A core winding a web of deformable material which is thicker along its margins, particularly knurl-edged webs. The core includes a rigid cylindrical member and a deformable cover supported by the rigid member. First and second detachable end members are adapted for attachment to the ends of the rigid member. The hardness of the end members is harder than the deformable cover such that the knurled margins overlay the end members.

Core for winding a web of deformable material

A core for winding a web of deformable material which is thicker along its margins, particularly knurl-edged webs. The core includes a rigid cylindrical member (24) and a deformable cover (26) supported by the rigid member. First and second detachable end members (18,20) are adapted for attachment to the ends of the rigid member. The hardness of the end members is harder than the deformable cover such that the knurled margins overlay the end members.

Webs are provided with edge knurls whose effective height varies along the length of the web in a predetermined manner.
