The web comprises a first region (10A), which extends from the folding line to an edge of the web, and a second region (20A) which extends from the folding line to the opposite edge of the web. The apparatus comprises a pressing mechanism (110) which presses the first region of the web to the second side of the web, a supporting mechanism (130) for supporting the web at the folding line, and a guide mechanism (140) which guides the second region of the web towards the first region. The supporting mechanism includes a slide portion which has a friction coefficient of 0.4 or less, to avoid twisting of the web.
