Bar coater/ Alilox roll│OSG SYSTEM PRODUCTS., LTD│OSP
D-Bar is the OSG product with high precision and high efficiency based on the solid technology that has supported the world-wide manufacturing for years. We improved the traditional wire-bar (a kind of coating bar which wire wounded around a core bar) that

Features of D-Bar
Feature 1
Free from wire cut or wire displacement.
The bottom of the groove is designed into a wide shape, so the clogging caused by the coating is reduced, and the bar is easier to clean. Long-term and stable coating performance can be expected to achieve.
Feature 2
Less clogging and easy to clean.
The bottom of the groove is designed into a wide shape, so the clogging caused by the coating is reduced, and the bar is easier to clean. Long-term and stable coating performance can be expected to achieve.
Test method: Test with ink. (gravure ink)
Coating, Cleaning, Wiping * 100 times

Feature 3
Excellent coating liquid leveling property.
The bottom of the groove is designed into a wide shape, so the coating leveling(smoothing) is excellent. Coating defects such as streaks and stains would reduce and the coating surface quality would be expected to improve.
Feature 4
a wide variety of groove shapes are available.
A wide variety of groove shapes would help improve the coating surface quality.
S-type
S-type is the standard groove shape of OSG Wireless Bar. The R shape of the top and bottom of the groove is designed to reduce the clogging problem.
K-type
The bottom of the K-type groove is disigned to aim flat as to improve the coating leveling(smoothing). K-type is comparatively often used in the coating condition of high viscosity and large coating weight.
W-type
It is a specification aimed at reducing initial wear by providing a flat part on the top of the groove.
R-Max (RS) type
It is a specification aimed at reducing initial wear by increasing the R at the top of the groove compared to the S type. And also, improving the coated surface by increasing the contact point with the base material.
WP-type (Wide pitch)
It is a specification aimed at leveling the liquid by widening the pitch between the grooves.
NP-type (Narrow pitch)
This specification increases the number of points supported by the groove, such as when the base material is very thin or when tension is not too high.
M-type
Groove shape with a flat part at the top of the groove and R shape at the bottom of the groove.
0° (Ring)
The grooves are not spiral grooves but completely seperated with each other to prevent inclusion from the end of the bar.
Angled (3°～)
By forming an angle, this groove spec. aim to reduce pitch streaks and expect foreign matter to escape faster during application. Even if you use the S type and streaks remain, angle type would reduce and remove streaks.
