A method and mechanism are provided for controlling the movement of a belt. The arrangement may have a moveable member is coupled to an adjustable member. The members are coupled such that when the moveable member is moved in a first direction the adjustable member is move in a first directio n and when the moveable member is moved in a second direction the adjustable member is moved in a second direction. A belt is coupled to the movable member. Moveme nt of the belt in a first direction moves the moveable member in the first direction and movement of said belt in a second direction moves the moveable member in the second direction. A belt tensioner mechanism is connected to the belt so tha t when the belt moves in the first direction a biasing force is created that drives said belt to move a controlled amount in the second direction when movement of the belt i n the first direction is stopped. The arrangement may be employed with a materials feed tray. Side guides for the tray are automatically set correctly for proper feeding from the tray without jamming, skew or off set of the materials.
