ABSTRACT:
This invention relates to a feeder including a roller seat, a threaded control shaft which has one end protruding out from the roller seat, and an adjusting knob connected with the end of the threaded control shaft for changing the rotating speed of the conveying rollers of the feeder by means of manually rotating the adjusting knob. The protruding end of the threaded control shaft is surrounded by a sleeve member so as to protect the protruding end of the threaded control shaft from the accumulation of foreign matter. The sleeve member has predetermined graduation marks scaled on an outer surface of the sleeve member to show the rotating speed of the conveying rollers when the adjusting knob is rotated downwards and upwards.
