| 摘要 |
The invention relates to a manufacturing method for a laminated mat of mineral wool, which comprises a first step of making a mineral wool sheet or mat (1), wherein fibers (3) settle substantially lengthwise of the sheet or mat. The sheet or mat is cut for lamellae of a desired width by cutting crosswise relative to a longitudinal direction of the sheet or mat and the lamellae are rotated through 90° about the longitudinal axis thereof and placed side by side for a laminated structure of a desired length, which is topped with a covering material (4) which holds the lamellae together to build a laminated mat. Lamellae (21) are cut from the mineral wool sheet or mat (1) by angle cutting, in which the cut edge of a lamella forms an angle α within the range of 20-70° relative to a longitudinal plane of the sheet or mat. |
