Method for producing a piping (21) with the following steps: - providing a flat material (6) comprising at least one decorative layer, - guiding the flat material (6) through a guide means (2), wherein the flat material (6) is at least partially folded is, in such a way that the flat material is curved in a plane orthogonal to the guide direction with an apex (12) of the curvature and two legs (13, 14), - introduction of a first area (11) of a retaining profile (7) between the two legs (13, 14) of the at least partially folded sheet material (6), - pressing the legs (13, 14) of the sheet material (6) in such a way that the legs (13, 14) are moved towards one another, characterized in that a retaining profile (7) is used which has a degree of hardness less than 60 Shore-A and which has a second area (29) with at least one anchor, the anchor being compressible in a lateral direction is designed to exert a force directed in the lateral direction in the compressed state.
