    • A teaseling and/or fluffing machine for fabric and knitwork, with tension control, including a load-bearing structure with two sidepieces supporting at least one drum which rotates about a central shaft and supports on its two lateral endpieces two series of teaseling and/or fluffing rollers, of with-pile type and against-pile-type. These rollers are arranged along generatrices of the drum with those of one series rotating relative to those of the other under independent drive. A fabric to be treated passes about the teaseling and/or fluffing rollers and is fed to the machine by a driven feed roller and extracted therefrom by a driven exit roller. Brushes are provided which interact alternately with the teaseling and/or fluffing rollers. Between the feed roller and the drum and, respectively, between the exit roller and the drum, there are interposed two further rollers, the shafts of which are rotatably supported on automatic tension control devices fixed to the load-bearing structure and controlling respective motors of the feed roller and exit roller, in order to automatically control and regulate the fabric tension, both at its entry and at its exit.
    • 一种用于织物和针织物的起绒和/或起毛机,具有张力控制,包括承载结构,其具有支撑至少一个滚筒的承载结构,所述至少一个滚筒围绕中心轴旋转并且在其两个侧向端部上支撑两个系列的柚木和/或 起绒辊,桩型和反绒头型。 这些辊子沿着鼓的母线排列,其中一个系列的转子相对于另一个在独立的驱动下旋转。 待处理的织物绕着茶叶和/或起毛辊穿过,并通过驱动进给辊送入机器,并通过驱动的出口辊从其中提取。 提供与冲洗和/或起毛辊交替交替的刷子。 在进给辊和滚筒之间,并且在出口辊和滚筒之间分别插有两个另外的辊,其轴被可旋转地支撑在固定到承载结构上的自动张力控制装置上,并且控制相应的马达 进料辊和出口辊,以便在进入和退出时自动控制和调节织物张力。

    • A brake (26) employed to control web tension on a roll stand (10) is provided as a generator whose rotor shaft (38) is mounted on the roll stand's core-coupler spindle (16). The rotor (36) may be journaled in the generator's stator assembly (52) so that the spindle (16) supports the entire generator, and alignment problems that might otherwise require complicated flexible couplings, and excessive axial protrusion of the generator into service aisles are avoided. In another version, the generator stator (52) is mounted directly on the roll stand's arm (12) so that generator rotor-stator alignment is set by the journaling of the spindle (16) in the arm (12). Accurate web tension results from current feedback for control of the generator load.
    • 设置用于控制卷筒架(10)上的卷筒纸张力的制动器(26)作为其转子轴(38)安装在辊架的芯联轴器(16)上的发电机。 转子(36)可以安装在发电机的定子组件(52)中,使得主轴(16)支撑整个发电机,否则可能需要复杂的挠性联轴器的定位问题以及发电机进入维修通道的过度的轴向突出是 避免。 在另一种形式中,发电机定子(52)直接安装在轧辊机座的臂(12)上,从而通过主轴(16)在臂(12)中的延伸来设定发电机转子 - 定子对准。 用于控制发电机负载的电流反馈导致精确的幅材张力。
