    • The invention relates to an apparatus for maintaining a constant tension on a web of material, in particular on a label web used in a labeling machine (E), said apparatus comprising: a stationary rotary axle device (30) with a geometric rotational axis (M) and a tension compensation device (40) rotatable from a starting position about said rotational axis (M) of said rotary axle device (30), said tension compensation device (40) comprising a force unit (60) which exerts a force on the tension compensation device (40) that counteracts the rotational movement of the tension compensation device (40) from the starting position. It is further provided that the force applied by the force unit (60) is a linear force acting on the tension compensation device (40) at a force application point (65) with a radial spacing to the rotational axis (M) of the rotary axle device (30).
    • 本发明涉及一种用于在材料幅材上保持恒定张力的装置,特别是在贴标机(E)中使用的标签纸上,所述装置包括:具有几何旋转轴线的固定旋转轴装置(30) M)和可从所述旋转轴装置(30)的所述旋转轴线(M)的起始位置旋转的张力补偿装置(40),所述张力补偿装置(40)包括施加力的力单元(60) 所述张力补偿装置(40)抵抗所述张力补偿装置(40)从所述起始位置的旋转运动。 进一步地,由力单元(60)施加的力是在力施加点(65)处作用在张力补偿装置(40)上的线性力,该力施加点(65)具有与旋转体的旋转轴线(M)的径向间隔 轴装置(30)。

    • The invention concerns an apparatus and a method of tensioning a flat web of material to be conveyed, in particular in a printing and dispensing device for labels, which includes: a drive for advancing and retracting the flat web of material, and at least one advance unit and at least one braking unit having a braking roller which are in contact with the web of material and which are drivable by the drive means. It is further provided that the drive has a drive motor that is drivingly connected to the advance unit and the braking unit and that, in a conveyor operation in the advance direction of the web of material, the braking roller of the braking unit is uncoupled from the drive motor.
