The apparatus (10) includes a belt loop (28) permeable by air, which is supported by turnover rolls (29, 30). Within the belt loop (28) at least one foil strip (31) is arranged for creating a vacuum effect in the part of the belt loop (28) that transports the web threading tail (16) from the surface preceeding the empty space, and to lead it to the following surface, a vacuum effect is arranged in connection with the first turnover roll (29) of the said turnover rolls (29, 30).</p> |
