Footpath and the girth of pipe crimping.When mechanism stops and mair motor reversely rotates 1/4th circles, the girth of pipe crimping determines the big of tension force
Little, because reel diameter is change during reel stroke, radius girth is also change.Case above causes
FTS system can not accurately determine the numerical value of tension torque, thus can not control tension force well, and then makes fabric easily because of tension force
Excessive and damage, or tension force is too small and causes the most smooth.Additionally, FTS is dedicated motor and fabric, dedicated control system includes
The accessories such as pipe crimping support are all that requirement is higher, so system cost is costly.

Time, steel wire lengthens along with ropewinder reversion.Now, pipe crimping is inverted by the release of the spring torsion in fabric pipe crimping.FSS system is wanted
In asking single minor face to amass and be 12 square meters, length is less than 6M, and shape mainly has linear, trapezoidal, arc, S-shaped etc..
, there is shortcoming as follows in the FSS canopy of the heavens:
(1) FSS tension mechanism is to be produced the energy moment with motor to drawing generation tension force by the deformation of spring.Due to spring
The size and the string diameter of spring, diameter and the number of turns etc. that produce energy have relation, and the deflection of spring is to drive with person's motor
Rotating cycle and become, so the coefficient of tension can not be set accurately.
(2) FSS tension mechanism is to drawing generation tension force by the moment deforming generation energy and motor of spring, due to spring
After producing energy, using the time the longest, spring there will be fatigue makes system tension diminish.
