Abstract: A cutting assembly of the type useable for severing a sheet into desired lengths. The assembly includes an elongate track having a slot extending through an upper wall thereof for slidably receiving and retaining a cutter slide therein. The track has upper surface segments that are roughened; preferably with laterally extending grooves spaced along a major portion of the elongate slot. A cutter slide moveable within the slot has a top member overlying the cutting element and extending beyond the element both laterally and in the direction in which the slide is moveable so as to overlie the roughened surface segments of the track. The top member has an extremely smooth stationary lower surface in the regions overlying the roughened track surfaces.
