UE Wrinkle Removing Roll

ダウンロード

Remove wrinkles from all web materials,
Enable you to greatly improve its quality and productivity.
We are the reliable partner for “Spreading”.

The no-bow and linear roll can realize naturally removing wrinkles without web distortions.

If it is called a wrinkles picking roll, a bow roll (an bow roll, a banana form roll, a curve roll) is common. However, therefore, the form will lengthen the central portion of a web too much than other portions, and the bow roll had a structural defect “it is superfluously extended in the central part and slackens near the edge” It is UE wrinkles picking roll which was developed in order to solve this problem. The rubber of a roll surface stretches greatly gradually toward both sides from a center. The growth of this rubber has the same effect as turning a web outside, lengthening it from a center, by hand, and eliminating wrinkles. For this reason, the full width of a web can be expanded gently and wrinkles can be removed. In addition, a wrinkles picking roll has two forms of elastic cord type “a flat expander (FE)” and rubber tube type “Miravo (MRV).” We have dimensions to specifications of a film and the Web using, rubber materials. We have dimensions to specifications of a film and the Web of the errand, rubber materials each.、Furthermore, I am planning substantial lineup that it should answer to needs.

※”UE” is an initial of U-Engineering industrial incorporated company which developed this product group.  Although business transfer of the “Wrinkles picking roll” was received in 2005, we are making this initial  into the brand name of our company.

Flat Expander Roll
FE-B Series 

UE_Flat-Expander.jpg
FE-BB

 

  • A flat expander (FE) is a wrinkles picking roll of the shape of an elastic cord type straight line.
  • Wrinkles, such as cloth, a nonwoven fabric, a plastic film, paper, and glass fiber, can be removed. 
  • On the roll perimeter, many elastic cords are stationed equally. Whenever a roll rotates, each elastic cord repeats elasticity. A web is dewrincled by an elastic cord's growth, if a web is winded while becoming the maximum from the position where an elastic cord begins to be extended. Thereby, wrinkles are removed from a web.
  • It is a high-class roll using the parts refined highly. For example, a resin piece for extremely low runs of the coefficient of friction is attached to the undersurface of the elastic cord. Thereby, an elastic cord can be extended progressively, without checking the growth.

Miravo Roll
MRV Series

MRV-8

  

  • Miravo roll (MRV) is a wrinkles picking roll of the shape of a straight line covered with the rubber tube.
  • Wrinkles can be removed from a nonwoven fabric, a plastic film, paper, glass fiber, metallic foil, etc. 
  • The rubber tube covered to the roll perimeter side expands and contracts with roll rotation by a special internal structure. A web is dewrincled by an elastic cord's growth, if a web is winded while becoming the maximum from the position where a rubber tube begins to be extended Thereby, wrinkles are removed from a web.
