Abstract
An edge guide is described that is adapted to restrict lateral movement of a flexible web as the web advances past the guide, the web comprising top and bottom face surfaces and two lateral edge surfaces, the guide comprising (i) a multi-sided body, and (ii) a cavity in one side of the body, the cavity comprising (a) a curved support surface adapted to receive a first lateral edge and to support a portion of the bottom face surface of the web as the web moves laterally into the cavity of and advances past the guide, and (b) a hard stop above, and in one embodiment, continuous with the curved support surface, the stop adapted to engage the first lateral edge of the web and block any further lateral movement of the web over the curved support surface.
