Abstract
An apparatus for filling flexible bags with a fluent material that includes a receiving bay, a curvilinear cylinder and a support frame. The receiving bay has an open top for receiving fluent material and funnels down to a discharge opening. The curvilinear cylinder has a top input opening attached to the discharge opening, a bottom output opening, and a curvilinear sidewall therebetween. The curvilinear sidewall has a front wall with an outwardly and downwardly projecting portion that has a predetermined length and extends away from an opposing rear wall of the curvilinear sidewall at a predetermined angle of inclination relative to the vertical direction. The support frame is attached to and supports the receiving bay or the curvilinear cylinder such that the bottom output opening of the curvilinear cylinder is suspended at a predetermined clearance height above the ground. The predetermined angle of inclination, the predetermined length, and the predetermined clearance height are selected such that a bag slipped over the bottom output opening and around the curvilinear cylinder will remain suspended thereby by friction. As fluent material is deposited into the receiving bay and …
