    • A unitary fibrous structure comprises a plurality of cellulosic fibers randomly distributed throughout the fibrous structure, and a plurality of synthetic fibers distributed throughout the fibrous structure in a non-random repeating pattern. A process for making the unitary fibrous structure comprises the steps of providing an embryonic fibrous web comprising a-plurality of cellulosic fibers randomly distributed throughout the fibrous web and a plurality of synthetic fibers randomly distributed throughout the fibrous web and causing redistribution of at least a portion of the synthetic fibers in the embryonic web to form the unitary fibrous structure in which a substantial portion of the plurality of synthetic fibers is distributed throughout the fibrous structure in a non-random repeating pattern.

    • A collimator, in combination with a source of curing radiation, for use in a process for curing a photosensitive resin disposed on a working surface and having a machine direction and a cross-machine direction perpendicular to said machine direction, is disclosed. The preferred collimator comprises a plurality of mutually parallel collimating elements spaced from one another in the machine direction between the source of radiation and the resin. Each of the collimating elements is substantially perpendicular to the working surface, and every two of the mutually adjacent collimating elements have a machine-directional clearance and a cross-machine-directional clearance therebetween. The collimating elements and the machine direction form an acute angle therebetween such that the machine-directional clearance is greater than the cross-machine directional clearance. This allows to provide a greater collimation of the curing radiation in the cross-machine direction relative to the machine direction. The present invention is related to processes and equipment for making papermaking belts comprising a resinous framework.
    • 公开了一种与固化辐射源组合的准直器,用于固化设置在工作表面上并具有与机器方向垂直的机器方向和横机方向的感光性树脂的工艺。 优选的准直器包括在辐射源和树脂之间沿机器方向彼此间隔开的多个相互平行的准直元件。 每个准直元件基本上垂直于工作表面,并且每两个相互相邻的准直元件具有机器方向的间隙,并且其间具有跨机器方向的间隙。 准直元件和机器方向在其间形成锐角,使得机器方向间隙大于跨机器方向间隙。 这允许相对于机器方向在横跨机器方向上提供更大的固化辐射准直。 本发明涉及用于制造包含树脂框架的造纸带的方法和设备。
