<p>The device for the high-speed conveying of post envelopes (2A, 2B) comprises a fixed sole plate (11) extending along the path which the conveyed envelopes follow and along which the envelopes, standing on edge and arranged in series, glide, a motorized endless reference belt (12) stretched along one side of the sole plate, a motorized endless press belt (14) stretched along the other side of the sole plate, and a series of elastically deformable elastomer wheels (16) for elastically pressing against the reference belt in such a way as to grip the envelopes arranged on the sole plate between the reference belt and the press belt. The wheels (16) each have a hub mounted to rotate on a stationary spindle, and an annular tread strip in contact with the press belt, the hub and the annular tread strip of each wheel being connected by elastically deformable circular-arc-shaped fins. The two ends of each fin, which are for connection to the hub and to the annular tread strip of the wheel, lie on a radius of the wheel.</p> |
