Measuring Range: 0 - 99999
Folding Angle: 135+/-20, Folding Frequency: 175+/-10 times/min.
Folding Head Width: 9+/-1mm; Folding Radius: 0.38+/-0.02mm.
The spring tension: 4.91N~14.72N, when every 9.81N tension is added, the compression of spring is 17 mm reduced at least.
The clearances between folding ports: 0.25, 0.50, 0.75 and 1.00mm (four ranges)
The tension change due to the eccentric rotating of clamping folding head: Should not be larger than 0.343N
