    • Powder feeding apparatuses (100; 200) and methods. The powder feeding apparatus (100; 200) can include first and second cylindrical rollers (106, 107; 206, 207) adjacent to each other and spaced apart by a gap (108; 208). The first roller(106; 206) can rotate intermittently and independently of the second roller(107; 207). The second roller can rotate intermittently and independently of the first roller. Powder from a hopper (102; 202) is fed through the gap as one or both rollers rotate. The powder feeding method may include a method of feeding powder by intermittently and alternately advancing a first and second roller to dispense powder from the hopper.
    • 粉末供给装置(100; 200)和方法。 粉末供给装置(100; 200)可以包括彼此相邻并由间隙(108; 208)隔开的第一和第二圆柱形辊(106,107; 206,207)。 第一辊(106; 206)可以间歇地旋转并独立于第二辊(107,207)旋转。 第二辊可以间歇地旋转并且独立于第一辊。 当一个或两个辊旋转时,来自料斗(102; 202)的粉末通过间隙进给。 粉末输送方法可以包括通过间歇地并交替地推进第一和第二辊以从料斗分配粉末来供给粉末的方法。
