Abstract

A temperature adjustment device (2) for thermally conditioning preforms (10) made of a thermoplastic material for subsequent molding including a transport device based on the rotary principle for transporting the preforms along a transport path that has at least one section with two adjacent transport lanes (32, 34) for transporting the preforms in two adjacent rows. Heating elements (36) are arranged between the transport lanes for heating the preforms. Each heating element acts on preforms in both transport lanes. At least one compensation device (22, 22′, 23, 24) for compensating for temperature differences between the preforms is assigned to the two transport lanes, which exclusively or more strongly acts on preforms in one of the two transport lanes for adjusting their temperature. Also, a container manufacturing machine (1) for manufacturing containers (12) from preforms that includes a temperature adjustment device.
