Abstract
A method of producing a spinning cop in a pot spinning machine includes depositing yarn from a yarn guide onto an upper location of an interior of a spinning pot of the pot spinning machine to form an upper yarn deposit in the upper location; further depositing yarn from the yarn guide onto an area of the interior of the spinning pot spaced from the upper location to form a spinning cake spaced from the upper yarn deposit; and rewinding the spinning cake onto a tube to form a spinning cop and rewinding the upper yarn deposit onto the tube to form a top winding. Yarn forming the upper yarn deposit has a coarser yarn size than the yarn forming the spinning cake. During yarn deposit to form the upper yarn deposit the yarn guide is moved in one direction without traversing movement, and during yarn deposit to form the spinning cake the yarn guide is moved in one direction with traversing movement. Yarn windings are placed in parallel relation in the upper yarn deposit.
