Festoon apparatus having upper and lower sheave assemblies mounted for vertical movement upon a support column for supply and withdrawal of tire bead material. The upper sheave assembly is supported near the top of the support column by a selectively releasable latch mechanism during normal operation of the festoon apparatus. The lower sheave assembly moves upwardly on the support column during periods when bead material is withdrawn from the festoon faster than it is supplied, and downwardly when the material is supplied faster than it is withdrawn. The lower sheave assembly is connected to a cable which passes through a pneumatic cylinder, mounted upon and parallel to the support column. The cable is connected to a piston within the cylinder. Pressure on opposite sides of the cylinder is maintained substantially equal as the piston moves together with the lower sheave assembly by means of a pilot operated regulator with pneumatic feedback. When the festoon is empty, manual operation of a valve provides pressure to the cylinder, moving the lower sheave assembly upwardly until it contacts the upper sheave assembly and supports the latter independently of the latching mechanism. An operator actuates appropriate switches to release the latch mechanism and the lower sheave assembly is lowered, with the upper sheave assembly supported thereon, by gravity as controlled by operation of the pneumatic cylinder. Both sheave assemblies are then accessible for threading of bead material thereon by an operator standing at floor level. After threading, both sheave assemblies are moved upwardly by the cylinder, the upper assembly is again latched in its upper position and normal operation resumes.
