The process is used for tempering preforms made of a thermoplastic material; the preforms are to be blow molded. The preforms are provided with a temperature profile along a circumference. The temperature profile is generated by differentially heating strip-shaped regions, which extend in the direction of a longitudinal axis of the preform. A step-by-step tempering for the purpose of temporally sequential thermal conditioning of different regions of the preform is carried out with movement phases and rest phases. A carrier device is rotated by the interactions of a gear and a matching gear for initiating rotational movements. The preform is moved, motionless with regard to the rotational direction, through the tempering zone at least along a portion of the transport path before the start of the engagement of the gear with the matching gear.

Device for tempering preforms and tempering method

A rollbar for an open sports car which extends over the width of the vehicle, having a basic shell body which follows the rollbar shape and consists of molded two-dimensional material with longitudinal ribbings which are alternately raised toward the exterior and interior side of the rollbar. The rollbar shell is integrally formed from a pressed molding of fibrous composite plastic or metallic material and can include stiffening inserts which extend over at least part of the longitudinal extrusion of the shell. An anti-abrasion material can be integrally connected or embedded into the surface of the shell. The rollbar is light weight, optimally designed for individual types of loads and can be integrated into the car body in an esthetically appearing manner.
