ABSTRACT:
Apparatus for closing and feeding filled bags to conveyor mechanisms of bag tying mechanisms includes a frame and guide rails which support and guide a mounting head for reciprocatory movements in the direction of movement of the conveying mechanism. Lever arms on the mounting head clamp and close the upper portion of the filled bag. First and second pressure operated rams are operatively mounted to impart reciprocatory movements to the mounting head and clamping movements to the lever arms respectively. A reversing valve is connected to a source of fluid under pressure and to the first and second pressure operated rams for controlling the reciprocatory movements imparted to the mounting head by the first pressure operated ram and the movement imparted to the lever arms by the second pressure operated ram in a predetermined sequence.
