ABSTRACT:
The apparatus has a frame having a top portion with an opening. The frame frictionally supports the middle portion of the string in an initial position behind the opening. A movable funnel is adapted to force a sheet from an initial position above the opening to an intermediate position in which the sheet is located partially through the opening, around the funnel, and in front of the middle portion of the string. A selected quantity of bulk product is poured into the funnel and a knot is tied in the string in front of the sheet. As the knot is tightened, the string forces the funnel upward and the string tightens around the sheet thus forming an enclosed volume with the sheet in a final position around the product.
