Automatic Core Cutters

There’s always something interesting happening here at Universal. Usually the most interesting activities I get involved with are customer trials or R&D. Both are great because they are good opportunities to showcase the enthusiasm inherent in the culture at Universal.

Sometimes some of the scenes that impress me the most are the quiet ones. A box full of beautifully machines parts, ready for the assembly line. Or the fascinating Solidworks schematics being worked on the studiously focussed atmosphere of the drawing office.

A couple of days ago I walked through the part of the factory where our CCA Automatic Core Cutters are built. All the mechanical fitters, electrical and controls engineers were elsewhere. But on that day, in this quiet section of the factory was the perfect picture of efficiency and productivity - six automatic core cutters, ready for commissioning. I took a photo on my phone and have decided to share it here, on my personal blog. Just out of shot is one of the core cutters that includes the automatic core loader that is proving very popular with customers.

Trim removal on slitters

A trim fan attached to a slitter. As discussed previously on this blog the process of slitting (at its most basic) can be reduced to the one-line description of ' a big roll is loaded on one side of the slitter rewinder, and smaller rolls are loaded off the other side' and that's fine... most of the time. Here comes the example! If a 1000mm wide roll is loaded onto a rewinder and is slit down into rolls that are 212mm wide then four rolls would be produced. If your mental maths is up to scratch you might have noticed that 4x212 does not equal 1000, and that means that from the original / master / jumbo roll there will be roughly 117mm left over. Sometimes this happens because the edges of jumbo rolls are discarded due to damage, print reasons or simply because the material being slit isn't coated all the way to the edges of the roll. So what happens to this waste material? Waste material can be wound onto cores in the same way 'correct' rolls are,

Slitter core alignment using lasers

Lasers and slitters go together like cheese and biscuits, and fitting laser scoring, cutting and perforation devices to slitter rewinders is something that has now become reasonably commonplace here in our factory, but lasers can do a lot more than cut and perforate. We've recently had a huge upsurge in interest in our ' ComputaCore ' laser core alignment system, and because it is such a simple system to control and operate it can be a little bit challenging finding many things to write about it - it's simple and it works very well! But what's in the box? We've made our laser core alignment kit as easy to fit as it is to operate, and to highlight the simplicity of this approach to perfect core alignment we've recently published a post on the subject on our blog here - https://www.universalconvertingequipment.com/laser-core-alignment-whats-in-the-kit-and-how-does-it-work We're planning a new promotional video for our laser core alignment syste

Skymark are using laser to stay head of the competition

The news has just gone public that Skymark Packaging Ltd have bought a Universal X6lp Laser perforation Slitter Rewinder for their facility in Scunthorpe, here in the UK. Skymark have recently been in the news for declaring that their experience of the flexible packaging market is particularly buoyant at the moment. Their reasoning is that following the Brexit vote, a lot of supply chain risk is being mitigated by companies processing more materials here in the UK. In addition to sharing common features with our X6 slitter, the X6lp can also laser perforate and produce easy open scribe lines. The easy open packaging systems are popular with producers who want their products to be consumer-friendly, but to still be able to protect the contents of the packaging.
