The invention relates to the manufacture of plastic boats in a sandwich construction using so-called square-cut cellular-plastic material as spacing material. For the purpose of ensuring that the gaps of the cellular-plastic material (6) are completely filled, a curable filler substance (4) is applied to the inner surface of the outer laminate (3) and a spacer member (mesh 8) and a sealing layer (plastics 9) are placed over the cellular-plastic material (6). A suction element (10, 11) connected to a vacuum source of about 0.9 atmospheres is then activated, such that the filler substance is positively drawn up into the gaps (5) in the cellular-plastic material (6). This takes place so quickly that it is possible to apply filler immediately and to apply the inner laminate (7) wet-in-wet. |
