<p><span style="font-size:14px;"><span style="font-family: times new roman,times,serif;">This machine tests slide (zip) fasteners and complies with SATRA TM50:1992, Method 1. It tests up to and including three fasteners simultaneously by repeatedly opening and closing them until either the fasteners fail or the number of preset cycles is reached.</span></span></p>

Horizontal loads are applied to the fasteners by two horizontal clamps and load masses.</span></span></p>

The two horizontal clamps are fixed to the fasteners, opposite and equal forces are applied to these clamps by stainless steel masses.</span></span></p>

<p><span style="font-size:14px;"><span style="font-family: times new roman,times,serif;">If a fastener fails, the drive mechanism will stop actuating that particular fastener, but will continue operating other fasteners. The mechanism is easily reset when preparing the machine for a test run.</span></span></p>
