Washing machine for longitudinal profiled sections with a film cover, and method for washing longitudinal profiled sections

A washing machine for longitudinal profiled sections, comprising a drum which can be rotated about a horizontal rotational axis and comprises a plurality of receiving areas which are arranged along the circumference of the drum, which are laterally delimited by lamellas, which are open in the radial direction, and into which the longitudinal profiled sections can be inserted along the longitudinal direction (L), also comprising a receiving opening for the longitudinal profiled sections, an outlet opening at a distance from the receiving opening in the rotational direction (R) of the drum for the longitudinal profiled sections, and a transport path which runs between the receiving opening and the outlet opening for the longitudinal profiled sections, also comprising at least one washing fluid outlet by which the receiving areas pass when the drum is rotating and out of which the washing fluid flows into a currently passing receiving area, whereby the inserted longitudinal profiled section is washed, characterised by at least two drums arranged adjacent to one another and enable an automatic transfer of the longitudinal profiled sections from the drum to the further drum, and the drum is provided with a washing fluid and the further drum is provided with a further washing fluid and characterized by a flexible film for each drum having two tensioning devices containing a tensioning support and a tensioner each on both long edges, which are acting together, whereby the film covers the receiving areas passing by the at least one washing fluid outlet, thereby directly contacting the lamellas of the passing receiving area, and a long edge of the flexible film which extends along the outlet opening is configured to be adjustable in the circumferential direction of the drum by actuating the tensioners such that the angular position of the film is set and remains fixed once it has been set in position relative to the frame by combined adjustment of the two tensioners and the height of the outlet opening is adjustable in the circumferential direction and adapted to the diameter of the longitudinal profiled section such that the longitudinal profiled section does not fall but only rolls out of the receiving areas of the drum.
