摘要： An insulating fiber mat is comprised of a plurality of fibers bound together by a binder means and distributed throughout the mat. At least some of the fibers throughout the mat are inclined. The inclined fibers on opposed sides of a central horizontal plane of the mat have opposed angles of inclination. This permits the fiber mat to be easily separated substantially along the central horizontal plane by applying a pulling force on one side of the mat in the direction of the inclined fibers.

摘要： A fiber mat as well as its method of fabrication and forming machine are described. The fiber mat comprises a plurality of fibers which are limitations bound together and distributed throughout the mat, and wherein some of the fibers are inclined towards a central horizontal plane of the mat. The inclined fibers on opposed sides of the mat have opposed angles of inclination whereby the mat, when used as insulation, can be easily separated substantially along the central horizontal plane by applying a pulling force on one side or opposed sides of the mat in the direction of the inclined fibers. The forming machine is characterized by having two forming surfaces, one disposed horizontally and the other vertically whereby the mat is formed with higher density towards the opposed flat horizontal surfaces of the mat and the lower density is distributed along the central horizontal plane. By having these opposed forming surfaces there is provided a former which provides double formation capacity capable of providing a mat with improved density profile, provides higher air flow, less shingling effect, and the production of a mat which can be easily split substantially in the middle along the central horizontal plane when used as an insulating mat. Because the former doubles the capacity of fibers and also the thickness of the formed mat, it is possible to compress the mat to form fiber boards.
摘要翻译： 描述了纤维毡及其制造和成型机的方法。 纤维垫包括多个纤维，其是限制在一起并分布在整个垫子中的限制，并且其中一些纤维朝向垫的中心水平面倾斜。 垫子的相对侧上的倾斜纤维具有相反的倾斜角度，当用作绝缘体时，垫可以通过在垫的一侧或相对侧上沿着方向施加拉力而容易地沿着中心水平面分离 的倾斜纤维。 成形机的特征在于具有两个成形表面，一个水平放置，另一个垂直放置，由此垫子朝向垫的相对的平坦水平表面形成较高密度，并且较低密度沿着中心水平面分布。 通过具有这些相对的成形表面，提供了一种提供双层形成能力的成形器，其能够提供具有改进的密度分布的垫，提供更高的气流，更少的搭接效果以及可以容易地在中间大致分裂的垫的生产 当用作绝缘垫时，沿中心水平面。 因为前者使纤维的容量和形成的垫的厚度加倍，所以可以压制垫以形成纤维板。

摘要： An aerodynamic forming hood is provided for supplying a substantially uniform distribution of fibers in a downward laminar airstream for the deposition of the fibers on one or more forming surfaces. The hood is formed by a rectangular housing having opposed elongated downwardly diverging side walls and short downwardly diverging end walls. The housing has a smaller rectangular open top end through which a supply of fibers is released in an airstream which enters into the housing. The forming surfaces are disposed at a larger bottom forming end of the housing. The side walls and end walls in the top part of the hood are provided with elongated horizontal apertures. Controllable suction boxes are connected to the apertures for the controlled evacuation of air and fibers through the slots to substantially eliminate the formation of air turbulence and hence boundary layer separation in the airstream inside the housing to obtain the said laminar airstream with a substantially uniform distribution of fibers therein.
