Meet Daan van den Heuvel

Daan van den Heuvel

Daan van den Heuvel has been with us for a year and since the 1st of June he has been officially added to our team of Field Service Engineers. Below he briefly introduces himself.

“My name is Daan, 29 years old and I have about 7 years of work experience as a maintenance technician. Before that I was a service engineer for paper machines and I installed production lines for the tobacco industry.

What I particularly like about working at DG press is the diversity of customers and machines, and of course the traveling. What I noticed from day 1 at DG press is the involvement in the work and especially for the customers; when a customer ask a question, the people of DG press will answer it or try to find the answer.

In my spare time I am always busy with sports, food or friends and family. I regularly do Crossfit, I like snowboarding and wakeboarding, and if there is still time I like climbing. I love to cook for friends and family and enjoy the meal together with them.

Last but not least, I am very enthusiastic and curious about what I will learn and experience at DG press.”

How to solve register problems on your Vision or VSOP®

Every Vision and VSOP® web offset press can reach a maximum of 100kg web tension. When this cannot be reached, the rough infeed roll and / or outfeed roll may have become too smooth. This may cause register problems and the worn infeed and outfeed pull rollers must be replaced.

Smooth pull rollers can cause:

  • Registry problems: the automatic register system has problems finding register
  • Irregular web tension
  • Color differences due to register shift
  • More waste because it takes longer to color and register
  • Duplication due to slip of the pull rollers
  • The length of the product does not match the diameter of the pressure cylinder
  • Inaccuracy in post-processing such as pin feed, hole punch and sheet cutter due to slip from the web

What to do when your infeed and / or outfeed roll have become smooth?

Contact us if you have noticed that your rollers become smooth. Our people are happy to think along with you to prevent further problems.

Test your machine

Below is explained how you can check if your machine can reach the maximum of 100kg web tension. Our advice is to test it with a web of approximately 80 grams paper.

02. Buttons and input field to set the lead of the pull roller in the infeed unit.

= More lead

= Less lead

Speed control

In speed control, the leads of each pull roller are changed to reach the desired web tension and web length. The leads change the nominal rotational speeds of the pull rollers, and thus web length.

More lead = Web is extended = Less web tension
Less lead = Web is shortened = Higher web tension

Infeed unit structure

01. Pull roller
02. Pressure roller
03. Web edge control (optional)
04. Web cleaner (optional)
05. Trimming device (optional)
06. Decurling device (only for machines with a sheeter)
07. Insetter controller (optional)
