Slitter Man

Web guiding is a term describing the method used to correct badly wound rolls or material and is used on slitters and salvage winders .  A sensor looks at material (web) running through a machine and sends a signal to a device that moves parts of the machine to correct the badly wound roll.  Putting it at its most basic web guiding systems allow you to load a roll with a bad edge profile (I.E. not flat) onto a machine rewind it so that it has a flat edge profile. Guider eyes (sensors) read the edge of the web, a line on the web or a 'broken' line printed on a roll of material.  If the web guiding system 'sees' the web move left it will move the web to the right so that as it winds up on the rewind end of the slitter / doctor machine the edge of the final roll will be flat. Many older web guiders move the winding web using hydraulic or pneumatic (air) methods, but hydraulics can leak oil onto the web and pneumatics tend to have slow response times unsuitable to f...

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 . Find out more about our web guiding systems...
