Solves wrinkles and waviness during the transport of films, foils, etc., enabling winding with low tension and low contact pressure! This is a transport rubber roll that can reduce product defects!
The "micro-grooved processing roll" is a transport rubber roll that promotes the discharge of air trapped between the substrate and the roll by applying fine grooves to the surface of the roll, thereby reducing wrinkles and waviness. 【Features】 ◆ Can stretch wrinkles without damaging the substrate ◆ Improved adhesion between the substrate and the roll allows for transport without increasing tension ◆ Selectable groove processing patterns based on the film or desired additional functions 【For more details, please download the catalog or feel free to contact us】 ↓ ↓ ↓ ↓ ↓ ↓

basic information
Rolls with fine groove processing can add the following functions: 1) Wrinkle removal effect In the case of rubber rolls, the synergistic effect of fine groove processing, W helical lead, and inclined grooves allows for wrinkle removal without damaging the substrate. They can be used as a substitute for expander rolls or crown rolls. 2) Increased grip of the roll and air skew effect The issue of substrate lift due to air entrapment, which prevents increasing line speed and causes scratches from slipping, can be resolved with fine groove processed rolls. By removing the air that intervenes between the substrate and the roll, the adhesion between them is improved. Therefore, it becomes possible to transport even rolls with a small wrap angle without increasing tension. Additionally, due to the narrow groove width, the substrate is less likely to drop into the groove edges, thus avoiding the occurrence of transfer scratches.
