Web Spreading Rollers

PARA Company LLC has 25 years of experience with web spreading roller technology. Of the several different styles of web spreaders on the market:

Title Major features
Smooth, continuous sleeve roll Excellent spreading, expensive, higher maintenance.
Expanding slat roller Restricted to slower processes, fabrics, textile industry.
Nip rolls Can be VERY aggressive, no wrap, inexpensive.
Bowed Roll Excellent spreading action and can do lane spreading.
Brush roller Most cost effective, excellent web and lane spreading.
Grooved rubber roll Possible for material to ‘dip’ down between grooves.
Grooved aluminum roll Research reports ineffective unless dead shaft.

the most common are the bowed roll, the nip rollers, and the grooved rubber roller.

A relatively new product on the market is the brush style roller. The brush style roller offers both price and operating advantages you will want to check out. Less expensive than most other technologies the brush style roller will remove wrinkles from your web with a 90 degree wrap angle or less. So they are extremely useful in compact locations. Optional styles are available for lane spreading of slit widths.

The bowed roller is an excellent, aggressive roll to use where you want the web path to remain relatively straight or your space can not accommodate more than a 15 – 30 degree wrap angle. Additionally the bowed roll is a very good roller for lane spreading slit widths.

Of all the types of spreader technologies available the Nip style rollers are the most aggressive. Two pinch rollers grabbing the edges of your web and pulling in opposite direction need only a minor 3-5 degree angle to achieve full spreading action. However your web MUST enter straight in and leave straight out or you will be putting wrinkles into your product. ZERO wrap angle is absolutely required.

HAUG Static Neutralization

Static Control System

Static electricity is caused by the stripping of electrons from one surface to another. With non-conductive materials this charge can become substantial causing sparks that damage processes, products and equipment. Operators also can receive a “jolt” from static buildup and although the “jolt” doesn’t normally cause an injury, the reaction to getting zapped can.

HAUG Static Control Systems manufactures products which actively produce both positive and negative ions. The field emitted from your product’s charge attracts those ions, (positive to negative and negative to positive), in the neutralization process. Please take a look at the video for a demonstration and call us to start the conversation. 763-473-2757
