Abstract
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, which plant comprises at least: forming means (3) for forming individual beaker-shaped filters (105) of filtering material and for releasing each of the beaker-shaped filters (105) inside an impermeable shell (101), means for adjusting the level of each beaker-shaped filter (105) inside the relative impermeable shell (101), and welding means (5) for welding the upper edge of each beaker-shaped filter (105) to the upper edge of the impermeable shell (101) in which the beaker-shaped filter (105) is inserted.
Claims21
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.
