<p>Attachment consists of elements whose thickness is less than the thickness of the ends of the belt to be connected to each other. Specifically, the connection comprises a row of eyelets fixed at each end of the belt made from the longitudinal wires, an oval metal wire spiral and two hinge pins. The outer diameter of the spiral is smaller than the thickness of the ends to be connected and is maximally 6.5 and minimally 3.5 mm. whilst the thickness of the spiral wire is max. 25% and min. 15% of the outer diameter of the spiral, i.e. averaging 0.8 mm.</p> |
