1) The thickness of a layer is measured using an engineer slide calliper with the pressure of jaws of about 10 N.
2) The values of tension are only orientative ones and it is necessary to adapt especially the tension of the shuttle thread according to the stiffness
of the material. An excessive tension of the threads when sewing soft materials causes material wrinkling.
3) There are in use various types of feeders with the purpose of avoiding imprinting the teeth in the lining leather. Otherwise, it is possible to use
any feeder.
