    • A tracking assembly (10) for tracking belts (12, 52) and webs comprises a support frame (20) which is adapted to be mounted below a travelling belt or web. A straight or angled support shaft (30) is pivotally mounted at its centre via a post (32) which is rotatable within bush (26, 56) on the support frame. A selected arc of rotation of the post within the bush (26, 56) is determined by an adjustable limit stop arrangement which can take the form of a pair of grub screws. A roller is mounted onto each end of the shaft (30). The two rollers (36, 50) have tapered ends (38, 54). When the belt or web travels off centre it will come into contact with the tapered end of the roller on the side to which the belt has moved. This will cause the shaft to pivot about a vertical axis of the post (32) and thereby steer the belt back to a central position.
    • 用于跟踪传送带(12,52)和幅材的跟踪组件(10)包括适于安装在传送带或幅材下方的支撑框架(20)。 直的或成角度的支撑轴(30)通过可在支撑框架上的衬套(26,56)内旋转的柱(32)在其中心枢转地安装。 柱体(26,56)内的柱体的选定的旋转弧由可调节的限位挡块装置确定,其可以采用一对平头螺钉的形式。 滚轴安装在轴(30)的每个端部上。 两个滚轮(36,50)具有锥形端部(38,54)。 当传送带或卷筒纸离开中心时,它将与传送带一侧的滚筒的锥形端接触。 这将导致轴围绕立柱(32)的竖直轴线枢转,从而将带转向回到中心位置。
