Abstract
The invention relates to a laying plank for a road finishing machine, comprising a basic plank (1) which exhibits two central upright cheeks (2) to which a telescopic cylinder (3) is attached on each side which guides an inner movable cheek (8) of an extensible plank (4) for the lateral prolongation of the basic plank (1) and engages its outer movable cheek (5) for extension, guide rods (7) parallel to the cylinder axis being provided respectively between inner and outer cheeks (5,8) which are guided by an outer cheek (11) connected firmly to the basic plank (1). In order that the basic plank (1) can be enlarged practically to double width by the extensible planks, it is provided that the guide rods (7) are constructed as telescopic rods and the extensible planks (4) are respectively connected to an auxiliary cheek (6) adjacent to the inner movable cheek (8), the auxiliary cheeks (6) being respectively guided and retained by an auxiliary guide means (13, 14 ) fastened to the respective inner movable cheek (8), parallel to the cylinder axis and extending outwards.
