Traveling cutter assembly

A cutting assembly of the type useable for severing a sheet into desired lengths, said assembly including:

• an elongate track having upper wall sections terminating in spaced-apart inner surfaces defining an elongate slot, said upper wall sections having roughened top surfaces;
• a cutter slide moveable in the slot and including a cutting element having a cutting edge adapted to engage and severe the sheet when said sheet is positioned across the slot and in overlying relationship with the roughened top track surfaces, said cutter slide including a top member overlying the cutting edge and extending laterally beyond the cutting element in overlying relationship with the roughened track surfaces, said top member having an extremely smooth stationary lower surface in regions overlying the roughened track surfaces, said cutter slide being moveable in the track with the smooth lower surface of the top member in sliding engagement with the sheet and pressing said sheet into engagement with the roughened top track surfaces to prevent relative sliding movement between the sheet and the track as the cutter slide is being moved to cut said sheet.
