    • A method and apparatus is disclosed for forming a zero-speed, butt splice to join together a web from a new roll of material to a web which is from an expiring roll of material and which should be run, at a relatively high speed, through a web processing operation, such as a disposable diaper manufacturing line, under relatively constant, relatively low tension along a predetermined path of travel that includes a running web festoon means having floating dancer rollers and the running web processing operation. To form the butt splice, the leading end of the new web is trimmed by moving one knife wheel assembly along the cutting edge of an anvil. A piece of tape is applied to the leading end so that a portion of the tape projects downstream from that end. The expiring web is held against the anvil and trimmed along the same cutting edge of the anvil. The trailing end of the expiring roll is also simultaneously adhered to the downstream portion of the tape. Only the portion of the expiring roll adjacent to the anvil is momentarily stopped while the expiring web is trimmed and adhered to the leading end of the new roll. The stoppage is sufficiently short so that downstream portions of the expiring web can, in the interim, be withdrawn from the festoon means so that web continues to run, at its relatively high speed and under it relatively constant, relatively low tension, through the web processing operation.
    • 公开了一种用于形成零速对接接头的方法和装置,其将纤维网从新的材料卷连接到幅材上,所述幅材是从过期的材料卷并且应该以较高的速度通过 诸如一次性尿布生产线的卷筒纸加工操作沿着预定的行进路线处于相对恒定的相对低的张力下,包括具有浮动浮动轮的行进卷筒纸装置和运行的卷筒纸处理操作。 为了形成对接接头,通过沿着砧座的切割边缘移动一个刀轮组件来修剪新网的前端。 将一条胶带应用于前端,使得一部分带从该端延伸到下游。 过期的腹板固定在砧座上,并沿着砧座的同一边缘修剪。 过期辊的后端也同时粘附到带的下游部分。 只有与砧座相邻的到期辊的部分暂时停止,而过期的纸幅被修剪并粘附到新卷的前端。 停止时间足够短,使得过期幅材的下游部分可以在过渡期间从吊架装置中取出,使得纸幅以相对较高的速度继续运行并且在其相对恒定的较低张力下通过纸幅 处理操作。

    • Disclosed herein is a method for splicing the leading end of a standby web to a running expiring web, rotatably supported on an unwind means, comprising the steps of: providing a running web storage means for maintaining, at a substantially constant value, the speed at which the running web leaves the web storage means when the speed of the running web entering the web storage means changes; restraining the running web with a web guide means; applying a braking force to the web guide means so that the tension in the running web between the web guide means and the unwind means is almost zero; sensing the end of the running web with a web tail sensing means, after it has become disengaged from the unwind means; stopping the running web by grasping the running web with a clamp means, after the tail end of the running web has passed through the web tail sensing means; effecting a splice between the leading edge of the standby web and the running web, while both webs are stationary; and severing the running web. An apparatus for accomplishing the above method is also disclosed.
