Abstract
The invention relates to a process and an apparatus for producing veneer strips, chipped wood or the like, individual pieces of wood being joined together, with grains parallel, to form a group and then a multiplicity of such groups being arranged one behind the other, with grains parallel, to form a closely packed line, whereupon this line is then fed in its longitudinal direction, transverse to the wood-grain direction, to a chipping tool. In order, during the chipping operation, largely to prevent the accumulation of coarse chips, it is proposed according to the invention that the leading group conveyed up against the chipping tool is subjected, via the following group butting against it, to a longitudinal compressive force which acts in the longitudinal direction of the line, which exceeds the relative cutting force to which the leading group is subjected by the chipping tool, and which is largely absorbed by the leading group, which, by way of its advancement speed being braked, acts as an abutment.
