<p>[QUOTE="saltysam-1, post: 2353030, member: 23368"]The process to make a curved cut verses a straight cut with paper, requires totally different machines and cutting blades. The stresses put on the paper are also totally different. Straight cuts use a large blade that cuts through the paper at an angle, similar to how you saw through wood but in one stroke. Curved cuts are cause by a die with the proper radius. The pressure comes directly from the top down. This type of cut also puts stresses on the paper from multiple directions which can easily buckle the paper and therefore create more waste and jamming of the equipment. The straight edge blade only puts stress from one direction and that can be countered with blocking guides. Practically no waste. So you would need two machines to complete a bill with rounded corners verses one machine. You double the expense from equipment, manpower, handling, set up and on down to the additional waste of product. That is expensive. Bills that are pulled from use have a lot more wrong with them than just the wear on their corners.[/QUOTE]</p><p><br /></p>
