Abstract: A convertible web tension transducer and a roll assembly including two such transducers in which each transducer includes a coupling supported by a pair of resilient beams from a support member through a self-aligning bearing permitting pivotal movement of the coupling relative to the support member in any direction normal to a roll axis of the transducer and the roll assembly and being provided with a pivot pin arrangement to prevent relative rotation of the coupling and support member when a stationary shaft supporting a live roll is supported by the couplings of the transducers, the pivot pin arrangement including a pivot pin which may be omitted from the transducer when a live shaft or roll is supported by the couplings of the two transducers with a consequent requirement for relative rotation of the coupling and support member, about the roll axis, to be permitted.

Abstract: A tension brake or clutch having a quick release torque post providing in a first position, to which it is resiliently biased, torque transmission between a brake or clutch pad and an actuator plate and providing in a second position, to which the post is easily and quickly slid against the resilient bias, disengagement from the brake pad to permit the pad's quick and easy removal and replacement. A latch pin is optionally provided to latch the torque post in the disengaged position.

Abstract: A combined roll/tension transducer for supporting a moving web while sensing the tension thereof. There is a rigid support shaft and a pair of roll support and signal generating assemblies disposed adjacent the respective ends of the shaft. The assemblies each comprise a collar non-movingly attached to the shaft; a pair of resiliently bendable opposed beams carried by the collar and extending therefrom parallel to opposite sides of the shaft; a cylindrical support member disposed over the shaft and carried by the pair of beams, the support member having an axial bore with the shaft passing therethrough which is a clearance fit to the shaft; a ball bearing fit onto the outer periphery of the support member; and, a plurality of strain gauges disposed on the upper and lower surfaces of respective ones of the pair of beams to provide signals at outputs thereof indicating the strain in each of the strain gauges.

Abstract: An improved transducer of a cantilevered beam type wherein a force to be measured is applied perpendicularly to the end of the beam through the joint and the improved joint comprises a self-aligning first roller bearing having an axially aligned center bore and a cylindrical outer surface. A cylindrical inner member is carried by the end of the beam while a cylindrical outer member is provided having cylindrical inner and outer surfaces. The cylindrical inner surface is of a diameter to be a sliding fit about the outer surface of the first roller bearing and has parallel, spaced, inward facing ridges thereon of a spacing greater than the width of the first roller bearing. A biasing device urges the first roller bearing toward a neutral position. A second roller bearing having a center bore with a radius larger than the radius of the cylindrical outer surface of the cylindrical outer member is disposed concentrically thereabout in alignment with the first roller bearing.
