A machine for producing bags from two parallel strips of material and for filling a solid or liquid product into the bags. The strips are welded together to form individual bags which are carried through subsequent stations, including filling and closing stations, suspended on two flexible blades engaging below folded edge zones of the strips. The blades are pulled apart to open the bag mouth in the filling station in which a two-part funnel is introduced into the bag mouth and opened to clamp the mouth against the flexible blades while the bag is being filled through the funnel. The bags are fed to the closing station with their mouths slightly open so that a rotatable tube may be inserted therein and rotated to twist the bag mouth together while it is held to the tube by suction and the body of the bag is held against rotation.
