Abstract
The device includes several rails supported by a frame (17) which form a kind of tunnel for the end of the preforms, on the neck (21) side. The tunnel is twisted and the two rails (12) and (13) which act as a guidance under the neck have a separation which is constant between the entrance (4) and the exit (5) of the tunnel in order to convey diverse and varying preforms. One of the rails, the rail (12), is straight and the other rail, the rail (13), is curved, this curved rail (13) having a profile created in accordance with the type of preform to be conveyed. The straight rail (12) corresponds to the edge of a guide (15) in the form of a simple flat which is fixed to the frame (17), and the curved rail (13) also corresponds to the edge of a guide (16) in the form of a simple flat which is also fixed suitably to the said frame (17).
