Abstract
A method for dwelling a portion of a web is disclosed. A web can be conveyed at a first velocity by an apparatus comprising a first traversing guide and a second traversing guide operatively connected in a fixed spatial relationship. The first traversing guide and the second traversing guide can be moveable from a start position in a substantially linear path. The first traversing guide and the second traversing guide can be moved in a first direction at a second velocity equal to about one half the first velocity for a dwell time. One or more processing stations can bond the at least two layers of the web. The first traversing guide and the second traversing guide can be accelerated and decelerated in a second direction opposite the first direction until the first traversing guide and the second traversing guide are returned to the start position in a return time.
