Energy savings that stick like glue.

Even if you're new to the world of hot melt adhesives and the machinery that is used to coat and laminate materials you could probably guess that the use of the word 'hot' in 'hot melt adhesives' denotes high energy usage. While it's true that in bringing adhesives up to a temperature that they can be used for precise coating a fair amount of energy is consumed, it doesn't have to be as much energy as it used to be.

When we (Universal Converting Equipment) build hot melt adhesive coating and laminating equipment (or add coating capabilities to our slitter machines) we recommend our customers use ITW Dynatec adhesive supply units, these are supplied by our sister company Universal Adhesives Limited in Daventry (affectionately known to us as 'Dav'). The new range of ITW's 'Dynamelt' supply systems have been designed with a focus on reducing energy usage, which fits in perfectly with the work we have been putting in to actively reduce the amount of energy required to run all of the machinery that we build here in Ipswich.

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, ...

We need to talk about how you're handling this...

At the risk of sounding like I'm marketing for them instead of Universal I'd like to mention Package Print Worldwide ( @PackPrintWorld ) again. We contributed to the safe materials handling article in the new issue of Package Print Worldwide, with particular focus given to our roll handling trolley . We have recently expanded the range of material handling attachments for the trolley and have seen the number of enquiries rise considerably. Sadly safety is a subject that is sometimes (thankfully only rarely) overlooked by some companies, and when it comes to safe roll handling the risk of personal injury is one that is easy to minimise with the correct equipment. We have priced our materials handling equipment at a level that should be easily affordable to all, so there's no excuse for lax safety!

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...
