Abstract (en)
[origin: EP1314674A2] A method is disclosed for connecting adjacent objects (1) such as paper rolls to each other, the method comprising the step of inserting a bushing (3) through the center bores of at least two adjacent paper rolls. The method is implemented by way of moving the parts of the bushing (3) formed by at least two parts in the bore of the objects relative to each other, whereby the parts are guided by the mating division surfaces (A, B) of the bushings, at least one of the mating surfaces having a spiraling shape, in the longitudinal axis direction of the bushing so that the outer diameter (U) of the bushing increases thus causing the bushing to expand tight in the center bores of the objects (1). The invention also concerns a device for connecting objects (1 ) to each other. <IMAGE>
