The invention relates to a method for continuously manufacturing elastic pants (28), wherein a flat web material (1, 16, 19) is continuously conveyed in a longitudinal direction (8) of the web material (1, 16, 19), is shaped into a closed tube (4), and is closed in the longitudinal direction (8). The closed tube (4) forms a first outer layer (9). Elastic threads (10) in the form of a tubular reinforcement are then wound around the first outer layer (9) in the conveying direction (8) in such a way that the elastic threads (10) are taut when the outer layer (9) has a convex shape. A second outer layer (15) is then continuously applied to the elastic threads (10) in the conveying direction (8) and is joined to the elastic threads (10) and/or the first outer layer (9). The first outer layer (9), the elastic threads (10) and the second outer layer (15) form an elastic pants web material (21). Further down in the conveying direction (8), the pants web material (21) is closed along a joining section (29) in regular intervals such that the joining section (29) forms two approximately equally large opening sections that lie opposite each other in the transverse direction. Further down in the conveying direction (8), the pants web material (21) is cut at a distance from the joining section (29) such that a pair of elastic pants (28) is formed.
