A transport section of a horizontal conveying device used to convey articles, such as liquid containers or bottles, which are moved along in a standing or hanging position on a transport support surface extending in horizontal conveying direction between two guide elements (3, 3'), which are arranged approximately parallel to each other and spaced apart at a distance corresponding to at least the article width or container width, wherein at least one of the two guide elements (3, 3') arranged facing each other is adjustable transverse to the conveying direction in its distance to the other guide element (3, 3') by way of a plurality of adjustment elements (5, 5') anchored to a machine frame or base frame, which adjustment elements (5, 5') are coupled with each other via a common rotary drive and are approximately synchronized, wherein each adjustment element (5, 5') transmits a rotatory impulse of the common rotary drive via one or more transmission steps to a linear adjustment movement of the guide element (3, 3') linked thereto, characterised in that the one or more transmission steps of the adjustment elements in each instance comprise: - at least one input means with external teeth and a first number of teeth n1, said input means being coupled with and rotatably drivable by the rotary drive and - at least one rotating transmission means with external teeth and a second number of teeth n2, said transmission means being arranged downstream of the input means and designed to intermesh comb-like with the input means, wherein the transmission means has a second number of teeth n2 that is at least 1.5 times the number of teeth n1 of the input means; wherein the adjustment elements (5, 5') in each instance have at least one gear rack (8, 8') and the transmission steps each have at least one output means designed as rotary gear wheel, said output means intermeshing for the linear adjustment movement of the gear rack (8, 8') in a comb-like engagement with the gear rack (8, 8'); and wherein the at least one output means designed as a rotary gear wheel and the transmission means are coupled with each other in a non-rotating manner and have a common axis of rotation; wherein the at least one adjustable guide element (3, 3') describes a curved path and is designed to be flexible, wherein, upon a change of the distance of the guide element (3, 3') to the other guide element (3, 3'), the radius of the curved path is adaptable by way of the particular plurality of adjustment elements (5, 5') by an elastic deformation of the flexible guide element (3, 3'); and wherein the linear adjustment movement of the particular adjustment element (5, 5') is transmittable or transmitted, as the case may be, to in each instance one associated support shoe (16, 16') coupled with the guide element (3, 3'), which support shoe (16, 16') in each instance has a contact surface that is brought to abut on the guide element (3, 3') and that at least approximately follows the path of the guide element (3, 3'). - at least one input means with external teeth and a first number of teeth n1, said input means being coupled with and rotatably drivable by the rotary drive and - at least one rotating transmission means with external teeth and a second number of teeth n2, said transmission means being arranged downstream of the input means and designed to intermesh comb-like with the input means,
