A roller, comprising: a substantially cylindrical roller main body having an outer first lateral surface, a first end section and a second end section, which lies opposite the first end section in a longitudinal direction of the roller main body; and a covering layer made of a fibre composite material; wherein the covering layer completely surrounds the first lateral surface of the roller main body in a circumferential direction of the roller main body; wherein a first edge region of the covering layer extends beyond the first end section of the roller main body, is folded over inwards and is fixed in relation to the roller main body, and wherein the roller comprises at least one first clamping element, which fixes the first edge region, wherein the first clamping element is annular or disc-shaped and is arranged coaxially with respect to the roller main body, characterized in that the first end section of the roller main body has, at an end, a curvature which starts from the first lateral surface and around which the first edge region of the covering layer is folded over inwards, and the first clamping element and the first end section of the roller main body have corresponding conical contact surfaces, between which the first edge region is accommodated, or in that the roller further comprises a first end ring, which is arranged coaxially with respect to the roller main body and adjoins the roller main body at the first end section, wherein the first end ring is flush with the first lateral surface and has, on a side facing away from the roller main body, a curvature around which the first edge region of the covering layer is folded over inwards. a substantially cylindrical roller main body having an outer first lateral surface, a first end section and a second end section, which lies opposite the first end section in a longitudinal direction of the roller main body; and a covering layer made of a fibre composite material; wherein the covering layer completely surrounds the first lateral surface of the roller main body in a circumferential direction of the roller main body; wherein a first edge region of the covering layer extends beyond the first end section of the roller main body, is folded over inwards and is fixed in relation to the roller main body, and wherein the roller comprises at least one first clamping element, which fixes the first edge region, wherein the first clamping element is annular or disc-shaped and is arranged coaxially with respect to the roller main body, characterized in that the first end section of the roller main body has, at an end, a curvature which starts from the first lateral surface and around which the first edge region of the covering layer is folded over inwards, and the first clamping element and the first end section of the roller main body have corresponding conical contact surfaces, between which the first edge region is accommodated, or in that the roller further comprises a first end ring, which is arranged coaxially with respect to the roller main body and adjoins the roller main body at the first end section, wherein the first end ring is flush with the first lateral surface and has, on a side facing away from the roller main body, a curvature around which the first edge region of the covering layer is folded over inwards.
