Bag tying machine with a pair of pivoted arms (1,2), a pair of leaf springs (3) between the two arms (1,2) to form a first abutment, and a second abutment (5), preferably formed from a pair of rollers. In use, the open neck of a bag is passed between the arms (1,2) and is gathered together by the leaf springs (3). The gathered together neck of the bag is pushed onto an adhesive tape which is wrapped around the neck of the bag as this passes through the second abutment. The downstream ends of the arms (1,2) are urged together by pneumatic cylinders (6). These are advantageously controlled by a variable pressure controller (9). |
