20240246318 · 2024-07-25 ·

On-line synchronous registering co-extrusion SPC floor includes a base material layer, a decorative layer, and a wear-resistant layer. The decorative layer is arranged on the base material layer and provides patterns and designs. The wear-resistant layer is arranged on the decorative layer, is a transparent layer or a semi-transparent layer, and is provided with a concave-convex surface. The patterns or designs correspond to the concave-convex surface; the base material layer is composed of an elastic layer, a strength layer, and a stable layer, and shading is pressed on the bottom layer of the stable layer. Two co-extrusion lines are used for simultaneous extrusion to achieve an ABA three-layer effect of an SPC base material layer. A calender matches a synchronous registering system, and the patterns of the decorative layer are formed in a rolling manner.

METHODS FOR MANUFACTURING A DECORATIVE PANEL, AND DECORATIVE PANELS

A method is provided for manufacturing a decorative panel. The panel includes a substrate and a decorative top layer. The substrate is a mineral containing substrate and/or a thermoplastic material containing substrate. The substrate and/or decorative top layer is obtained from a larger material by means of a dividing operation. The panel includes at at least one and preferably at both upper edges of a pair of opposite side edges a lower edge area. The lower edge area is obtained prior to or during said dividing operation. Decorative panels are obtainable through such a method.

METHOD OF MANUFACTURING A BELT MEMBER AND THE BELT MEMBER
20190070809 · 2019-03-07 ·

A tube material is formed by continuously extruding a thermoplastic resin material in the shape of a cylinder that has a thickness of 100 m and a circumferential length of 800 mm. After that, in a polishing process, the tube material is rubbed with a lapping tape of #2000 while being rotated in one direction at a fixed speed, so that circumferential stripes are formed on the outer circumferential surface of the tube material. Then, the circumferential stripes are thermally transferred by pressing the outer circumferential surface of the heated tube material against a mold surface that is finished in the shape of circumferential stripes by a thermal transfer process.
