Abstract: A method and device to seize the end of a roving, yarn or the like from a cop and carry it to a predetermined position envisages the use of an elongated hollow body wherein several ducts for feeding air or other gas are housed. The mouth of the hollow body is positioned near the end of the roving on the cop, the latter is detached and raised from the cop and subsequently sucked and/or pushed along said hollow body by means of one or more blowing and/or sucking jets. Finally, the hollow body opens to free the roving and is then removed.

Abstract: An endless structure for the continuous transport of a plurality of bobbins is disposed for operative association with one or more textile machines such as, for instance, spinning machines. Each bobbin is marked with a code according to whether the bobbin is empty or wound with sliver, as well as the type and count of the sliver wound thereabout. As the bobbin travels on the endless transport structure the code is read and the wound bobbins are directed to an appropriate textile machine for unwinding. Empty bobbins are removed from the textile machine and carried by the endless transport structure to an exit station. At the exit station, empty bobbins are loaded into a sliver winder for rewinding with sliver. Once wound, the bobbins are marked with a new code and inserted back onto the endless transport structure.
