Automatic Turret Unwind Splice Sequence

Описание: This video shows an automatic splice sequence of a turret unwind designed to handle extensible substrates at low tensions. The video was taken during a factory acceptance test at New Era in Paterson, NJ. New Era builds a wide variety of turret unwinding equipment, all of which can incorporate a large number of features. This unit featured shaft-less chucking of a range of core sizes, automatic guiding and automatic tension control. The splicing featured a rupture-type serrated cutoff knife appropriate for lap splicing of the materials being run on this converting line.
New Era offers fully automatic flying splice technology at line speeds up to 3000 feet per minute. We can optimize these systems to your process to ensure minimal web length remaining on butt rolls as well as minimize tail lengths on lap splices. Additionally, we can offer tail tape-down on our lap splices to eliminate the concern of a tail being a detriment in downstream processes. Our unwinds can incorporate a variety of cutting knife technologies, allowing us to optimize the knife technology to the substrate being processed. Each automatic turret unwind comes pre-programmed with fully automatic, semi-automatic and manual modes of operation. All of our turret unwinds are provided with automatic tension control and diameter calculation, and can also incorporate features such as shaft-less chucking of varying web widths, new roll edge alignment, automatic guiding, built in pull rolls and tool-less changeover of unwinding modes. Our unwind systems are purpose built for the application and can be cantilever in design for narrow webs, cantilever with an outboard support for wider, heavier bundles which require cantilever unwind and loading, or dual side support for web applications up to 20 feet wide.
