The disclosure relates to a positioning apparatus for workpieces whose length is to be adjusted. The apparatus includes a conveyor which advances the workpieces. Beside this feed conveyor, there is an additional conveyor on which adjustable abutment means are mounted. The two conveyors move at the same speed and in the same direction, so that each one of the abutment means, throughout the entire movement, is located in register with one and the same workpiece. A transverse displacement device realises the lateral displacement of the workpieces until such time as the abutment means receive them. The abutment means may be either stepwise or continuoulsy adjustable. For a further stabilisation of the workpieces, there is a rail mounted at the discharge end of the conveyor, so that the end of each workpiece will slide along this rail without being displaced in the transverse direction. |
