  • Method for aligning and righting preforms by means of centrifugation, and associated device
    Patent number: 10351352
    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.

  • Device for aligning and righting preforms, comprising a bowl centrifuge equipped with means for ejecting misaligned preforms
    Patent number: 10150624
    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.
