DISPOSABLE/REUSABLE CORE ADAPTERS

摘要

A core adapter (10; 110) formed as a hollow cylindrical sleeve (12; 112). A plurality of apertures (26; 126) extend through the sleeve, parallel to the sleeve's longitudinal axis (20; 120). A plurality of radial apertures (113) are formed in the sleeve for each longitudinal aperture. Each radial aperture is perpendicular to sleeve's axis and intersects a longitudinal aperture. Studs (14; 114) are provided in each radial aperture, initially recessed beneath the sleeve's outer surface. The sleeve's outside diameter (28; 128) is sized for insertion into a 6-inch inside diameter core (102; 310). The sleeve's inside diameter (30; 130) is the same size as a 3-inch inside diameter core. The adapter is inserted into a 6-inch core until it is flush with the end of the core. Wedge-tipped bars (94; 194) are driven into each of the adapter's longitudinally aligned rows of studs, and against the bottom (18; 118) of each stud, thereby driving the studs perpendicularly away from the sleeve's axis into the core.
