Cut to length

Recently I sold a small used slitter to a company with a very simple product process - they buy in big rolls of material and then use a slitter to cut to length.  Unlike most of the cutting machines we sell this customer didn't need a machine that could slit rolls of material down into narrower rolls; all they needed to do was to load a master / parent roll and cut it to length.

But what does it mean? If I was pushed to condense the meaning of 'slitting' into a single sentence (which I guess is the very point of this blog post) then I would have to say: "Slitting is the process of making a slit (cut)." As intimated above, to me slitting in the process of loading
