Abstract
A sacking connection for filling sacks that are open at the top with dusty products has two spreading flaps that can be pivoted around horizontal axes. Clamping jaws can be pivoted around horizontal axes and hold the edge of the opening of the sack against the spreading flaps. The front of the spreading flaps are connected by dustproof aprons made of a flexible material and fastened in the vicinity of the side edges of the flaps. When folding-sided sacks are filled, a folding device that can be displaced along with its functions of folding from outside the sacking connection into the space inside the sacking connection is associated with each apron. When flat sacks are filled, a spreading device that can be displaced outward from inside along with its functions of spreading is associated with each apron. The functions of folding or of spreading connect the edge of the sack opening with the aprons to prevent dust from building up on the inside of the edge of the opening of the sack.
