Article: Precision Tension Control in Nonwoven Converting

Excerpt: “To be a leading player in non-wovens, the producer of web fed rolled goods must not only master new production techniques, which include a greater emphasis on satisfying customer quality requirements, there is also a need to master the inconsistencies and irregularities that crop up in the day to day production process. One of the most effective ways is by improving web control through better tension control.

The production of non-woven materials can present unique tension control problems, for instance, the production of kitchen towels, wipes and toilet tissue, some of which may be embossed and/or printed require very low tensions. Low extensibility and tight tolerances has meant that many producers and OEM’s require precision tension control systems that integrate seamlessly with the parent machine control logic, i.e. PLC/PC systems; systems and system components that are highly responsive to changing conditions in the web, and that are able to provide repeatability of results.”

Which is better for Web Applications, a brake or a drive?

Excerpt: The simple answer is in most unwind applications either system will work equally well and the brake system will be significantly less expensive and less complicated.

The only advantage a drive system has over a brake system is:

1. The drive system can maintain more precise tension during the acceleration of the roll. This is very important if you are running large rolls of very delicate materials (such as tissue paper) or materials that are very extensible.

The disadvantage to drive system is:

1. Significantly more expensive. Not only are the individual components as much as 2-3 times more than a brake system, the installation and service usually requires personnel that are very familiar with drive controllers, PLC, etc.”
