Valetsky B. Increasi of efficiency of work of machines for packing of huge cargo with the film welding mechanisms

Dissertation is directed on the improvement of existing and creation of new equipment for the huge cargo packing with welding mechanisms and increase of efficiency of his work. The complex of criteria is developed for the estimation of efficiency of work of packing machine with the mechanisms of welding and the resulted criterion of efficiency, taking into account the productivity, reliability and cost, both making and exploitations, is formulated. The new method of packing of huge cargo is developed, the estimation of quality of the weld-fabricated connections of pellicle materials is Offered to conduct by a complex index, taking into account durability of guy-sutures, waviness and impermeability.
