    • Festoon apparatus (16) having upper (28) and lower (34) sheave assemblies mounted for vertical movement upon a support column (40) for supply and withdrawal of tire bead material. The upper sheave assembly (28) is supported near the top of the support column by a selectively releasable latch mechanism (52) during normal operation of the festoon apparatus. The lower sheave assembly (34) moves upwardly on the support column (40) during periods when bead material is withdrawn from the festoon faster than it is supplied, and downwardly when the material is supplied faster than it is withdrawn.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 (34) is connected to a cable (60) which passes through a pneumatic cylinder (56). The upper sheave assembly (28) may be lowered by releasing the latch mechanism (52) and lowering the lower sheave assembly (34) with the upper sheave assembly (28) supported thereon. Both sheave assemblies are then accessible for threading of bead material thereon by an operator standing at floor level.
    • 具有上(28)和下(34)滑轮组件的吊架装置(16),用于在支撑柱(40)上垂直运动,用于提供和退回轮胎胎圈材料。 在滑轮装置的正常操作期间,上滑轮组件(28)通过可选择地释放的闩锁机构(52)被支撑在支撑柱的顶部附近。 在下游滑轮组件(34)在支撑柱(40)上向上移动时,当胎圈材料从其被供给时更快地从吊架中取出,并且当材料被提供得比其被抽出时更快。 下滑轮组件(34)连接到穿过气缸(56)的电缆(60)。 上滑轮组件(28)可以通过释放闩锁机构(52)并使上滑轮组件(28)支撑在其上的下滑轮组件(34)而下降。 然后两个滑轮组件都可以通过站在地板一级的操作员进行,从而使胎圈材料在其上穿线。
