“2 Precious Roles” in R2R
Role No.1
D e t a c h a b l e
T i l i n g R o l l
Detachable Outer Thin Roll with Precise Structure on Surface
Role No.2
Steel belt Suction
(Vacuum) Conveyor
For Film Handling in R2R Continuous Flat Stage
Detachable Tiling Roll
Detachable Outer Thin Roll with Precise Structure on Surface
タイリング・ロール
R2Rのグラビア印刷や熱圧またはUVインプリントに使われ、主な構成は、芯ロール本体に挿入されたニッケル電鋳製の微細なパターンをもつ極薄のロール（円筒）が表層で、芯ロールとの２層構造となっており、よって取替容易な多機能型ロールです。
TILING ROLL Manufacturing Process
Precision cut to tiling
Tiling weld to sleeve cylindrical weld
Thin wall sleeve insertion to finalize a tiling roll
Typical 4 patterns

Background and Conventional Challenges
❶ Roll with Precise Structure Fablicated Directly on surface
Enormous Manufacturing Cost
Time
Work Heavy Load
Ultra Delicate and Precise Surface for Handling
❷ In case roll wrapped with precise structure sheet
Workability Poor & Difficulty Level High
Irreplaceable or each time renewal
Non-Durable due to blade scraping
Tiling Roll
Solution !!
❶ Precise Butt Welding as called “Tiling”
・Precise Cutting and Edge care of Micro Pattern Sheet
・Precise Butt Welding with End to End of Structure Sheet
・Rolling and Polishing for Better Surface of Welding Line
❷ Highly precise control in accuracy & tolerance
・Precise Cutting method
・Special Care for each Edge
・Hi-Dimension Control in Diameter, Straightness & roundness
❸ Detachable Technology to insert and to pull out of core roll
・Controlling Dimensions of Outer Roll Inner Diameter and Core Roll Outer Diameter for inserting for detaching
・Detaching by Air Surfacing Aid with controlling dimensions of Outer Roll’s and Core Roll’s Diameter
Summary：
Features and Solutions
Manufacturing Standard Dimension
・Roll Diameter：Φ100㎜~Φ400㎜
・Outer Roll Thickness：0.1㎜~0.3㎜
・Roll Length:~1,500㎜
Merrits
・Longer-Durability against Blade Scraping on Deformation Welding Line
・Easy Stock of Various Patterns and replacement to maintain in R2R process
・No time and Effort for Detaching with Outer Roll to insert and pull out of Core Roll

Steel belt Suction(Vacuum) Conveyor
Back Ground and Conventional 3 Challenges in Film Handling
Fluttering and Wave
Gap Instability between Inkjet-Head or Line Camera and film face.
Instability in Film Speed and Accuracy of Distance Transferred
Film Tension Unbalance makes Film Speed instability and inaccuracy of Transferring distance.
Deviation and Side Slip
Lateral Deviation in the Width Derection of Film Transferred Causes instability for Printing and Camera Inspection.
フィルムハンドリングはR2Rの急所ですが、フィルムを制して印刷や検査の作業をサポートするのが、スチールベルト吸引コンベヤです。高速で走るフィルムのバタつき、横ずれなどをベルト全面に空いた小さい吸引孔によるバキュームの効果とスチールベルトのフラットステージで連続的にフィルムの高精度搬送を支えます。
Steelbelt Suction Conveyor
Solution !!
3 kinds of controlling for Film handling
❶ Fluttering and Wave
Film fits its face to extremely Flat Continuous Stage by Suction, No more Fluttering and Wave
❷ Film Flow Direction Unbalanced Tension causes Instability of Film Velocity and transferred distance
Ultra accuracy of Steelbelt makes Film Velocity and Transferred Distance both extremely stable and accurate
❸ Film Deviation brings Various Printings and Inspection of Camera inability
Suction Catches Film Face firmly and causes No Deviation
