Abstract

The disclosure relates to a road finishing machine with a screed for producing a paving layer, wherein the screed includes at least one compacting unit for precompacting paving material supplied to the screed. The compacting unit includes at least one eccentric bushing mounted on an eccentric shaft supporting the same at a desired angle of rotation to thereby continuously variably set a desired tamper stroke of a tamper bar of the compacting unit. For rotating the eccentric bushing on the eccentric shaft, an adjusting mechanism mounted spaced apart from the eccentric shaft and at least partially rotatable along with a rotary motion of the eccentric shaft can be activated. Furthermore, the disclosure relates to a method for a continuously variable tamper stroke adjustment at a compacting unit of a road finishing machine.
