Slitter Man

When you get right down to the gritty details of cardboard cores you'll find that no two core suppliers are quite the same, and when bought in bulk no two parent / master cores are quite the same length.  As your freshly purchased cores come off the transport and into your life you'll find the lengths in the batch are very similar, but they are infrequently all  exactly the same size. The variations in core lengths will often be very small, but when you're as focussed on minimising waste when cutting cores as you are focussed on cutting accurate core lengths then knowing exactly how long your parent cores are is crucial.  You could have your operator measure every core as it comes off the pallet, but that would be time consuming, and with the best will in the world it would probably also be inaccurate. Core cutter auto-trim Our CCA Automatic Core Cutters solves the problem of irregular sized parent cores by having a switch-able 'auto-trim' function. ...

A lot of companies go to great lengths to try and minimise the amount of waste they generate, which makes sense as far as economics and environmental awareness, but sometimes waste cannot be avoided. The video below shows a trim winder that was a part of a l arge slitter we recently built for a regular customer of ours.  This slitter rewinder was designed to convert large rolls of metallized polyester, which is supplied on rolls that are not coated the full width of the web, so a trim needs to be cut off during the winding / slitting process.  Some customers wind trim waste material onto cores on the rewind shafts, and some let narrow trims fall to the floor, but while both options are workable both can be problematic for operators and potentially damaging to materials.
