ABSTRACT:
A roller mounting includes an elongated shaft having an end rotatably and slidably disposed within a bore formed in a mounting bracket, and a roller rotatably mounted on an eccentric portion provided on the other end of the shaft. The shaft is retained in the bore by a device which may be rotated in unison with the shaft to cause lateral movement of the roller relative to the bracket without imparting axial movement to the roller and which may be rotated relative to the shaft to cause axial movement of the shaft for moving the roller in an axial direction independently of the lateral adjustment.
