A transport section of a horizontal conveyor device for conveying articles moved along in a standing or hanging position on a transport support surface extending in a horizontal conveying direction between two guide elements arranged approximately in parallel to each other and spaced from each other at a distance corresponding to at least the article or container width. At least one of the two guide elements arranged facing each other is adjustable in its distance to the other of the guide elements and transverse to the conveying direction via several adjustment elements attached to a machine frame or base frame. The adjustment elements are coupled with each other via a common rotary drive and are approximately synchronized and each adjustment element transmits a rotatory drive of the common rotary drive via one or more transmissions to a linear adjustment movement of the guide element linked to it.
