Slitter/Duplex Rewinder For Holographic & Coated Thin Film

/in /by

The 24” wide slitter with cantilever-supported duplex rewind provides closed loop programmable constant & taper tension throughout the speed range to 1000FPM.

FOR IMMEDIATE RELEASE – Independent Machine Company has developed another in a series of precision custom unwind/ slitters for narrow widths. The 24” wide slitter with cantilever-supported duplex rewind provides closed loop programmable constant & taper tension throughout the speed range to 1000FPM.

The double supported unwind with auto edge guiding accommodates a 32” OD supply roll of thin gauge holographic printed and coated film mounted on an air shaft secured in safety chucks. Adjustable unwind tension is controlled by a pneumatic brake though a load cell feedback system.

The exclusive IMC interchangeable slitting section accommodates razor, score, rotary die and shear assemblies. Edge trim from each side of the web is traverse wound. Entry and exit “S” wrap pull rolls have static dissipation and are the main speed reference. The entry “S” wrap section is direct driven and the exit section is driven through an adjustable clutch to provide tension isolation and adjustable “draw” control during slitting.

The duplex rewind has two flange mounted cantilever – supported 3” rewind differential air shafts with diameter measurement through layon roll position for programmed closed loop tension/taper control. Both rewind shafts have individual static dissipation and pneumatic actuated outboard supports engaged during winding and retracted during roll removal and core replacement. The finished rolls to 30” diameter are automatically moved by a motorized push off device at each position onto a rotating gin pole to simplify roll removal. The gin pole is then rotated away from the rewind and indexed from vertical to horizontal for overwrapping and finished roll removal.

Other features include machine mounted control panel, Allen-Bradley PLC and A-B pendant mounted Touchscreen operator controls.

Quality Converting Equipment

/in /by

It’s been a rough couple of years for builders of web processing machinery but those of us that survived into 2010 are reaping benefits of a slowly emerging international recovery.

The beginning of the year started slowly but by the second quarter capitol equipment plans for coaters, calenders, slitters, unwind & rewind equipment and traverse winders that were put on hold in 2008 seemed to emerge from the shadows at a frantic pace.  Because of industry consolidation, however, equipment manufacturing choices were not as numerous.

The survivors appear to be the companies that relied on continuous machinery improvement and innovation  that set the standard for their industries rather than relying simply on the price benefit. What this may mean is that the outsourcing frenzy to be competitive solely through price may prove to be  a 20th Century model that is not quite as effective in this new, highly competitive  world market.  Goods manufacturers are beginning to  realize maybe quality has to be a larger factor in the cost/benefit equation.

In our own experience we see many more projects from western Europe, that are no doubt also impacted by the lower dollar against their currencies, but also by the need for manufacturing innovation and quality. Our computerized traverse winding systems [Smartwinders™]continue as the world standard for this growing segment of the converting industry that realize the benefit of spooling long lengths of narrow width materials.

The introduction of our Spool-Mate provides a convenient, high quality and cost effective method of unspooling material into a continuous process
