    • Systems and methods of registration system control are provided that compensate for differences in physical properties of various substrates being transported through the system that impact the displacement of the substrate through a given path. Exemplary systems of the invention include at least one roll pair formed by a first, driven roll and a second roll defining a nip therebetween that is part of the transport path through which a substrate is passed. A prestored lookup table includes empirically- or theoretically-derived compensation factors for plural different kinds of substrates, with each compensation factor being based on physical characteristics of the substrate that impact actual travel length of the substrate along the transport path, such as the substrate's mass per unit area, which has been found to have a strong correlation with a substrate's bending stiffness, which has been found to have a strong correlation with detected deviations in linear travel path. Upon input or determination of the substrate being registered, the system adjusts the drive profile of the drive roll by the compensation factor. This is preferably by adding the derived paper path length adjusting value to the actual nominal length between the drive roll pair and a desired registration position to take into account an arcuate or non-linear travel path due to flexure of the substrate. A suitable compensation factor compensates for the amount of angular rotation of the drive roll so that the travel path length of the substrate is appropriated compensated.
    • 提供了配准系统控制的系统和方法,其补偿通过系统传送的各种衬底的物理性质的差异,该衬底影响衬底通过给定路径的位移。 本发明的示例性系统包括由第一从动辊和第二辊形成的至少一个辊对,其限定了在其间的辊隙,其是衬底通过的传送路径的一部分。 预先存储的查找表包括用于多种不同种类的衬底的经验或理论上的补偿因子,其中每个补偿因子都是基于衬底的物理特性,其影响衬底沿传输路径的实际行进长度,例如衬底质量 已被发现与基板的弯曲刚度具有很强的相关性,已被发现与线性行进路径中检测到的偏差具有很强的相关性。 在输入或确定正在登记的基板时,系统通过补偿因素调整驱动辊的驱动轮廓。 优选地,通过将​​导出的纸张路径长度调节值添加到驱动辊对和期望的配准位置之间的实际标称长度,以考虑由于基板的挠曲而导致的弓形或非线性行进路径。 适当的补偿因数补偿驱动辊的角度旋转量,从而适当地补偿衬底的行进路径长度。

    • A process and apparatus related to a workstation adjacent to a traveling web including a device for intermittently performing an operation affecting the web. An important application involves ultrasonically welding multiple layers of a traveling web. First and second rollers on opposite sides of the workstation are simultaneously shifted in a direction counter to the machine direction each time a bonding force is applied. The overall running speed in the machine remains at a constant velocity due to the resultant festooning effect and thus the dwell time for bonding is increased. Thus the effective operating speed of processed having finite limits may be increased at least 33%. The first and second rollers are eccentrically rotationally mounted, respectively, on third and fourth hollow rollers which are provided with eccentrically positioned hollow cylindrical openings which, in turn, are mounted, respectively, on shafts positioned perpendicularly to the machine direction. Shifting of the rollers is effected by simultaneous rotation of the rollers. Preferably, the first and second rollers are driven synchronously in a first rotational direction and the third and fourth rollers are driven synchronously in the opposite rotational direction.
    • 与邻近行进网的工作站相关的处理和装置,包括用于间歇地执行影响网的操作的装置。 一个重要的应用是超声波焊接多层行进网。 每次施加接合力时,在工作台的相对侧上的第一和第二辊同时沿与机器方向相反的方向移动。 由于所产生的浮雕效应,机器中的总运行速度保持恒定的速度,因此粘结的停留时间增加。 因此,具有有限限制的加工的有效运行速度可以增加至少33%。 第一和第二辊分别旋转地安装在第三和第四中空辊上,第三和第四中空辊设置有偏心定位的中空圆柱形开口,该中空圆柱形开口又分别安装在垂直于机器方向定位的轴上。 辊的移动通过辊的同时旋转来实现。 优选地,第一和第二辊在第一旋转方向上同步地驱动,并且第三和第四辊在相反的旋转方向上同步地被驱动。
