    • The present invention relates to an oscillating assembly for pivoting a blanking die that is constructed and arranged to cut blanks from sheet material. The oscillating assembly comprises a die supporting structure that pivots about a pivot axis. The die supporting structure receives and supports the die such that the sheet material can be fed into the die in a feeding direction and such that the pivoting of the die supporting structure pivots the die relative to the sheet material. A reversible rotary driving assembly rotates a rotatable output shaft in opposing first an second rotational directions. A linearly movable die driver is operatively connected to the output shaft such that (a) rotating the shaft in the first rotational direction thereof moves the die driver generally linearly in a first die driving direction and (b) rotating the shaft in the second rotational direction thereof moves the die driver generally linearly in a second die driving direction opposite the first die driving direction. The die driver is operatively connected to the die supporting structure such that (a) moving the die driver in the first die driving direction thereof as aforesaid pivots the die supporting structure to a first cutting position wherein the blanking die can cut a first blank from the sheet material fed therein and (b) after cutting the first blank and advancing the sheet material relative to the die in the feeding direction, moving the die driver in the second die driving direction thereof as aforesaid pivots the die supporting structure to a second cutting position wherein the blanking die can cut a second blank from the sheet material.

    • In a web cutter where a blade is used to cut a continuous paper web into sheets, a tractor is used to move the web past the blade for cutting. The tractor operates in a start-and-stop cycle so that the web is temporarily stopped to allow the blade to lower and shear the web. The tractor accelerates in the next cycle to move another length of paper downstream from the blade. A high-speed cutter requires high acceleration of the tractor. This acceleration force causes the web to whip up uncontrollably, causing the web to break or wrinkle. To reduce the web breakage, a moving mechanism positioned upstream from the tractor and operate a second motion cycle is used to move the web toward the tractor such that a loop of paper is formed upstream of the tractor, thereby reducing the whipping action of the web.
    • 在使用刀片将连续纸幅切割成片材的卷筒纸切割器中,使用拖拉机将纸幅移动通过刀片进行切割。 拖拉机在起动和停止循环中操作,使得纸幅暂时停止,以允许叶片降低和剪切幅材。 拖拉机在下一个循环中加速,从刀片下游移动另一长度的纸张。 高速切割机需要拖拉机的高加速度。 这种加速力使得网片不受控制地打起来,导致网片断裂或起皱。 为了减少纸幅断裂,使用位于拖拉机上游并且操作第二运动周期的移动机构将纸幅朝向拖拉机移动,使得在拖拉机的上游形成一圈纸,从而减少幅材的搅打动作 。
