Abstract
A tamper of a screed includes a tamper bar secured to a connecting rod in which an eccentric bushing is rotatable. The eccentric bushing is adapted to be rotationally displaced on an eccentric section of a drive shaft relative to the eccentric section and to be rotationally coupled with the eccentric section at relative rotational positions defining different stroke lengths of the tamper bar. A changeover between the rotational positions is accomplishable by a reversal of the direction of rotation of the drive shaft. The eccentric bushing is adapted to be locked at each respective rotational position by means of a locking and/or coupling device against inadvertent displacement from the respective rotational position. The locking and/or coupling device is adapted to be released and/or engaged automatically or by remote control for effecting a changeover from one rotational position to the next.
