    • An apparatus for tensioning, stretching or pulling a traveling web of material (e.g., single or multiple layers) lateral to the longitudinal or machine direction of the traveling web is disclosed. The apparatus includes at least one but usually a pair of clamping devices to be disposed opposite each other on lateral edges of the traveling web upstream of a processing area where the clamping devices include stationary members, where at least one stationary member includes first and second ends and a material-engagement surface, wherein, when in operational position, the first and second ends define a direction of the material-engagement surface that is transverse to the machine direction of the traveling web. A method of stretching or pulling a single layer or multiple layer web of material laterally to the machine direction of the traveling web to remove wrinkles also is disclosed.

    • A system for controlling deflection of a dynamic surface includes at least one sensor in communication with the dynamic surface for detecting the presence of a deflecting force on the dynamic surface and generating a feedback signal proportional to the deflecting force. The system includes a controller in communication with the at least one sensor for receiving the feedback signal and generating an output signal in response to the feedback signal. At least one piezoelectric actuator is in communication with the dynamic surface and in communication with the controller for receiving the output signal and applying a counter deflecting force on the dynamic surface for removing the deflection from the dynamic surface. In other preferred embodiments, the piezoelectric actuators maintain the dynamic surface in a preferred shape, such as a curved surface.
    • 用于控制动态表面的偏转的系统包括与动态表面连通的至少一个传感器,用于检测在动态表面上存在偏转力并产生与偏转力成比例的反馈信号。 该系统包括与至少一个传感器通信的控制器,用于接收反馈信号并响应于反馈信号产生输出信号。 至少一个压电致动器与动态表面连通并与控制器通信,用于接收输出信号,并在动态表面上施加反偏转力以去除动态表面的偏转。 在其它优选实施例中,压电致动器将动态表面保持在优选的形状,例如曲面。

    • A finishing assembly which includes an outside treatment roll for treating both sides of an endless web without having to remove, turn inside out and reload the endless web onto the finishing assembly. The outside treatment roll is movable and adapted to contact the endless web within an opening defined between a pair of cantilever beams such that the "minimum loop length" of the endless web is preserved. The finishing assembly includes a movable non-contacting treatment assembly which is adapted to be arranged between the cantilever beams such that the non-contacting treatment assembly may be used with or without the outside treatment roll to facilitate different finishing processes. In addition, the finishing assembly may include a pivotable cantilever beam in place of one of the cantilever beams. The pivotable cantilever beam may be rotated out of the finishing assembly, further minimizing the "minimum loop length" of the endless web. Finally, one of the cantilever beams may also be movable from a first position to a second position, wherein when in the second position, that beam is not in the way of the endless web and therefore does not interfere with the web. This again provides for a minimizing of the "minimum loop length."
    • 一种精加工组件,其包括用于处理环形纤维网的两侧的外部处理辊,而不必去除,向内转出并将环形纤维网重新加载到精加工组件上。 外部处理辊可移动并且适于在环形腹板之间限定在一对悬臂梁之间的开口中接触环形腹板,从而保留环形腹板的“最小回路长度”。 精加工组件包括可移动的非接触处理组件,其适于布置在悬臂梁之间,使得非接触处理组件可与外处理辊一起使用或不使用,以促进不同的精加工过程。 此外,精加工组件可以包括可摆动的悬臂梁,代替悬臂梁之一。 可旋转的悬臂梁可以旋转出精加工组件,进一步最小化环形腹板的“最小回路长度”。 最后,悬臂梁中的一个也可以从第一位置移动到第二位置,其中当处于第二位置时,该梁不妨碍环形腹板,因此不会干扰腹板。 这再次使“最小环路长度”最小化。

    • A press roll system employed in connection with a web finishing assembly is provided. The press roll system includes a press roll, which cooperates with a head roll to provide a uniform nip area and pressing load; a support substrate, arranged between the ground and the press roll; at least one backup roller mounted to a first surface of the support substrate along a continuous axis for substantially the length of the press roll, and arranged to provide a uniform load to the press roll and uniform area between the press roll and head roll during operation to impart a uniform caliper to the web; and a retractable force actuator, mounted on a second surface of the support substrate, opposite the surface to which the backup rollers are mounted, to provide an even distribution of loads toward the press roll. A channel is attached to one end of the support substrate for receiving and channeling working fluid away from the rest of the press roll system.
