发明名称 METHOD AND DEVICE FOR FORMING ABSORBING CORES MANUFACTURED FROM FIBROUS MATERIAL STACKED WITH AIRFLOW
摘要 FIELD: medicine; medical engineering. SUBSTANCE: device has the first source for supplying fibrous material, carried off with airflow and the first air-added stacking means connected to the first source for supplying fibrous material, carried off with air flow. The means has the first movable perforated forming unit for producing the first part of air-stacked part of absorbing core. The device also has source unit for supplying fibrous material and appropriate separate absorbing material particles, carried off with airflow. The second air-added stacking means is connected to the means for supplying fibrous material and appropriate separate absorbing material particles, carried off with airflow. It has the second movable perforated forming unit for producing the second part of air-stacked part of absorbing core being a mixture of uniformly distributed fibrous material and appropriate separate articles. The second air-added stacking means is arranged with respect to the first one in a way that the produced second part from the second forming unit and laying it over the first formed part arranged on the first forming unit. EFFECT: easily combinable matching layers. 37 cl, 3 dwg
