Slitter Man

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...

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...
