Method and machine for producing bags containing fibre material

摘要

A method for producing bags (64) containing fibre material, comprises the steps of forming at least one continuous layer (16) of fibre material; separating in succession portions (23) of fibre material from the continuous layer (16) and moving them along a predetermined path; feeding each portion (23) of fibre material to respective containment and compaction elements (50) of a first transfer conveyor (48); feeding an ordered succession of bags (64) containing respective portions (23) of fibre material to respective supporting elements (70) of a second transfer conveyor (58); transferring the portions (23) of fibre material from the containment and compaction elements (50) of the first transfer conveyor (48) into respective housings (56) of a third transfer conveyor (54); transferring the portions (23) of fibre material from the housings (56) of the third transfer conveyor (54) inside respective containment bags (64) carried by supporting elements (70) of the second transfer conveyor (58); transferring the containment bags (64) housing respective portions (23) of fibre material from the respective supporting elements (70) of the second transfer conveyor (58) to a fourth transfer conveyor (74); and moving in succession the bags (64) housing respective portions (23) of fibre material to a folding unit (G) at which the bags (64) are closed.
