It has end pretending of high precision. It has high accuracy end pre-bending when
bending the end and it can freely set the length of the edge. Top roller presses
down, and high accuracy end pre-bending is done under a certain pressure.

It has NC controlled high producing efficiency with simple operation and high efficiency.
It has different uses with coordinating controlling methods. There are
following controlling methods according to its uses:
TNC: for many types but small quantity of production
T&BAC: for few types but large quantity of production
CNC: for many types but large quantity of production

It has excellent product precision. Products have superior precision due to continuous
bending and high accurate end pre-bending. Products have superior precision,
as the top roller is in the shape of drum. With the supporting roller adjusted,
it can coil ideal products in the wide range from sheets to plates.

It has rich bending shapes. There are such different shapes as O shapes, U shapes
and multi-section shape. The method is as follows:
O bending: back bending mode
U bending: front bending mode
Special bending: composition mode
