ABSTRACT:
A skate for an end cutter for cutting sheet material such as cloth as the sheet material lies on a supporting surface having opposite sides, the end cutter comprising an elongated track extending across the supporting surface between the sides and having a longitudinal axis, an exposed surface over which the sheet material lies during cutting thereof, a slot extending along the length thereof and a guide surface spaced from the exposed surface facing the slot and extending along the track in a plane substantially parallel to the longitudinal axis thereof. The skate is elongated, slides along the track, and has an operative surface facing the guide surface of the track. A bracket extends from the skate through the slot in the track member, and a blade is carried by the bracket and extends into the slot for cutting sheet material lying on the exposed surface of the track as the skate slide therealong. In accordance with the present invention there is provided at least one movable bearing mounted in the skate on the operative surface thereof for providing bearing contact between the skate and the guide surface of the track as the skate slides along the track. As a result of provision of the movable bearing, friction between the skate and the track is reduced significantly and wear life of the skate and the track is increased significantly.
