Abstract
Bag opening device for supermarket check-out counters incorporating bag dispensing machines, comprising a pair of pliers mounted on a pair of guides capable of a reciprocating horizontal motion. The pliers grasp and pull apart the two opposite sides of a bag fed by feeding belts. Each pliers (1, 2) consists of a pair of jaws (9, 9' and 11, 11') meshing with each other by means of a pair of toothed wheels (13, 13' and 14, 14') and pushed towards each other by a compression spring (16, 17) placed between two of their ends. One of the ends of each pliers is provided with a roller (18, 19) which, by interacting with a suitable opening device, counteracts the force of the compression springs (16, 17) thereby opening the jaws (9, 9' and 11, 11') of each pliers (1, 2).
