If the direction of the torsion is changed, the movable equipment ll, l2 swivels in the corresponding direction which causes the electric motor to turn the untwisting device I, in the reversed direction.

It is to be understood that without departing from the bounds of the present invention, other modifications and improvements in detail may be found, in the same way as the use of equivalent means may be considered.

I claim:

1. In apparatus for untwisting textile fabrics from rope form into the open condition, a rotatable member in which the fabric rope is charged, means for rotating the same, an opening device, means for passing the fabric rope to said opening device, control means in contact with the fabric rope before it reaches such opening device, which control means are movable by the condition and in the direction of twist of the said fabric rope, and contact means for the regulation of movement of the rotatable member which contact means are operated by the movement of the control means.

2. Apparatus as claimed in claim 1, the control means in contact with the fabric rope being grids between which the said rope passes, such grids being oscillatable together around the fabric rope by the twist contained in the same, and being connected with the contact means for the regulation of movement of the rotatable member to in accordance with the degree and direction of twist of the rope passing between such grids.

3. Apparatus as claimed in claim 1, the control means in contact with the fabric rope being grids between which the said rope passes, such grids being oscillatable together around the fabric rope by the twist contained in the same, and being connected with the contact means for the regulation of movement of the rotatable member to operate on their oscillation such contact means in accordance with the degree and direction of twist of the rope passing between such grids, the grids being connected together and one of them being mounted upon an axis which is parallel to the path of the fabric rope, the other grid being spring-controlled.

4. Apparatus as claimed in claim 1, the control means in contact with the fabric rope being grids between which the said rope passes, such grids being oscillatable together around the fabri'c rope by the twist contained in the same, and being connected with the contact means for the regulation of movement of the rotatable member to operate on their oscillation such contact means in accordance with the degree and direction of twist of the rope passing between such grids, the respective grids having bars.

5. Apparatus for restoring rope fabrics to their open condition, said apparatus comprising controlling members adapted to make contact with the moving fabric rope and movable by and in accordance with the direction of any twist therein, means for rotating the fabric rope to control the direction of rotation of the latter for taking out the twist, and connecting means between the first-mentioned means and the controlling members.
