Series of through-feed Postforming machines from the manufacturer Homag
Machine design
Conventional through-feed process
| Pre-processing zone | Parallel milling of the coating material |
| Glue application zone | Application of all common types of glue (EVA glue, Polyolefins, PUR glue, PVAC wood glue) using electronically controlled nozzles over the entire height of the profile or using a glue roller, for simple profiles |
| Heating zone | Heating of the coating material, pre-drying using individually adjustable heat lamps and air nozzles |
| Deformation zone | Applying of the coating material by means of bending rod and pressing on with individually selectable pressure rollers. |
| Post-processing zone | Flush milling, grooving, buffing, insertion of piping |
Direct Postforming
For direct Postforming, normal, coated wood-based panels without any excess coating material are used. Accordingly, the pre-processing zone is extended by aggregates which expose the coating material.
| Pre-processing zone | Exposing and parallel milling of the coating material |
