1. A device for facilitating the passage of connectors joining elements of a flexible member passing round a rotary member, the device comprising: a double shoe defining a recess whose shape and dimensions are suited to those of the connector, the shoe being normally disengaged from the rotary member and in an inoperative position between the upstream and downstream portions of the flexible member; coupling means operable to cause said shoe to rotate with the rotary member; control means for operating said coupling means; a detector situated adjacent the upstream portion of the flexible member and adapted to energise said control means when a connector passes; and means for deenergising said coupling means when said shoe lies between the two said portions of the flexible member.
2. A device as claimed in claim 1, wherein said rotary member is a body of revolution and the inner surface of said shoe conforms to the peripheral surface of the body of revolution.
3. A device as claimed in claim 1, comprising means for clamping rotational movement of said shoe when it is disengaged from the rotary member and before it arrives at said inoperative position.
4. A device as claimed in claim 1, comprising means for clamping said double shoe in said inoperative position.
5. A device as claimed in claim 1, wherein said shoe is mounted on support means including at least one member rotatably mounted coaxially of said rotary member, said shoE being spaced from the periphery of the rotary member.
6. A device as claimed in claim 1, wherein said shoe is guided radially on at least one support member rotatably mounted coaxially of said rotary member, said shoe being movable radially to bear on the periphery of the rotary member.
7. A device as claimed in claim 6, including progressive coupling means coaxial with said rotary member and operable to couple the support member to the rotary member for rotation therewith.
8. A device as claimed in claim 1, including force generating means operable to generate a force to cause said shoe to bear on the periphery of said rotary member.
9. A device as claimed in claim 7, wherein the shoe is mounted for radial movement on a carriage which is guided relative to the rotary member and which carries driving means operable for applying the shoe to the periphery of the rotary member.
10. A device as claimed in claim 7, including a cradle on which the shoe rests when in the inoperative position, and electromagnet means operable to apply the shoe to the periphery of the rotary member.
