The roller option is made for highly exposed to wind installations, or those which needs a daily dissasembling. This option adds the possibility to roll the sail on itself in less than a minute.
The sail is composed of a reinforcement on the sail along the winding axis and the winding system (swivel on one side, pulley on the other and maneuvering rope on the other).
A winding sail requires different attachments from a standard sail. They are essential to the proper functioning and viability of the system.
The rotation of the sail will only occur if the winding axis is properly tense and straight. Failing this, the sail may not roll up.

1. Selection of reel axis
For triangular sails, the winding axis is one of the sides; for quadrilateral sails, it is one of the diagonals.
However, all these axes cannot always be chosen because the winding of the sail must be done correctly:
ba careful with the rolling axis : it shouldn't be on the wall side because the cranked pulley would rub on it and be hindered in its operation.
If possible, it is preferable to place the reel between two walls (or a wall and a mast) rather than between two masts.
2. Choosing the Position of the Maneuvering Rope
The rope of maneuver is the rope allowing to use the retractor. It is located at one of the two ends of the winding axis.
If your installation has walls and masts, it is the best to place the maneuvering rope (with toothed pulley) on a wall.
Without this constraint, we advise you to place it where it will be more convenient for you to use it on a daily basis.
To be noted : for the other fixture points, no changes.
