    • A rotary bag machine and method for making bags from a film are disclosed. They include a rotary drum, an accumulation nip, a blanket that positions the film against the drum, and a blanket tensioner located away from the accumulation nip. The drum includes at least one seal bar mounted thereon, and the accumulation nip provides the film to the drum. Various aspects include the accumulation nip being in a fixed position independent of changes of the drum diameter, and/or the path from the accumulation nip to the drum being fixed in length, independent of changes of the drum diameter. An accumulation sensor and a controller that controls the accumulation nip speed and the drum speed in response to the sensor are provided in one embodiment. The speed control is in response to the speed of the film, the rate of change of a function of the input, response history, and/or a setpoint, in various alternatives. A drawtape module and a powered unwind are disposed in a single module with the rotary drum, in another embodiment. A registration mark sensor is located upstream of the accumulation nip, along a path having a fixed length to the drum, in another embodiment. The sensor may be a print sensor.
    • 公开了一种用于从薄膜制造袋子的旋转袋机和方法。 它们包括旋转鼓,聚集辊隙,将膜定位在滚筒上的橡皮布以及位于远离聚集辊隙的橡皮布张紧器。 滚筒包括安装在其上的至少一个密封条,并且聚集辊隙将胶片提供给滚筒。 各种方面包括不依赖于鼓直径的变化的积聚辊隙处于固定位置,和/或从堆积辊隙到鼓的路径被固定在长度上,而与鼓直径的变化无关。 在一个实施例中提供了累积传感器和控制器,其响应于传感器来控制累积咬合速度和鼓速度。 速度控制是响应于电影的速度,输入功能的变化率,响应历史和/或设定点,在各种替代方案中。 在另一个实施例中,抽屉模块和动力退绕装置设置在具有旋转滚筒的单个模块中。 在另一个实施例中,对准标记传感器沿着具有固定长度的路径位于累积辊隙的上游。 传感器可以是打印传感器。
