ABSTRACT:
Apparatus for supporting the core of a reel of convoluted paper in a winding machine has two trunnions which extend into the end portions of the core from opposite ends of the reel and are surrounded by ring-shaped stops which are normally closely adjacent to the respective end faces of the reel therebetween. The trunnions and the respective stops are movable axially toward and away from the core and each trunnion is surrounded by a ring-shaped sensor which is biased against the respective end face of the reel so that the distance between the sensor and the corresponding stop denotes the width of the gap between the respective end face of the reel and the corresponding stop. Each sensor is connected with a discrete ring-shaped cam by several pins which extend through the corresponding stop and each cam is tracked by one arm of a lever another arm of which can actuate a signal generating device when the width of the gap between the stop and the corresponding end face of the two trunnions exceeds a preselected value. The signal generating device can generate a visible and/or audible signal and/or arrest the prime mover which winds the web from or onto the reel between the two stops.
