    • Apparatus for depositing liquid droplets in a printing operation employs a member having a receiving surface and being moved at a speed high enough to cause the generation of a gaseous boundary layer along the receiving surface. The stream of droplets is projected at right angles to the rapidly moving receiving surface and a stationary intercepting device is provided to remove, deflect or slow down the boundary layer upstream of the locus where the droplets impinge upon the receiving surface. If the receiving surface is provided on a cylindrical member, the intercepting means may comprise a stationary cylinder surrounding the receiving surface with a clearance of 0.5-2 millimeters. Regardless of the configuration of the receiving surface, the intercepting means may employ one or more stationary deflecting blades or one or more suction nozzles having orifices closely adjacent to the receiving surface immediately upstream of the locus of impingement of droplets.
    • 用于在打印操作中沉积液滴的装置使用具有接收表面的构件,并以足够高的速度移动以使沿着接收表面产生气体边界层。 液滴流与快速移动的接收表面成直角投影,并提供固定的拦截装置以去除,偏转或减慢液滴撞击在接收表面上的轨迹上游的边界层。 如果接收表面设置在圆柱形构件上,则拦截装置可以包括以0.5-2毫米的间隙围绕接收表面的固定的气缸。 拦截装置不管接收表面的构造如何,都可采用一个或多个静止的偏转叶片或一个或多个吸嘴,该吸嘴具有紧邻液滴碰撞位置紧邻接收面的孔口。
