Abstract
Cradle for a twisting machine with a reel spindle and friction engaging means to engage a reel mounted upon the spindle. The friction engaging means faces the free end of the spindle and is movable axially away from the free end against a resilient means. A means is provided to urge the reel against the engaging means. In a practical structure, the friction engaging means is annular.
Claims6
A cradle for a twisting machine comprising
- a reel spindle for supporting a reel of filamentary material in a reel support position upon the spindle,
- the spindle rotatably mounted upon a support and having a free end,
- an annular braking member surrounding and secured to the spindle,
- means to apply a braking force to the braking member and thus to the spindle,
- friction engaging means rotatable together with and about the axis of the spindle, for frictional engagement with the reel, said friction engaging means having a friction surface facing towards the free end of the spindle, and
- resiliently compressive means to urge the friction surface towards the free end of the spindle, and
- means for urging a reel when mounted upon the spindle against the friction surface
- to urge the friction engaging means against the resiliently compressive means
- to positively drivably couple the reel with the spindle and the braking member.
