Abstract
According to its execution structure, the technological sewing operation consists of support-hand suboperations: taking, putting together, positioning, suboperations during sewing breaks and laying off as well as the technological machine-manual suboperation of sewing. In the paper an overview of possible individual suboperations contained in the technological sewing operation and perform of the technological suboperation of sewing are given. Within the technological suboperation of sewing the methods of guiding the work piece in the sewing process, various methods of seam bar tacking, use of auxiliary devices, suboperations during sewing breaks, various methods of cutting of the thread regarding the technical equipment of the sewing machines, seam properties, and level of worker training were developed. By systematic exploration of possible work methods, their standardization and elaboration to the level of basic motions using MTM (Method Time Measurement) system, standard logic sets of basic motions have been established, which can be used to determine the optimal work method which enables the determination of real norms and the reduction of workers workload.
