Abstract
Official abstract text for this publication.
A device ( 20 ) suitable for transforming a continuous and controlled flow ( 320 ) of absorbent material in granules ( 310 ) into an intermittent flow ( 250 ) for providing to receiving means ( 50, 60 ) movable along a direction X, comprising a feed manifold ( 210 ), an outlet nozzle ( 500 ) and a main body ( 200 ), placed between said feed manifold ( 210 ) and said outlet nozzle ( 500 ), configured to cause said absorbent material in granules ( 310 ) to flow along a direction (Y′-Y′) coinciding with the respective axes of symmetry of said feed manifold ( 210 ), said outlet nozzle ( 500 ) and said main body ( 200 ); wherein within said main body ( 200 ) a movable element ( 240 ) is housed, capable of moving alternately between a first and a second working position, in such a way that when said movable element ( 240 ) is located in the first working position, it forms a first accumulation chamber ( 230 ) of the absorbent material in granules ( 310 ) fed in a continuous manner ( 320 ), and a first discharge duct ( 233 ) of said material ( 310 ), and when said movable element is in the second working position, it forms a second accumulation chamber ( 251 ) and a second discharge duct ( 253 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for intermittently applying a flow of granular material on a sheet, comprising: advancing a continuous sheet; providing a continuous and weight-controlled flow of granular material; providing a main body having an inlet mouth, an outlet nozzle, a hollow chamber between the inlet mouth and the outlet nozzle, and a movable element housed in said hollow chamber which oscillates between a first and a second working position, the movable elemen…
