PURPOSE: To automatically tie the mouth of a bag packed with a fixed quantity of screening residue collected form channels in a sewage disposal plant, pump house, or the like and rinsed and dehydrated.
CONSTITUTION: Bag-holding frames 9, in each of which an empty bag 7 to be filled with dehydrated screenings residue is set, are arranged at regular intervals on a turntable 8. This turntable 8 is turned pitch by pitch intermittently with the interval between two adjacent bag-holding frames 9 as one pitch. At a mouth-tying position above the turntable 8 a bag-holding means is provided; each bag-holding means consists of bag grippers 10 provided externally and a cord holder which supports two tying cords forming loops passed through the mouth of the bag and hitched to the cord holder itself. Hooks 13 are passed through the loops of the tying cords, which are hitched to the cord holder, and to make up a mouth-tying movable device 14, two trucks 18 for the hooks are provided as means of tying the mouth of the bag by moving the hooks 13 away from each other.
