Percentage-stretch electric tester
For stay-up embroidery bands and stretching fabrics at large
The measurements are obtained through the descent of a standard carriage group (Kg.4,650) at a speed kept constant by an electric motor (with rechargeable batteries).
The percentage stretching can be tested by locking the embroidery band into the stoppers.
Thanks to the stoppers the test can be carried out directly on the embroidery of fabric roll, without cutting it
