  • Patent number: 5516239
    Abstract: A bottle conveyor has a neck guide formed from opposed lips which are sufficiently thin to be used with bottles having extremely small neck rings and/or extremely short necks and which permit air to be directed onto the bottles from plenum slots positioned directly beneath the neck ring. The lips of the neck guide are preferably formed from a relatively hard, strong, low friction resinous plastic rather than conventional UHMW plastic or metallic lips. The high plenum slots and low friction lip material combine in operation to eliminate the need for a second plenum and thus substantially reduce floor space required by the conveyor as well as the amount of air required for conveyance. The air flowing against the necks of the bottles also provides substantial lift onto the bottles, thus reducing drag and thereby reducing further the amount of air required for conveyance.
