摘要： A variable torque device for maintaining constant tension in a web of material as the web is unwound from a supply roll. The variable torque device includes a lead screw attached to the shaft of the supply roll via an appropriate gear ratio. A coil spring is located between a hub on the lead screw and a set of rings and friction pads. As the lead screw rotates, the hub translates, thus changing the displacement of the coil spring, which in turn changes the loading of the rings and friction pads. With a full supply roll the coil spring is compressed so as to create an amount of torque to create the desired web tension. As the supply roll unwinds, the rotation of the lead screw translates the hub to expand the coil spring, reducing the torque and maintaining the web tension constant.

摘要翻译： 一种可变扭矩装置，用于当纤维网从供应辊展开时，用于在材料幅材上保持恒定的张力。 可变扭矩装置包括通过适当的传动比附接到供给辊的轴的丝杠。 螺旋弹簧位于导螺杆上的轮毂和一组环和摩擦垫之间。 当导螺杆旋转时，轮毂平移，从而改变螺旋弹簧的位移，这进而改变环和摩擦垫的载荷。 在供应全卷的情况下，螺旋弹簧被压缩以产生一定量的扭矩以产生所需的卷筒纸张力。 随着供应辊的展开，导螺杆的转动使轮毂平移，从而使螺旋弹簧膨胀，减小转矩并保持幅材张力恒定。

摘要： A cylinder with a functional layer (23) and with a supporting body (1), which passes through the cylinder. On the supporting body (1), a sleeve that accommodates the functional layer (23) is supported at ends (2, 5). The supporting body (1) is for its part accommodated on supporting elements (10, 11, 13) provided on the frame side. The cylinder sleeve (3) that accommodates the functional layer (23) can be centered in relation to the axis of rotation (8) by centering faces (6, 7) formed at the ends (2, 5). One end of the cylinder can be exposed at the supporting element (13).

摘要： A belt fuser/finisher including an endless fusing/finishing belt directed around a closed loop path defined by a heated roller and at least one unheated roller. The endless fusing/finishing belt and rollers are mounted on a belt frame that is pivotally attached to a mainframe. The belt frame may be rotated from a latched running position to service position, and the tension in the endless fusing/finishing belt can be relieved, thereby enabling the endless fusing/finishing belt to be easily removed and replaced.
