Traction-Torsion

Watchstrap ageing

This device enables accelerated ageing of watchstrap with or without watch head. Cycles are composed of traction, compression, torsion, alone or combined. Equipment is run with a special software that allows the user to create its own testing cycles.

With the series of available supports, several applications are possible.

  • simulation of leather/rubber watchstrap wearing (tongue buckle)
  • simulation of steel watchstrap wearing (folding buckle)
  • tightening pliers for samples
  • a set support/pliers.

 

It is possible to adjust the temperature of working area in order to make accelerated ageings in conditions as close as possible to reality.

In case of rupture of the aged element, the device detects it and puts an end to the ageing cycle. The user can know the rupture value.

Traction and compression are applied with a pneumatic cylinder. Torsion is made by a motor. During the test, a sensor enables to record the torque value according to angle.

Two possible operational modes:

  • by angle: torsion defined by angular values, and following of torque evolution according to angle.
  • by torque: torsion defined by a torque (Nm), and following of angle evolution according to torque.
