    摘要： An apparatus and method uses vacuum restraint, or other pressure differenl, to hold the ends of a sheet specimen to two opposing surfaces, thereby creating a fold in the specimen. As the opposing surfaces cycle along a parallel axis in opposite directions, the fold repeatedly rolls through a specific region of the specimen. The spacing between the opposing surfaces can be adjusted to increase or to decrease the radius of the fold. The velocity of the fold and the number cycles also can be controlled precisely. After repeated movement of the fold, the adhesion of surface treatments, coatings or printing on the specimen substrate begins to break down. Additionally, the integrity of the substrate itself may begin to deteriorate, if it is susceptible to deterioration and to varying degrees depending upon the susceptibility. The extent to which the specimen coating is degraded and substrate integrity reduced is a function of spacing, fold velocity and number of cycles.

    摘要翻译： 一种装置和方法使用真空约束或其他压力差将片材试样的端部保持在两个相对的表面上，从而在试样中产生折痕。 当相对的表面沿着相反方向上的平行轴线循环时，折叠部重复地滚动穿过样本的特定区域。 可以调整相对表面之间的间距以增加或减小折叠的半径。 折叠速度和数字循环也可以精确控制。 在折叠的反复移动之后，表面处理，涂层或印刷在样品基底上的粘附开始分解。 此外，如果基片易于劣化，并且根据敏感性可以变化，则基底本身的完整性可能开始恶化。 样品涂层退化的程度和底物完整性降低是间隔，折叠速度和循环次数的函数。

    摘要： An improved method and apparatus for dry forming adhesive coated wood fibers in an airstream in a particular mold apparatus. The invention includes a particular sequence of steps and related apparatus, and permits the manufacturer of a mat of differing cross-sectional shapes but of uniform density. The invention includes the advantageous steps of final curing of the mat off of the main molding apparatus, thus achieving efficiencies in use.
