Abstract

A method for randomly interchanging up to four pairs of side framing gates at a framing station of a vehicle for randomly interchanging up to four pairs of side framing gates at a framing station of a vehicle assembly line while maintaining a predetermined build cycle time interval of the assembly line. The method includes positioning first and second carousels on opposite sides of the assembly line upstream of the framing station and third and fourth carousels on opposite sides of the production line downstream of the framing station. The method further includes providing a first linear track structure extending from the first carousel to a first side of the framing station, a second linear track structure extending from the second carousel to a second, opposite side of the framing station, a third linear track structure extending from the third carousel to the first side of the framing station, a third linear track structure extending from the third carousel to the first side of the framing station, and a fourth linear track structure extending from the fourth carousel to the second side of the framing station. The carousel are provided with at least two sides, possibly three sides, four sides or more, each side capable of receiving a framing gate. The method includes randomly interchanging framing gates positioned at the framing station by a combination of rotary movements of the carousels and linear movements of framing gates along the linear track structures.
