Abstract: An easy and simple transport of cop tubes to a travelling automatic service unit for exchanging wound packages for empty tubes has a conveyor in the form of a flat belt supported by upper slide surfaces of supporting walls fixed onto beams of the machine frame. The walls, together with the belt are inclined to the horizontal plane at an angle of at least 10 degrees, and at most 45 degrees.

Abstract: A portable device for collecting and automatically sorting wound spools from open-end spinning machines is described. The device includes an entry chute that cooperates with the outlet end of a conveyor on the top of the spinning machine for guiding each spool into a wedge-shaped classifying guide, which directs each spool into an auxiliary storage magazine or onto a conveyor in accordance with the overall diameter of the spools. The spools directed to the conveyor are guided in the device onto a second conveyor, which moves in a horizontal path above a movable platform, from which extend a plurality of spool-receiving receptacles. Facilities are associated with the second conveyor for successively receiving classified spools from the first conveyor and for releasing the spools seriatim onto the underlying receptacles.
