REBUILT LOCKFORMER DRIVE TURN HEMMING

Manufacturer: LOCKFORMER
Model: DRIVE TURNER HEMMER
Condition: Rebuilt

This is a 100% MADE IN USA Lockformer Hemmer “Turning the drive” by means of a Rollformer instead of a Cleatbender speeds up production on S & Drive Fittings. Both use ½” of material to Rollform the Drive Turn hem 7/16″ x 180°
This rebuilt Lockformer Drive Turn Hemming Machine features the Lockformer Skip Dent Indexing Roll which is the heart of the system. The indexer is the first roll and has four pins and two milled ridges. The control lever determines whether the blank is hemmed after the first or second notch. With the lever in position 1, as the blank engages the indexing roll, a pin drops into the first notch. A ridge adjacent to the pin pre-bends the material at its corner just enough to force the material into the hem forming rolls where the 180 degree hem is formed. The next pin, on the rotating index roll, drops into the second notch and since there is no ridge present, the corner of the blank is not turned down and misses the hemming rolls and this section remains unformed.

The 10 Station Rollforms the cleat edge by means of a laser that acts as a Notch depth sensor that triggers the air cylinder to raise or lower. Capacity of 20-26 ga galvanized metal. Outboard side of auxiliary shafts for additional tooling if desired.
