by the supply chain.

ACA PERMI PD – Real time process and quality control analyzer for filter media production

Filtration industry is growing fast, driven by mega-trends such as demand for purer air and cleaner water, both being the subject of ever-more stringent legislation. For filter media producers this means higher filtration efficiency at lower pressure drop levels. Same time the basis weight of media is requested to decrease, but the strengths properties increased. Sounds like an interesting equitation!

We at ACA Systems Oy have developed a reliable tool for you to make the production and quality of filter media to meet today’s and tomorrow’s high expectations of the market.

We have introduced a new continuous air flow analyzer that is able to measure either air permeability or pressure drop of a media real-time during the manufacturing process. The on-line method is fast, reliable and accurate and it gives typically over 0,95 correlations to various lab standards. The structural web control by ACA PERMI PD guarantees the stable quality of filtration media.

Please take a look on our application notes, you might find valuable insights to your cases.
