    • Urethane plastic foam reinforced with glass fibers is provided, the glass fibers being combined with the plastic foam material prior to foaming. The foaming of the plastic material is physically controlled and restrained to achieve particular desired physical characteristics of the final product. By restricting the extent of foaming, and by using particular layers of fibers, high fiber concentration and more dense skin areas can be obtained in the foam; the fibers can also be initially distributed in a manner to increase their concentration near the surfaces of the foam body. Apparatus is provided for producing reinforced foam in a continuous manner and a method is also provided for combining the fiber reinforcement and the foamable plastic material in a manner such that the plastic material is disposed between two layers of the fiber reinforcement to assure proper distribution of the fibers in the foam. In a preferred form, the fibers are initially disposed in the foamable material in a manner to lie generally perpendicular to the primary direction of growth or rise of the foamable material so that the fibers are also generally perpendicular to the resulting elongate cells. The fibers also preferably are of particular lengths and diameters and present in optimum concentrations to achieve maximum reinforcement and strength in the final product.
    • 提供用玻璃纤维增​​强的聚氨酯塑料泡沫,玻璃纤维在发泡之前与塑料泡沫材料组合。 塑料材料的发泡被物理地控制和约束,以达到最终产品的特定期望的物理特性。 通过限制发泡程度,并且通过使用特定的纤维层,可以在泡沫中获得高纤维浓度和更致密的皮肤区域; 纤维也可以最初分布,以增加其在泡沫体表面附近的浓度。 提供了用于以连续方式生产增强泡沫的装置,还提供了一种将纤维增强材料和可发泡塑料材料组合在一起的方式,使得塑料材料设置在两层纤维增强材料之间,以确保适当分布 泡沫中的纤维。 在优选形式中,纤维最初以通常垂直于可发泡材料的生长或升高的主要方向的方式设置在可发泡材料中,使得纤维也大致垂直于所得的细长细胞。 纤维还优选具有特定的长度和直径并且以最佳浓度存在,以在最终产品中实现最大的增强和强度。

    • A pipe blanket is provided for wrapping around and insulating a pipe. The pipe blanket comprises an insulation mat having an outer surface and an inner surface adapted to lie adjacent the pipe when the pipe blanket is wrapped around the pipe. An outer cover of the pipe blanket is coupled to the outer surface of the insulation mat. The insulation mat is configured to enclose a variety of pipes having different sized diameters. The pipe blanket further includes a closure means configured for securing the insulation mat and outer cover about the pipe. The insulation mat further includes a plurality of pleats.
    • 提供了用于包裹管道并使其绝缘的管道毯。 管道毯包括绝缘垫,其具有外表面和内表面,当管毯缠绕在管上时,该内表面适于邻近管道。 管毯的外盖连接到绝缘垫的外表面。 绝缘垫被构造成封闭具有不同尺寸直径的各种管道。 管道毯还包括闭合装置,其构造成用于将绝缘垫和外盖围绕管道固定。 绝缘垫还包括多个褶。
