Abstract
A rail for a machine carriage has an elongate base plate and a pair of spaced supporting walls extending along and rising obliquely from the base plate and converging toward each other in a direction away from the base plate. A first lateral carriage track is located on top of and extends along one of the supporting walls, while a second lateral carriage track is located on top of and extends along the other of the supporting walls and in parallel to the first track. An elongate top plate extends between the first and second lateral carriage tracks and is spaced from the base plate. The base plate, pair of supporting walls, first and second tracks and top plate are integral with each other and encompass an elongate hollow space extending through the rail. Apparatus for supporting and guiding a cutting machine, a machine carriage, and a method of making a machine carriage are also disclosed.
