Abstract

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.
