Preferably, however, it is used for collecting bags, which consist exclusively of a flexible material, for example polyethylene (PE). However, it is equally suitable for collection bag with a part, in particular a lid, made of a hard material. It is particularly suitable for drainage collection bags with a rigid head part, as they have been marketed for example by the Applicant for years.
  • PE polyethylene
  • the parts of the bag are transported by the first conveyor 4, wherein they are preferably still or again charged with one or the cleaning liquid. In this case, the cleaning liquid now flows out of the lower nozzles 30 '.
