One of SCA’s plants is situated at Lilla Edet in the West of Sweden. Here, paper has been produced since the end of the 19th century and tissues since the '40s. FlexLink has been a supplier of conveyors to SCA since the beginning of the 80s. Gert Carlson, Production Process Technician, remembers the first installation: “It was already in 1983, we were rebuilding the plant and FlexLink conveyors were installed for handling toilet paper tissue.” After that, FlexLink has made many installations through the years. 

Complete handling system
In 1996, SCA upgraded Line 12 and asked FlexLink to suggest a conveyor system for handling the rolls to the Optima baggers and handling the packs from the Optimas to the display palletizers. Since space was limited, a solution also had to be made for handling the cores from the corewinder to the rewinder. The rewinder was equipped with two 4-lane logsaws each feeding one bagger. This solution enabled a very flexible production, without limiting the output from the rewinder. 

When running 4-packs only two lanes per saw are used, for 6-packs three and for 8-pack all four lanes are in operation. The rolls are run on four-lane XL (65 mm) conveyors. After the baggers the packs are conveyed either to two Hayssen Titepak or to the display palletizers. The destination is selected by setting a vertical pivot conveyor to the desired out feed conveyor. When running to the display palletizers, the packs are handled on a two-lane XL conveyor, laying down with the cores across the conveyors. 

Automatic closing device
The production from the two baggers are merged using a mechanical device, "traffic police", that without any controls or pneumatics, automatically closes one lane when products are coming from the other. There are two palletizers normally dedicated to one converting line each, but when only one converting line is running display pallets it can use both palletizers.
