摘要

Improvements in the mechanisms of fastening and filling bags in packaging-dosing machines, characterized in that the packaging chain is provided with a plurality of bag support devices, protruding above as forks, each of which has the less one of its arms articulated and elastically requested with tendency to keep it separate from the other, each arm presenting a lower stump, introducing these stumps in the mouth of the bag, which thus ensures tight and open, leaving the bag suspended, being possible the penetration of the trunnions into the bag as one arm approaches the other, overcoming the elastic resistance, to then retain the bag when the elastic tendency itself acts, and comprising at least one metering hopper in the same packaging chain, at the exit of which is disposed a landfill with descending-ascending movement that allows it to enter-exit in the mouth of the bag to be filled, leaving such a dump formed by two parts between which an elongated lower opening is determined, with lips that are introduced into the bag when making the descent, and at least one of these two parts being tiltable for determine the separation between those lips when the descent is made, in a repeated movement that determines the expulsion of the dose of product deposited in the landfill.
