Abstract
A double-wound center-feed roll is disclosed which is formed from at least two webs each having lines of weakness which allow the webs to be separated into a plurality of sheets. The lines of weakness of one web are offset from those of the other such that in use the sheets can be dispensed singly from alternate webs. A first portion of the webs at the center of the roll is lightly bonded together while a second portion of the webs on the outside of the roll remains unbonded. The center-feed roll of the present invention reduces the occurrence of both web orientation reversal and streaming dispensing problems.
