The contact-bar concept resolves flute crushing and warping issues.

By eliminating the conventional rider roll, the Isowa Glue Machines solved a lot of old problems. We offer three different models to suit your specific production needs.

| Unlike the rider roll, the contact bar only applies a small amount of pressure. No gap controlling is necessary between the glue roll and the contact bar | ![]() |
Sheet strength is increased, making it less likely for flutes to be crushed. |
|---|---|---|
| Since flute crushing is greatly reduced, only the proper amount of glue is applied to the flute tip, resulting in good, consistent pressure lines. | ![]() |
Sheet warping is reduced. |
| Equipped with independent drive. | ![]() |
The Glue Roll speed is automatically controlled based on web combination. |
| Automatic glue gap correction is standard equipment. | ![]() |
The best glue gap is always selected for the sheet combination and production speed. |
