Vérification du grammage des revêtements muraux

Inline measurement and inspection for vinyl, laminate, and wooden flooring

The manufacturing of modern hard flooring, such as Luxury Vinyl Tile (LVT), sheet vinyl, and laminate, involves laminating multiple layers. The quality of the final product depends on the perfection of each layer: the core, the decorative print film, and the protective wear layer. Defects in any of these layers from inconsistent thickness to visual flaws can lead to costly product rejection.

Hammer-IMS delivers non-contact measurement systems that enable manufacturers to control these critical parameters in real time. Our L-Ray, M-Ray, and Edge-Vision systems provide a complete quality assurance solution for high-speed flooring production.

Le processus de fabrication des revêtements muraux à base de papier ou de tissu comprend le revêtement, l'impression et le préencollage. Dans de nombreux cas, le matériau de support est revêtu d'une couleur de fond à l'aide de vinyle coloré (PVC) ou d'une autre substance. Ensuite, des techniques d'impression de motifs peuvent être appliquées, telles que l'impression en surface, héliogravure, sérigraphie ou impression rotative. L'étape finale consiste généralement en une procédure de revêtement humide. Après séchage, le grammage des revêtements muraux finis peut être vérifié à l'aide d'un système de contrôle qualité du grammage Hammer-IMS, qui scanne le matériau dans la direction transversale pour une couverture maximale. Le système peut être équipé d'un ou plusieurs capteurs. En plus de l'inspection du grammage, les revêtements muraux font l'objet d'un contrôle qualité visuel.

Total thickness with L-Ray

The final thickness and flatness of a plank or sheet are critical for easy installation and a perfect finish. The L-Ray laser system provides precise, non-contact thickness measurements.

  • Final product inspection: Installed at the end of the line, the L-Ray measures the total thickness of the finished plank or sheet.
  • Core board profiling: Can be used earlier in the process to measure the thickness profile of core materials, such as HDF for laminate or WPC/SPC cores for vinyl, detecting variations.

Detecting Surface & Print Defects 
with Edge-Vision-4.0

The visual appeal of vinyl and laminate flooring is paramount. The Edge-Vision-4.0 system scans the decorative surface at high speed to ensure it is flawless before the final protective layers are applied or before cutting.

  • Print defect detection: Identifies any errors in the decorative print layer, such as streaks, spots, color misalignments, or missing ink.
  • Surface integrity: Detects physical flaws on the surface, including holes, scratches, dents, or contamination.
  • Reduce waste: It identifies defects immediately, allowing operators to correct the issue or flag the material for rejection before further value is added, such as cutting and packaging.
