Abstract
A pot spinning machine for forming a spinning cop includes a spinning pot onto an interior of which yarn is deposited to form a spinning cake; a yarn guide which deposits the yarn onto the spinning pot to form the spinning cake; a yarn carrier onto which the yarn is rewound from the spinning cake to form the spinning cop; and a lifting member that engages, moves, and positions the yarn carrier with respect to the spinning pot. The yarn guide comprises a yarn passage defined only by the yarn carrier through which the yarn passes in direct exposure to said yarn carrier for deposit in the spinning pot. A method for forming a spinning cop includes depositing yarn onto an interior of a spinning pot of the pot spinning machine to form a spinning cake; and rewinding the spinning cake onto a yarn carrier to form a spinning cop. The step of depositing yarn to form the spinning cake includes guiding the yarn onto the interior of the spinning pot by passing the yarn through a passage defined only by the yarn carrier while moving the yarn carrier relative to the spinning pot.
