摘要： A method for fabricating shaped-paper products is introduced herein, which comprises at least one dredging-pulp step for forming a wet pulp made of paper-slurry materials, at least one pre-compression step for lightly compressing the wet pulp to form a first semi-finished product, at least one thermo-compression forming step for deeply compressing the first semi-finished product to form a second semi-finished product, and a surface-coating step of employing a product surface coating apparatus to coat a liquid coating materials onto at least one outer surface of the second semi-finished product, and thereby forming each of the shaped-paper products having a binding layer. With utilization of the present invention, an automatic coating can be applied high efficiently in a series of continuous production machines. This could not only shorten processing time and benefit a mass production thereof but also ensure a higher production yield and quality.

摘要： Partitioning control of the wet end and dry end, by introducing estimates of physical properties such as dry weight: and percent ash at the wire, allows for machine direction (MD) controls to continue during loss of scanner measurements. A mathematical model estimates the controlled, variables, such as dry weight, basis weight, and ash percent at the wire, and these estimated values are then controlled. When scanner measurements resume, parameters in the model are recursively updated to compensate for any model errors and ensure an accurate model. MD controls consist of a cascade set-up where the estimated wire-dry weight or wire basis weight and estimated wire ash percent are controlled by manipulating stock flow and addition of filler to stock. When scanner measurements are available, they become the downstream variables in the cascade control and are controlled by manipulation of the setpoints for the estimated wire weight and ash.

摘要翻译： 对湿端和干端进行分区控制，通过引入物理性质如干重的估算值以及线材灰分百分比，可以在扫描仪测量失败期间继续进行机器方向（MD）控制。 数学模型估计受控的变量，例如干重，基重和电线上的灰分百分数，然后控制这些估计值。 当扫描仪测量恢复时，模型中的参数被递归更新，以补偿任何模型误差并确保准确的模型。 MD控制由级联设置组成，通过操纵库存流量和添加填充料，控制估计的线干重或线材重量和估计的线灰分百分比。 当扫描仪测量可用时，它们将成为级联控制中的下游变量，并通过操作估计的线重和灰分的设定值来控制。

摘要： A non-woven material, that can be formed into an acoustic ceiling tile, is provided. The material includes a substantially planar and self-supporting core of an inorganic base fiber and a synthetic thermal bonding fiber. The synthetic thermal bonding fiber preferably has an increased bonding surface area that improves adhesion and porosity to provide a base mat or core with a low density to provide sound absorption required by an acoustic ceiling tile.
