An apparatus (10) and method for rewinding large rolls of paper (12) into smaller rolls (22), such as bathroom tissue rolls. The rewinder (10) includes three rolls forming a winding cradle (24) and winding control fingers (30) operating adjacent to and in the winding cradle. Upper and lower winding rolls (16 and 20) are spaced apart for enough to allow a core (28) to be introduced between them by the winding control fingers (30). A rider roll (26) moves relative to the winding rolls (16 and 20) to control the diameter of paper (12) being wound. The lower winding roll (20) is preferably equipped with two sets of winding control fingers (30) which can orbit around the roll (20) and introduce the core (28) between the winding rolls (16 and 20), separate the web (12), guide the web (12) around the core (28) and remove the completed log (22) from the winding cradle (24). Each of a plurality of winding control fingers (30) is equipped with a core insert finger and a web separation finger so that each winding control finger can independently receive, transport and deposit a core (28) in preparation for the winding process.
