Slitter web guiding and tea.

Web-guiding is in principle very simple indeed, in fact I'm going to prove it by narrowing it down to just three steps:

The sensor notices the web move
A signal is sent to the actuator to tell it to move the web to compensate
The operator takes another sip of tea and continues to look smug

In reality the web guiding systems we build are very clever indeed, but as with all our systems our slitter guider systems are very user-friendly; once a web guider is fitted there's almost no training needed, and very little operator input is needed.

Web guider systems are predominantly installed on slitters and salvage rewinders.

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, ...

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.

Winding onto 6" cores on a slitter with 3" shafts

A (used) 6" differential ball chuck designed to fit a 60mm rewind shaft (once the 3" chucks have been removed!) I sometimes use this personal blog of mine to talk about the basics of slitting and rewinding, with the content partly led by thinking back to the questions I had when I first started working in the converting machinery industry. One of the first questions I had was 'how on earth can slitter rewinders with 3" rewind shafts be used for winding onto 6" cores?' A lot of converters and labellers / packaging companies regularly switch between winding onto 3" (76mm) and 6" (152mm) cores, which is one of the reasons we designed our Automatic Core Cutter to change between core sizes in under thirty seconds. But what do companies who predominantly wind onto 3" cores do when they need to wind onto 6" cores? The answer is actually quite simple - they remove the 3" ball chucks and slide on 6" core chucks! There are of...
