Method of manufacturing decorative panels

A method of manufacturing decorative panels, the method comprising:

• feeding a web-substrate along a feeding path in a web-fed inkjet printer;
• printing a decoration layer on said substrate by said printer;
• forming an assembly of layers by applying one or more other layers on said printed substrate and/or applying said printed substrate on one or more other layers;
• pressing said assembly for bounding the layers of said assembly to form a decorative panel;
• and
• during the feeding, controlling tension of said substrate for avoiding one or more wrinkles in said substrate;
• wherein said controlling step is performed by a dancer unit within the feeding path, wherein said dancer unit includes a dancer roll, having
• a shaft which is positioned parallel to a first direction, which is transverse of said fed substrate;
• and
• having a connector on both side ends of said shaft wherein both connectors are connected to a pair of parallel guiders for floating said roll along a floating path which is perpendicular to said first direction;
• and
• wherein the step of controlling comprises:
• moving one guider of said pair of guiders parallel to said floating path for tilting said shaft where said shaft is connected to said moving guider.
