    • A machine for driving and variable length cutting of the paper (10) which forms the armature of the electric motor rotors comprises a feed distance covered by the paper between shaping rollers (11); or these a pressure wheel (15) is located which pushes the paper against a ledge (19) and then slips on the said paper; a paper cutting blade (20) is inserted between the wheel and the ledge; transfer devices are located between the blade and the ledge for the transfer of the cut paper to a bending fixture (22) which gives it the shape of the rotor slot and into which it is being pushed by the inserting devices (31); the rotor (23) is being translated from the conveyor (34) on which it is fed by locking elements (25,26) in the suitable position to receive the paper; such locking elements are directly connected with the position of the ledge to vary the length of the cut paper with respect to the height of the rotor slots where it is being inserted.

    • 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 。

    • A device for cutting a paper web (P) in the transverse direction has a first continuously driven conveyor (1) for moving the paper web through the device and storing the paper web therein (buffer) during cutting in the form of a loop (20), a stationary cutting device (5), a clamping device (4) for temporarily retaining the paper web, and a second conveyor (6) for moving the paper web further after it is stored. The second conveyor (6) comprises a continuously driven transport roller (6a) and several pressure rollers (6b) that can be intermittently pressed by a lifting device (9) onto the transport roller (6a), the paper web (P) being intercalated between the transport roller and the pressure rollers. The clamping device (4) and the lifting device (9) can be driven in step with the cutting device (5), so that the paper web is retained by the clamping device (4) and the pressure rollers (6b) are lifted from the transport roller (6a) while the paper web is cut. The second conveyor (6) is arranged between the clamping device (4) and the cutting device (5). Its transport roller (6a) has a surface layer (8) with the highest possible coefficient of friction with the paper web (P). The lifting device (9) is designed or can be controlled in such a way that the pressure rollers (6b) are lifted from the transport roller (6a) shortly before the paper web is stretched when the loop (20) is undone.
