Akebono Kogyo is patens for rollers which prevent
meanders. The rollers are most suitable for transporting thin sheet
materials such as papers, films, sheet metals, etc. There are two kinds of
rollers; 1) make a pull-force to the sides and 2) make a pull-forces to the
center. The first described roller prevent making creases and the later
prevents meanders.
Rollers which prevents
meanders
When a roll of metal sheets or papers are transferred by rollers, they
normally shift to the side (meanders). Our "Meanderless"
rollers, which have US patens, keep the sheets straight. It does not
mean that our Meanderless rollers correct meandering. However, our
Meanderless rollers prevent the meanders from occurring.
 
Key Benefits
-
Meanderless rollers can be used as a single or combination of several
rollers. (Pinch methods, bridle methods, or others)
-
Meanderless rollers rotate at the axle of curved roller and has one or two
straight lines at the circumference. By changing the position of the
straight line of the circumference, it changes the roller rotate force
towards the peripherals or towards the center. (Used for eliminating
creases or making creases)
-
Meanderless roller is made of rubber. (It can be used not only as
industrial rubber but also as special designed rubber.)
-
Meanderless roller can be used as a driving roller or back tension roller.

Samples of use of Meanderless Rollers
1) Meander Correcting
Equipment
This equipment rotates freely at the center of the holding
column. By using the differences of the circumference of the roller,
rotate forces has a side force towards the center. This force moves
the entire rollers horizontally and corrects the meanders. (this
equipment corrects meanders roughly. If precise corrections
required, a computer-controlled meander correcting equipment is used.)
2) Accumulator
Makes tension even and prevents meanders from occurring.
3) Pinch Rollers
Two Meanderless rollers are used together. The area where two rollers
are attached together, is always a straight line.
