Abstract: Drive apparatus for a spinning can (4) effecting a rotational movement about its own axis (a) for depositing textile fibre slivers on spinning preparatory machines. The axis (a) of the can itself rotates about an axis (b) which is fixed relative to the room and which is parallel to the can axis (a). The can (4) is placed and centered on a can table (5) which is rotatably supported in a plate (7), and which is set into rotation by a rotating means (8) and is provided with a driving element (22). The plate (7) is horizontally supported on at least three points and performs a translatory circular movement activated by two cranks (14,15) moving mutually parallel. The drive element (22) of the table (5) is rotatably connected with at least one crank (14 or 15). The translatory circular movement of the plate (7) about the axis (b) is derived from the rotational movement of the can table (5) about its own axis (a).
