Feeding device for processing a continuous moving web in a station in which the web is acted on while in a standstill position
摘要：
A feed device for advancing a web into a processing station which acts on the web while the web is in a standstill position. The feeding device includes a first drive roller around which a second swivel roller oscillates between an upstream and downstream position to create a loop to take up the web during a dwell in the movement of the web through the processing station. The swivel roller is driven at the same speed as the drive roller by an arrangement of drive pinion and a counterweight is also rotated at the same rate by a gear arrangement. The counterweight is mounted on a lever which will oscillate in an opposite direction to the movement of the swivel roller so that the moment of inertias are balanced during operation of the device and the torque on the drive for the rollers is balanced.
摘要（中）：

一种用于将幅材推进到幅材处于停止位置时作用在幅材上的处理站的进给装置。 馈送装置包括第一驱动辊，第二旋转辊在其周围在上游位置和下游位置之间振动，以在卷筒纸移动通过处理站期间停留期间产生回卷以吸收卷材。 旋转辊通过驱动小齿轮的布置以与驱动辊相同的速度被驱动，配重也通过齿轮装置以相同的速率旋转。 配重安装在杠杆上，该杠杆将以与旋转辊的运动相反的方向振荡，使得在装置的操作期间惯性矩平衡，并且用于辊的驱动器上的扭矩是平衡的。
