Conair coil strapping system protects extruded tube and simplifies handling

A new coil strapping system introduced by Conair for its ATC Series tube coilers automatically and securely straps finished coils of small-diameter extruded tubing.

Handling coils up to 24in (61cm) in diameter, the system prevents tube damage or unraveling and makes the coils far easier to grasp, handle and move. It uses roll-fed PP and PET strapping and is FDA-compliant for medical-tube applications.

The optional system comes in two pieces. The first is a separate steel stand that holds two large strapping rolls, which is positioned approximately three feet from the end of the ATC Coiler. The second is the automatic strapping head unit, which is mounted on a sturdy steel base that attaches directly to the base of the ATC Series coiler on the coil-outlet side. This consists of a strap guide roller, an alignment arm, and a combination strap cutter/welder head that affixes, cuts, and welds the strap material.

The strapping system control integrates directly with the ATC coiler control via a secure Ethernet communications connection.

In operation, the strapping system is actuated by a signal from the ATC coiler that a full coil of extruded tubing has moved into position. The alignment arm of the strapping system extends to check the coil position, followed by the cutter/welder head. The head attaches one end of the strap to the tube coil, which is then rotated. The head then cuts the strap material and ultrasonically welds the finished coil strap before retracting. The system can apply one, two, or four straps to a tube coil.

The strapping system is fed by two rolls of PE or PET strapping material, each containing enough to wrap up to 4,400 coils with one strap or 1,100 coils with four straps.

Should strapping material run out, the ATC Coiler’s automatic in-line accumulator ensures that tubing production continues with no shutdown required.    

The strapping system is available as a factory option for new ATC coilers or as a retrofit for existing units. The coiler fully automates transfer of tube winding when a coil is full, eliminating the need for operator involvement or process disruption.

Additional ATC Coiler features, including automatic unloading, conveying, and wrapping of strapped coils, are planned by Conair for future release.
