The application of eyelets can be made both in footwear, and in clothing and accessories. The washers, are complements of metal eyelets, and are responsible for giving support and finishing to the application of the eyelets, since the part in which this component will be fixed must be drilled. The use of the ruin depends on the function of the eyelets. In cases where it is only decorative or if the piece has forage covering the back of the eyelets, the use of the shroud is dismissed. However, if the eyelets are the passage of a cord or wires for lashing, for example, the use of the shroud is indispensable. To apply eyelets with shroud, the most indicated is the use of the balancim, a pressure instrument, which adapts to the size of each type of eyelets, through the exchange of the pressure matrices. This equipment has a very simple mechanic, consisting of a lever and the space for fixing the dies. To apply your eyelets, you need the exact matrix of the size of the eyelets, in addition to the previously perforated fabric. This drilling should also have the exact size of the metal that will be fixed. After fitting into the balancim the upper and lower matrices, position the eyelets in the lower matrix, disposing the fabric on it, fitting the washer over the fabric and with the upper matrix apply the pressure through the lever. All right, you already have the eyelets with the ruin fixed your piece! Source: West Armarinhos
