<p>Strip with a wedge-shaped cross section (21), extends across the surface (17) of charging table (10). Its front surface (22) falls away. When the charging table is fully-advanced, the scraper (15) rests on the strip (21), especially on its front surface (22), which falls away. The scraper moves relative to the table, when the latter is retracted (20), maintaining constant contact with the surface.</p> |
