Working out the dimensions of finished reels sent for slitting is not as easy as it sounds.
For example, a parent reel weighing say 1000 kg, with a diameter of 1000 mm and a width of 1000 mm, with a requirement of rolls at 500 mm in width and 500 mm in diameter would mean four rolls, each weighing 250 kg each. Right? Not so.
Rather than crack one’s head, a user can input these parameters into Dimension 1’s unique Reel Calculator and would come up with an output of eight rolls of 500 mm in diameter and 500 mm in width, and with a weight per roll of 125 kg.
What has to be understood is that paper or film, in a roll, is measured differently to that which is flat. A good comparison is a CD, or DVD, where the circular grooves are smaller in the middle and wider on the outer edge. A roll looked at from the side works similarly.
Hence a length of paper wrapped around a core has to be wrapped more times near the core, as opposed to that on or near the edge.
Dimension 1’s Reel Calculator allows the user to input the weight, diameter, GSM, core diameter, width and length of the parent roll. Working out the final weight, length and final diameter of the finished rolls is as easy as pushing the submit button.
The Reel Calculator is Hosted in Dimension 1’s recently revised website (www.dimension1.com.au) for easy access by users.
Director of Dimension 1, Ashley Goldsbrough, explains that “our upgraded site now allows more interactivity and is more user-friendly.” Quotation and ordering of slitting jobs can now be done online. And, “if the user would rather have us do the reel calculation, that is also okay,” he adds.
