Conair coiler targets high-speed medical tube winding

Now Conair is launching a dual-spindle automatic cut-and-transfer coiler that targets high-speed winding of small, flexible extrusions. Nominal line speeds range as high as 800 ft/min (243 m/min), depending on size of the extrusion being coiled.

According to Conair, even at these speeds, little or no friction or winding tension is generated, preventing deformities in delicate products making the unit suitable for extrusions such as medical tubing, small tube, and small flexible profiles. Fully automated transfer of winding to a new reel means there is no operator involvement or process disruption, which effectively increases line speed and performance during changeover.

"Speed is what sets the Conair ATC coiler apart," says Chris Weinrich, general manager, Downstream Extrusion, Conair. "No other coiler in its price range offers these speeds, along with automatic cut-and-transfer. In addition, it is part of a complete line of proven downstream extrusion equipment. From the die to the shipping container, Conair offers multiple choices for sizing, shaping, cooling, pulling, cutting and handling of extruded products from microbore medical tubing to large pipe and profiles. No other supplier can match our experience or breadth of product line."

Conair ATC coilers target tensionless winding of small-diameter flexible tubing. Typical tube diameters are 0.085 to 0.5 inch (2.16 to 12.7 mm), while tubes as small as 0.020 inch (0.5 mm) in diameter can be accommodated with a special minimal tension trim control.  Units are available in three different sizes with maximum coil diameters of 24, 36 and 48 inches (61, 91 and 122 cm).

Automatic turret changeover is completed when a set length of product has been coiled. The system comes complete with collapsible core assemblies or spools and can optionally accept customer-supplied spools. All winder components that come into contact with the extruded product are made from stainless steel or are hard-coat anodized.
