Claim:
A plant for manufacturing single-dose capsules for preparing beverages, comprising: a conveyor ( 2 ) for advancing impermeable shells ( 101 ) in succession along a production line, the production line comprising: a first operative station (A) comprising a forming unit ( 3 ) for forming individual beaker-shaped filters ( 105 ) made of a filtering material and a releasing unit for partially inserting each of the formed beaker-shaped filters ( 105 ) inside an impermeable shell ( 101 ); and a second operative station (B,C) disposed downstream from the first operative station (A) comprising: a regulating unit ( 59 , 60 ) for regulating a level of each partially inserted beaker-shaped filter ( 105 ) inside the relative impermeable shell ( 101 ) and pushing the beaker-shaped filter ( 105 ) to slide into the shell ( 101 ), said regulating unit being independent from the forming unit; and a welding unit welding an upper edge of each beaker-shaped filter ( 105 ) to an upper edge of the impermeable shell ( 101 ) in which the beaker-shaped filter ( 105 ) is inserted.
