Currently, cross-cutting continuous flow lines with longitudinal or transverse feeding of tree-length are used in the forest industry. The currently used equipment requires improvement or replacement due to the rapid development of automation and increased quality requirements for roundwood assortments. We propose a method for modelling technological movements performed when bucking tree-lengths, using lines with a longitudinal feed as an example; the method is based on matrix transformations of coordinates. The modelling process is preceded by a structural analysis. We suggest that such analysis should be carried out for each structural unit of the bucking line due to the specificity of the subject of labour and equipment created with the special properties of the object of labour (tree-lengths, whole trees) in mind. This will allow us to demonstrate the influence of the properties of the object of labour (tree-lengths, whole trees) on the technological process model.
