Variable Minimum Trim Width



When breaking out 4mm glass, on a long cut of 2000mm or more, most cutters require a minimum trim width of about 12mm to help avoid the cut running off.  On a cut of 300mm or less however, most cutters can cope with a trim cut of only 6mm.  To take advantage of this fact, Trimloss can be given those four numbers, 2000, 12, 300, 6 to force the minimum trim cut to be increased pro rata between 6 and 12 according to the length of the cut.  It is believed that this feature is unique to Trimloss.  A counter argument often put up by competitors, is that this feature is impractical, or unnecessary.  Our answer to that is that an estimated 20 million sealed units have been made this way with Trimloss, producing the lowest possible waste and without any problems.  





For thicker glasses, the minimum trim widths will of course be set up with larger numbers.  The numbers can also be varied, so that a less skilled cutter can be given slightly more generous trims to help him cope until he is more experienced.  The fact that the minimum trim is variable can often make a considerable difference to the material waste.  Variable minimum trim width is just one more utilisation of mathematical decision theory in Trimloss.  






This feature is particularly applicable to glass, so many optimisers designed by academics who are often totally lacking in glass production experience, are totally devoid of such practical and necessary features.  If these optimisers do have a minimum break out dimension, it will usually be of a fixed minimum width and not have the variable minimum figures of Trimloss.
