• TITLE Method and device for conveying objects in the suspended position.
• the invention relates to a method for conveying objects in the suspended position as well as a device for implementing such a method. Although more particularly intended for the conveying of bottles, it can also be used for all other types of objects, in particular for objects having an elongated dimension with respect to its other dimensions.
• bottle preforms that is to say tubular objects provided with a bottom and an opposite threaded orifice, intended to be transformed into bottles by blowing.
• the bottles are made to swing laterally and / or longitudinally, which interferes with their progression and can cause impacts between bottles when they are close to each other.
• Complete stoppages of a conveyor line can also occur when a bottle swings too wide and locks in its guide rail or with the next bottle.
