Connecting at least two starting plates made of plastic foam to a plate (2, 3), preferably halogen-free operated polystyrene foam plates (25) as starting plates to plates, comprises (a) using starting plates, which are extrusion uncovered at the contact surface, (b) welding the compound of the starting plates, (c) loading the contact surfaces with a temperature, (d) heating the contact surfaces with a strip-shaped heat source, and (e) pressing the heated starting plates against each other. Connecting at least two starting plates made of plastic foam to a plate, preferably halogen-free operated polystyrene foam plates as starting plates to plates with a minimum thickness of 70 mm, preferably with a minimum thickness of 100 m, comprises (a) using starting plates, which are extrusion uncovered at the contact surface, (b) welding the compound of the starting plates by thermally welding the starting plates at the contact surfaces, (c) loading the contact surfaces with a temperature, which is at least 100[deg] C, preferably at least 400[deg] C above the melting/softening temperature of the polymer, (d) heating the contact surfaces with a strip-shaped heat source, and moving the starting plates over the heat source, and (e) pressing the heated starting plates against each other. |
