Abstract
Two cooperating spiral conveyors are provided between a transport device having a transport plane and a transport segment. The conveyors are driven in opposite directions and are provided with opposite thread directions. The axes of the spiral conveyors are disposed at the height of the transport plane. The pitch and the thread clearance of peripheral recesses of the spiral conveyors decrease continuously from the transport device to the transport segment. A support surface for a lid is disposed between the two spiral conveyors. At the end contiguous to the transport device, the support surface has the same height as the transport plane, and at the end contiguous to the transport segment, its height is lower by half of the lid diameter.
