Manufacturing automation is no longer a choice but an obligation of companies if they want to remain competitive in the market. There are no major problems with companies engaged in large-scale manufacturing, because the invested funds will return very quickly, which is not case with small-scale manufacturing. In this paper, the automation of the production line for the production of copper couplings will be approached. Couplings are made by stamping a coper strip that needs to be straightened beforehand. The first part of the paper provides an insight into a specific problem in the production of couplings. The technology of stampings and straightening of the strip/sheet is also explained. In the continuation of the work, the design of the straightening device will be approached, so it is of great importance to understand the straightening process itself. In addition to straightening, it is necessary to automate the feeding of tape. Prior to the construction of the device, a brief overview of the already existing devices is given in order to more easily define the direction in which the design should start. The main part of the thesis relates to the design process of the straightener and feeder. The beginning of the design starts with setting the main design tasks and making a list of requirements. The final design solution of the device is reached trough the conceptual design and conception. All design steps are explained to make it clear why the final design solution is as given by the 3D model. Towards the very end of this paper, the elements of the control system are presented and described. It is very interesting that 90 % of the parts are used, ie. that are parts that company already owns and there is no need to buy them. At the end of paper, in conclusion, a review of the implemented project is given and final opinion on given topic is concluded.
