ABSTRACT:
A device for engagement with a moving web to remove curl, fold or crease from an edge thereof. Opposite banks of elongated stationary fins are angularly disposed with respect to the direction of movement of the web and are spaced apart to define a predetermined web passageway therethrough. The edge of the traveling web passes between the banks of fins and cooperative forces produced by the opposing banks of the elongated angularly disposed fins remove curl from the edge of the web as well as removing folds and creases. In a preferred embodiment, the elongated fins have opposite taper at leading and trailing ends to permit proper feeding of a web therebetween and to permit location of the device in close proximity to adjacent web handling equipment. In another preferred embodiment, the two banks of elongated fins are operatively associated under spring tension, whereby adjustment may be made between banks of fins while damage to a web passing therethrough or to the device is substantially alleviated.
