Investigation of Two Cover Stitch Machines in Terms of Process Times, Quality Levels and Their Expenses

Mehmet Kucuk


In an ever-changing market environment, companies should continue developing their own businesses in accordance with the new technologies in order to increase their activities compared to their competitors. In this study, the processing of the twin needle cover stitch (406) in an automatic and non-automatic machine, which are used extensively in most of the clothing products, were compared in terms of process times, quality and cost. As a result of these comparisons made, the time studies taken on the two systems showed that the process times were very close to each other. The difference was due to the repairing process which is handwork (not the machine) for the non-automatic machine. When the cover stitch processes of a basic t-shirt (a hemline and two sleeves) is taking into account, even though the sales price of the automatic machine is higher than the non-automatic one, the calculations showed that the total costs (considering machine sales prices and labor cost) of these two systems come up to 6187th t-shirts (Figure A). For each t-shirt to be processed from this number, it was seen that the total cost of non-automatic machine exceeded the automatic machine's cost.
