Abstract
A device is disclosed for pulling the web backward through a thermal print station between prints. A web advance mechanism is adapted to move web in opposed forward and reverse directions past the print station. A core upon which a web supply roll is spiral wound with an end of the web extending from the roll to the print station rests on a support having a high friction inclined surface. The inclined surface is oriented such that (i) advancement of the web past the print station in the forward direction tensions the web resulting in rotation of the core such that it climbs up the inclined surface and (ii) advancement of the web past the print station in the reverse direction causes the tension in the web to relax, resulting in rotation of the core by gravity such that it rolls down the inclined surface, whereby slack in the web is taken up by the roll.
