Stitching roller for stitching a strip, wherein the stitching roller comprises a roller body that is rotatable about a roller axis, wherein the roller body comprises a circumferential member having a circumference extending about the roller axis, wherein the circumferential member defines a stitching surface that, considered in a radial direction perpendicular to the roller axis, faces away from the roller axis and an internal surface that, considered in the radial direction, faces towards the roller axis, wherein the roller body further comprises a support member extending in a circumferential direction about the roller axis for supporting the circumferential member relative to a rotation shaft, wherein the support member has a connection end that is connected to the circumferential member at the internal surface, a base end for coupling of the stitching roller to the rotation shaft and a radial length in the radial direction between the base end and the connection end, wherein the circumferential member is elastically deformable in a tilt direction about the circumferential direction, wherein the support member is made of a flexible material that allows for the circumferential member to tilt relative to the base end from a neutral orientation into a tilted orientation at at least one position along the circumference, wherein the support member, in the neutral orientation of the circumferential member, has an inner radius at the base end, an outer radius at the connection end and a middle radius at the middle between the inner radius and the outer radius, characterized in that the support member, in an axial direction parallel to the roller axis, comprises a first reinforcement at the middle radius that reinforces the axial stiffness of the support member with respect to the axial stiffness of the support member at the outer radius. wherein the stitching roller comprises a roller body that is rotatable about a roller axis, wherein the roller body comprises a circumferential member having a circumference extending about the roller axis, wherein the circumferential member defines a stitching surface that, considered in a radial direction perpendicular to the roller axis, faces away from the roller axis and an internal surface that, considered in the radial direction, faces towards the roller axis, wherein the roller body further comprises a support member extending in a circumferential direction about the roller axis for supporting the circumferential member relative to a rotation shaft, wherein the support member has a connection end that is connected to the circumferential member at the internal surface, a base end for coupling of the stitching roller to the rotation shaft and a radial length in the radial direction between the base end and the connection end, wherein the circumferential member is elastically deformable in a tilt direction about the circumferential direction, wherein the support member is made of a flexible material that allows for the circumferential member to tilt relative to the base end from a neutral orientation into a tilted orientation at at least one position along the circumference, wherein the support member, in the neutral orientation of the circumferential member, has an inner radius at the base end, an outer radius at the connection end and a middle radius at the middle between the inner radius and the outer radius, characterized in that the support member, in an axial direction parallel to the roller axis, comprises a first reinforcement at the middle radius that reinforces the axial stiffness of the support member with respect to the axial stiffness of the support member at the outer radius.
