摘要

The invention provides a method and apparatus for testing the chew-out strength of paperboard cores. The apparatus of the invention includes a clamping element (20) for clamping a tubular core (40) to prevent rotation thereof; a splined chuck element (18) in the form of an axially tapered member having a plurality of circumferentially distributed splines (34) for insertion into one end face (38) of the core (40); and a means (14, 22) for applying increasing torque at a controlled rate to the splined chuck element (18). A measuring means (76) measures the torque applied to the splined chuck element (18). In operation, increasing amounts of torque are applied by the torquing means (14, 22) until the splined chuck element (18) shears the end face (38) of the tube (40) resulting in chew-out of the core (40). The maximum torque force applied to the splined chuck element (18) provides an accurate indication of the chew-out strength of the core (40).
