| 摘要 |
The invention relates to a composite roller body (2), comprising an outer layer (10), a core layer (20) and an inner layer (30). The core layer (20) is provided radially between the outer layer (10) and the inner layer (30). The core layer (20) comprises elongated bar elements (21) and a continuous core fabric (22). The bar elements have a outer surface (21a), a inner surface (21c) and two side surfaces (21b, 21d), where the length (Do) of the outer surface (21a) is larger than the length (Di) of the inner surface (21c), and where the side surfaces (21b, 21d) of the bar elements (21) are provided in a radial direction. The continuous core fabric (22) is provided in a radial direction between the side surfaces (21b, 21d) of the bar elements (21) and outside the outer surface (21a) of every second bar element (21) and inside the inner surface (21c) of the bar elements (21) being adjacent to the every second bar elements (21). The outer layer (10) comprises an outer fabric (11) wound around the core layer (20). Resin (40) is provided for bonding the outer layer (10), the core layer (20) and the inner layer (30) to each other. |
