Abstract

A rotary plate is provided for fiber sliver depositing devices, in particular for draw frames and carding machines. The plate includes a spatially curved sliver channel made of a pipe element with two arcs of circles verging directly into each other. The sliver channel of the rotary plate is preferably made of special friction reducing steel. The plate may also include a cover attached to the bottom thereof also formed of the friction reducing material.
