Web wrinkles are one of the biggest profit eaters for converters. They can cause defects in processes, waste due to unacceptable product, and poor customer satisfaction.
There are many anti-wrinkle solutions on the market. The question is; how can you control or eliminate web wrinkles without breaking the bank? One product consistently shows an excellent balance between performance and cost effectiveness.
Nip type anti-wrinkle devices provide highly aggressive anti-wrinkle performance and are very reasonably priced. Return on investment is typically very fast when the opportunity arises to utilize this anti-wrinkle technology.
Nip type anti-wrinkle systems incorporate small diameter, short face nip rollers, spring loaded in contact with each other. They come in a left and a right hand set and mount on each side of your web. Each of the nip sets are angled away from each other. Utilizing the web handling principal, that a web will seek a 90 degree angle to a roll in its entry span to that roll, they effectively pull on each of the web. Nip type anti-wrinkle devices are probably the most aggressive available. They will remove tons of wrinkles and even stretch your web if so desired. It's easy to adjust how aggressive this system is; simply adjust the angle of each nip set. Originally designed for textiles and non-wovens, this spreading system has been found to work well with papers, films, laminates and coated materials.
A NEW, value added mounting bracket is currently available for use with nip type anti-wrinkle devices. This new mounting bracket is extremely easy to mount with four mounting holes per side. A cantilevered, extruded aluminum slide rail makes for fast, easy web width adjustment. It includes an adjustment knob for easy angle adjustment for each nip set. An angle indicator ensures accurate, repeatable angle adjustment. Angle adjustments, which adjust the amount of anti-wrinkle aggression, can be made while the web is in motion, without the use of tools.
Perhaps the best thing about this type of anti-wrinkle device and mounting bracket is that a trial pair is generally available. If you think this system will work for you but you are not sure, ask for a trial pair to try them out.
