    摘要: A method for sorting bags that includes filing past flat one after the other while being separated by a gap; the exterior edges of each bag are checked to determine whether a template and a position of the bag correspond to a calibrated bag or non-calibrated bag. The non-calibrated bags are ejected and the calibrated bags are presented in front of a visual inspection system to determine an acceptable or unacceptable quality of the inspected bag. The acceptable bags are stacked and the unacceptable bags are rejected after they have passed in front of the visual inspection system.

    摘要: A machine for producing bags includes a station for forming a tube, which forms a band of transversely perforated flexible material into a tube, a holding station for retaining the tube, a folding station for forming a bottom at the end of the tube, a folding roller having a folding blade for folding a flap at the end of the tube and a tear-off bar for pinching the tube against the drum, the folding station and the holding station being configured to jointly exert a traction on the tube and detach a portion of the tube. The tear-off bar is disposed behind the folding blade, the machine controlling the rotation of the folding station to synchronize the drum with the front of the tube.
