This new machine is designed to allow fiber to be fed vertically and pre-opened with a feedroll, main cylinder and brush roll. Rando rolls are wired vs. the competitors pinned rolls. Wired rolls are more cost effective to manufacture and require less servicing by the customer, keeping your line up and running!
Robustly built, the Rando Vertical Pre-Opener is manufactured in standard widths from 36” to 100”. It is highly recommended for BICO, Natural, Metal and Ceramic fibers. Our engineers are dedicated to finding new ways to open high-cost fiber such as BICO. Ensuring all bundles, tufts and filaments are 99% opened saves on material costs and creates better bonding characteristics.
The vertical design creates a smaller footprint than earlier designed pre-openers that fed horizontally, thus running cleaner with gravity and constant vacuum pressure.
In trials The Rando Vertical Pre-Opener was used successfully with natural fibers for reducing breakage. Rando had great success in running fiberglass in stick form; pre-opening the sticks so downstream equipment can process the fiber with less fiber loss and better opening.
This new machine from Rando can be mounted to other feeding machines or can be pneumatically fed. The fibers are pre-opened and are removed with an air handling system to the next machine in use. It can also be used as a standalone machine.
