Method and machine for producing bags containing fiber material

A machine for producing bags containing fiber material, characterized in that it comprises two devices for feeding fiber material for forming relative continuous layers of fiber material;

• two dispensing sections for separating in succession portions of fiber material from each of the continuous layers and moving them along respective predetermined paths;
• a first transfer conveyor equipped with compacting means designed for receiving pairs of portions of fiber material wherein each portion comes from one of the two predetermined paths;
• a second transfer conveyor equipped with pairs of supporting elements each designed for receiving and holding a bag for containing a portion of fiber material;
• transfer means for simultaneously transferring the portions of fiber material forming part of each pair from the containment and compaction elements of the first transfer conveyor into respective housings of a third transfer conveyor, for transferring them from the housings of the third transfer conveyor into respective containment bags carried by the pairs of supporting elements of the second transfer conveyor, and for transferring the pairs of containment bags housing respective portions of fiber material from the respective supporting elements of the second transfer conveyor to a fourth transfer conveyor;
• and conveyor means for moving in succession the bags housing respective portions of fiber material to a folding unit at which the bags are closed.
