    In this work, a machine is designed and built, proposed by the company that makes footwear, to tighten leather uppers and evaluate defects. According to the evaluating operator, the capelladas will be rejected or accepted for the next process in the footwear production line. The company states that sometimes the capelladas fail in the process of assembly of tips and are discarded, meaning great waste, so the purpose of this machine is to avoid carrying the entire process of sewing and assembling parts checking them just after the punching. In the province of Tungurahua, footwear production is 65% and 80% leather produced in the country according to CALTU (National Chamber of Footwear), is a high figure, therefore, the company wants to improve its production techniques with less waste. By research, analysis, observation, a solution was obtained for the design, where the evaluation process resembles the process of assembling tips on the footwear, which has the cost of clamps and a tensor similar to the last, the calculations of the pistons start from the air consumption of the riding machine. The materials that were assigned to the plates are A36 steel, the AISI 1020 pins, for the axles is AISI 1018 transmission steel, structural tubes for the base, pistons were used with the calculated measurements, springs, bearings, and other elements electropneumatic The machine was built in the company "Mecánica Balladares", who provided their tools and knowledge of the workshop. In this work are plans, operation and maintenance manual, necessary to understand the mechanism and operation.
