ABSTRACT:
A vibration damping liner adapted to pass through a relatively small diameter end of a tubular shaft for accommodation in a relatively large diameter section of such shaft, the liner being formed of a plurality of coaxial, helically wound paperboard strips forming inner and outer layers. The confronting edges of adjacent convolutions of each layer are coplanar and unjoined, and the confronting edges of the convolutions of all but one of such layers register with one another. The paperboard strip forming the one layer bridges the confronting edges of the adjacent convolutions of the other layers and is adhesively secured to that layer adjacent such one layer. Such one layer has less resistance to rupture than any of the other layers.
