ABSTRACT:
A web guiding device for directing sheet material from a supply roll into a processing machine along a predetermined track in a manner that corrects for tracking errors caused by side edge-to-side edge variations in the force needed to draw the sheet material from the supply roll. The web guiding device includes a support frame that retains the supply roll in a manner that enables the supply roll to freely rotate about its mid-axis as the sheet material is drawn from the supply roll. The support structure is pivotably mounted to a bracket structure that couples the support structure to the processing machine. At least one guide element is provided on the bracket structure for orienting the sheet material onto the predetermined track prior to the sheet material being received by the processing machine. The support frame and the supply roll are canted when a side edge-to-side edge variation is experienced in the force needed to draw the sheet material from the supply roll. The canting of the supply structure at least partially compensates for the side edge-to-side edge force variations experienced, thereby helping to maintain the sheet material on the predetermined track.
