An apparatus for leading a web threading tail over an empty space formed between two surfaces, between which the apparatus (10) is arranged. 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 preceding 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 turnover rolls (29, 30).
