Abstract: A device and method for aligning preforms in a row and righting same, the method being intended for use with axisymmetric preforms having an annular supporting face. The method includes a first step of discharging the preforms in bulk onto a rotating horizontal platen; a second step of aligning the preforms against a fixed peripheral rail by way of the centrifugal force produced by the rotation of the rotating platen; a third step of successively righting the aligned preforms by tilting the preform bodies, performed under the annular supporting face. During the second alignment step, the main axis of the preforms is oriented essentially tangentially to the direction of movement.

Abstract: Disclosed is a device for aligning preforms in a row and righting same, the device including a bowl centrifuge formed by: a horizontal circular platen rotating about a vertical axis; a fixed peripheral rail; at least a first angular sector for aligning the preforms against the rail; and at least a second angular sector for righting the preforms. The device includes a unit for actively ejecting incorrectly aligned preforms from the row of correctly aligned and righted preforms.

Abstract: Disclosed is a device for transporting plastic-container preforms, the device including an endless circulating element having an outer surface and being capable of moving the preforms along a path by rubbing against the preforms, the device including a stationary mounting defining a planar bearing surface for the preforms, the circulating element having a series of brushes which extend projecting from the outer surface, capable of engaging with the preforms in order to move same by rubbing.
