    • An improved powder delivery system for use in dispensing powder to a printing press. The improvements include an agitator system for the powder reservoir, a wiper block for use with a curved feed roller, a split air flow amplifier which is openable for cleaning, a flow-through rotary manifold for distributing powder to press and an improved powder spray block. The foregoing elements minimize the flow restrictions and enhance air and powder flow through the system. A control panel is provided at the operator's console which is remote from the mounting position for the powder delivery apparatus. The control panel provides for, among other things, the delivery of powder at a fixed rate regardless of press speed or in accordance with variations in press speed. For example, in accordance with a factory determined linear relationship or an operator entered relationship. Such data can be stored for future reference and use.
    • 一种用于将粉末分配到印刷机的改进的粉末输送系统。 这些改进包括用于粉末储存器的搅拌器系统,用于弯曲进料辊的擦拭器块,可打开清洗的分流式气体放大器,用于将粉末分配到压力机上的流通旋转歧管和改进的粉末喷射块 。 前述元件使流量限制最小化并增强通过系统的空气和粉末流。 控制面板设置在操作台的远离粉末输送装置的安装位置的控制台上。 除了别的以外,控制面板还提供了无论压机速度或按照压力变化的变化,以固定的速率输送粉末。 例如,根据工厂确定的线性关系或操作员输入的关系。 这些数据可以存储以供将来参考和使用。
