Abstract
A method is disclosed for introducing material such as cement into sacks of the valve type which are positioned in a magazine adjacent a rotary packing means having a plurality of material filling spouts distributed thereabout and means to supply the material to the spouts. The method relates to positioning the sack magazine adjacent the rotary packing means in a manner such that the foremost sack is positioned adjacent the rotary path defined by the spouts while rotating the rotary packing means in a direction such that the spouts successively and repeatedly approach the bag carrying means in the general direction of rotation. The method further comprises orienting each filling spout relative to the rotary packing means and to the bag carrying means such that the spouts approach the general direction of the opening of the bag closest thereto and successively opening the mouth portion of the foremost bag thereby permitting each approaching spout to enter the opening of the bag and to transport the bag away from its carrying means as the packing means continues to rotate. The cement material is introduced from the filling spout into the bag as it is positioned about the spout. A novel apparatus is disclosed for practicing the inventive method.
