Independent Machine Co. of Fairfield, NJ has developed its latest system for slitting and traverse winding security strip material as narrow as 1mm. The slitting station with unwind is modular and completely separate from the Smartwinders.
Independent Machine Company is pleased to announce the development of our 2-Position a shaftless center driven turret unwind accommodating maximum 70” diameter supply rolls.
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.

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
Independent Machine Co Fairfield, NJ has become a major producer of slitting and computerized traverse winding equipment to the worldwide Advanced Composites industry.
During the 1980’s Independent developed computerized traverse winding for the paper and film industries and was able to leverage this technology for the development of more advanced systems including composites. By the beginning of the 21st. century Independent had introduced a contract converting service [ICE] utilizing the machinery advancements developed by Independent Machine.
For the past ten years these two separate entities have worked in tandem to develop the latest innovations in slitting & traverse winding thermo set, thermo plastics, glass, etc. The converting operation offers a method of introducing the advantages of computerized spooling to the rapidly changing needs of the composites industry without the capital investment. This provides several advantages to the user; (a) converting can provide immediate product spool supply and (b) converting can become the test bed for whatever machinery will be required when the customer makes the decision to bring the converting operation in-house. This has actually become a main advantage of first contract converting with ICE with a plan for the future acquisition of capital equipment from Independent Machine Co.
The engineering ability of Independent Machine is an invaluable tool for ICE to quickly modify existing converting equipment for whatever the application may require. With more than 40 years’ experience in the development of a wide range of web processing machinery such as cross ply, hot melt coating, calendering laminating, unwind/rewind and slitting systems Independent Machine can easily cross over and use the technology developed for one industry to another.
IMC has developed a new computerized traverse winder for the thread, wire and cable industries.
