FIELD: agriculture.SUBSTANCE: invention relates to agriculture and can be used in balers. The drive roller for actuation of at least one flat tape comprises a housing with a coating applied on it at discrete parts. Between the discrete parts of coating a continuous peripheral channel is formed, having a first diameter relative to the rotation axis of the drive roller. The coating has a plurality of first grooves on its surface and at least one peripheral groove intersecting the first grooves within the width of each discrete part of the coating. The first grooves are substantially nonparallel to the direction of displacement and comprise two inner walls connected by a bottom part having a second diameter relative to the axis of rotation of the drive roller. The second diameter of the bottom part is greater than the first diameter of the peripheral channel.EFFECT: use of proposed drive roller for actuating the flat tapes prevents the accumulation of foreign mass between the drive roller and the tape.9 cl, 12 dwg |
