Abstract
A button feeding device includes a button alignment shaft having a longitudinal axis which is displaceable with respect to the longitudinal axis of the main drive shaft. The button alignment shaft and the main drive shaft are advantageously linked for rotation by a coil spring. The device has a pin holder which aligns the button and transfers it into a button clamp, a carriage being provided to move the pin holder over a substantially linear quadrangular path.
