Abstract (en)
[origin: WO9714634A1] The folder/gluer has lip seals (118) associated with each side plate (111) of the conveyor housing (110). These lip seals are slightly lower than the top surface of the feed conveyor belts (120). When the vacuum is applied to the vacuum holes (175), these lip seals do not allow the vacuum acting on the article sides to be bled off to the atmosphere. This results in conveyance far superior to anything known to date.
