Abstract:
A foam cutting machine for operation in a surface cutting mode, comprising:a compression roller of a first diameter and a pattern roller of a second diameter that is at least about 50% greater than the size of said first diameter, each said roller having a roller axis mounted to a corresponding indexing guide on a machine frame for rotation about mutually parallel axes and defining therebetween a gap, the indexing guides extending at an obtuse angle to each other; a cutting edge mounted for cutting material drawn through said gap by rotation of said rollers, said cutting blade being adjustable in a cutting plane towards and away from the rollers; and a drive for driving said compression roller and said pattern roller for rotation; the compression and pattern rollers being positioned on said corresponding indexing guides such that said roller axis of the compression roller is closer to said cutting edge than said roller axis of the pattern roller along a direction parallel to said cutting plane, so that said point of minimum spacing between the rollers is brought closer to said cutting edge.
