The invention relates to primary processing bast fibers, preferably flax, and increases the yield of long fibers obtained by reducing uneven loads on the layer of the processed material due to parallelization strands in the layer. The basis of the utility model tasked improved drum construction scutching machines for processing bast fibers so that in the process of beating during its initial stage to align the magnitude of the forces tensioning individual strands, thus ensuring higher yield of long fiber and improving its obeskostrivaniya. The problem is solved in that in the drum scutching machines for processing bast fibers having a lengthwise conical and cylindrical portions consisting of the shaft, blades and fixed to them podbilnyh gratings according to the invention, on the conical portion of the drum before podbilnymi gratings disposed lattice to parallelize fibrous strands in the processing zone, made in the form of resilient rods in a cantilevered fixed near the shaft and radially spaced with varying pitch along the length of the drum. Using the proposed design scutching drum does not require a significant capital cost, and its implementation can be performed by modernizing existing designs scutching machines.
