Uncoiler – DSUNC Small (DSUNC-S)

The DSUNC-30 series is a special double spindle Uncoiler mainly used for handling one narrow strip and one wide strip for Brass Edge laminated Fins. These are simple, robust designs that suit the individual needs of the machinery they are sold with. There are two spindles, over and under, to handle the coils while maintaining a small floor footprint. The DSUNC-30 uncoilers are loop controlled, with a DC motor using a dancer arm-controlled potentiometer to regulate the uncoiling speed. These are equipped with tight web sensing, where the uncoiler will send an e-stop signal to the machine to stop the process once a tight web is sensed.

Options Available:

  • Expandable Aluminum Arbor: Available in two sizes, 2.95 in [75mm] and 3.94 in [100mm], and with extensions cover a range up to 11.81 in [300mm] in core ID diameter.
  • Linkage Type Arbor: Used for the larger ID coils. This uses a linkage assembly to expand the outer shoes to the ID of the Coil. This is a much heavier duty arbor assembly and is used for coil ID’s of 11.81 in [300mm] to 15.75 in [400mm].
  • Cone Style: These are simple cones that fit into the ends of the Material Core. They are very flexible and are usually used on core ID’s of 5.91 in [150mm] and less. They consist of two cones that wedge themselves into the core ID.
  • Hub Type: These arbors are ones made for a specific core ID. Therefore, if the core is a 7.87 in [200mm] ID, the Hub would be just under 7.87 in [200mm] and slip into the core. These are useful when the ID is always the same size, can be made special to any diameter, often simplify the setup of the uncoiler.
