Unwinds

New Era manufactures a wide variety of unwinding equipment for web converting applications. Our systems range from single position units to multi-spindle unwinds, can handle web widths from .5″ wide up to 20 feet wide and range in line speeds from 3000 fpm down to a few inches per minute. Our designs are custom implemented for your exact web materials and process constraints, providing you with a purpose built unwinding solution. New Era has multiple patents associated with unwinding, including an automatic, on-the-fly butt splicing system.

Turret Unwinds

Turret Unwinds

New Era builds a wide variety of turret unwinding equipment, all of which can incorporate a large number of features. Our manual cut and splice turrets feature a range of different splice table setups to allow lap splicing, butt splicing or zero tail lap splices. These units can be incorporated with accumulators so as not to stop the process while splices are being made. Additionally, we can automate the splice sequence to facilitate the making of both lap and butt splices at zero speed. Our more sophisticated systems offer 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. Our unwinds can incorporate a variety of cutting knife technologies, allowing us to optimize the knife technology to your substrates. 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.




Single Position Unwinds

Single Position Unwinds

For customers operating roll to roll, New Era offers single position let off stands. These units can be incorporated with accumulators so as not to stop the process while splices are being made. Our unwind equipment can be provided with splice tables, allowing lap splicing, butt splicing or zero tail lap splices depending on the process needs. All of our single position unwinds are provided with automatic tension control and diameter calculation, and can also incorporate features such as shaft-less chucking of varying web widths, automatic guiding and built in pull rolls.




Multi-Position Unwinds

Multi-Position Unwinds

Many processes dictate that multiple unwind stands be incorporated into the web line. The necessity could be related to a multi web lamination process, or it could simply be required for staging a new jumbo roll in order to reduce downtime while a splice is being made. For these customers, New Era offers custom designed multi-position unwind stands. These units can be incorporated with accumulators so as not to stop the process while splices are being made and can also be provided with splice tables, allowing lap splicing, butt splicing or zero tail lap splices depending on the process needs. Additionally, we can incorporate a variety of semi-automatic and automatic splicing mechanisms on these units to give you on-the-fly splicing capability. All of our single position unwinds are provided with automatic tension control and diameter calculation, and can also incorporate features such as shaft-less chucking of varying web widths, automatic guiding and built in pull rolls.




Cantilevered Unwinds

For narrow width applications, or wide web, low bundle weight situations, New Era can custom design a cantilevered unwind stand. These unwinds can be single position, multi-position or fully automatic turrets with on-the-fly splicing. As with the wide web turrets described above, these unwinds are provided with automatic tension control and diameter calculation, and can also incorporate features such as automatic guiding, built in pull rolls, tool-less changeover of unwinding modes and even outboard supports for use with heavier jumbo rolls. Our cantilever designs are such that most mechanical actuation and drive transmission components are located on the back side of the machine frame, presenting a clean configuration to the operator.
