ABSTRACT:
A process is disclosed for manufacturing and protecting containers used in nurseries and horticulture, presenting an upper opening obturated by a cover for protecting the substrate previously filled in said container. Each container is subjected at least to an operation for fixing a sheet on its opening, thus closing it, at least an operation of perforating the sheet at its center, at least an operation of cutting the sheet to disconnect it from the web of sheet, and an operation for trimming the excess sheet by cutting it around the pot. These operations are carried out as the pots advance on a machine. The invention also relates to such a machine and to the containers produced.
