Abstract
A yarn recovery device includes a support structure that can be associated upstream or downstream with a yarn feed device, a yarn entry eye and exit eye rigidly connected to the support structure; a drum rotatably associated with the support structure having a seat to accommodate the yarn operationally located between the entry eye and the exit eye; the drum being switchable between a deactivated configuration, in which the seat is substantially aligned with the entry eye and the exit eye and the path of the yarn is not diverted by the drum, and an activated configuration, in which the seat is misaligned in relation to the entry eye and the exit eye and the path of the yarn is diverted by the drum that winds the yarn round itself.

- the yarn recovery device comprising:
- a support structure that can be associated with the yarn feed device;
- said recovery device having a yarn entry and yarn exit associated with said support structure;
- a drum rotatably associated with the support structure having a seat to accommodate the yarn operationally located between said yarn entry and said yarn exit;
