Abstract
A winding core useful for winding and storing a nonwoven web or other fabric material includes a main core body and a mechanical entangling mechanism disposed on an outer surface of the core body. The mechanical entangling mechanism ensnares an end of the nonwoven web and holds it in place on the winding core during the initial winding of the web around the core.
Claims27
A combination including a winding core and a fibrous web in the form of a roll, the winding core comprising:
- a main body;
- and
- an entanglement mechanism on an outer surface of the main body;
- the entanglement mechanism being capable of mechanically engaging and holding the web against the core in a peelably releasable fashion;
- the entanglement mechanism located in a region which substantially covers the outer surface of the main body.
A combination including a winding core and a fibrous web on the winding core in the form of a roll, the winding core comprises:
- a main cylindrical body;
- and
- a plurality of prickly protuberances disposed in the main cylindrical body;
- the prickly protuberances located in a region which substantially covers an outer surface of the main cylindrical body.
A combination of a winding core and a fibrous web, comprising:
- a winding core having a main cylindrical body and a mechanical entangling mechanism disposed in an outer surface of the body;
- and
- a fibrous web wrapped around the winding core;
- the mechanical entanglement mechanism substantially covering the outer surface of the body.
