ABSTRACT:
A core for compressed core wound paper products such as toilet tissue and paper toweling is disclosed. The core is selectively cut and scored to form folding tab portions that fold radially inward when the core is in a generally flattened configuration. Upon rerounding of the core to a generally cylindrical configuration, the folding tab portions can be unfolded to form circular arcs conforming to the core inner and outer surfaces. The folding tab portions enable the core to reround to a generally cylindrical configuration that resists reflattening.
