This four station rotary hemming
unit is well suited for hemming a steel leading edge on the copper fin. This gives durable face core strength to your
copper cores by adding a steel leading edge. Rotary hemming units are used to roll form a hem or turn-up on the edge
of the fin. There are a series of rollers that form the hem in 4 steps. The first step is to form the strip at 45
degrees, then the next station forms the hem to 90 degrees, then the next station forms the hem under by 45 degrees,
lastly a set of rollers flattens the hem onto the parent material. A set of pinch rolls pull the material through
the machine and are operated by a dancer arm controlled motor. This motor runs at the same speed as the fin machine
providing a smooth supply of material up to the fin machine. Versatility is the biggest advantage of the Rotary style
hemming unit. This hemmer with the appropriate spacer plates can be setup to run a variety of fin sizes to match the
tooling in your fin machine.
• Use Steel Edge
Rotary hemming stations to strengthen your cores by adding a steel leading edge
• Flexibility is the main advantage
of the rotary hemming station by allowing one station to hem multiple fin patterns
• Solid spacers are used
to change from row to row keeping both the fin width and hem size exact.
• Quick Change guide pins are used
to guide the material through the hemming station
• Pinch rollers pull the material through keeping the fin
flat and feeding consistant into the machine
• Center trap plates to hold the material in place as it’s being
hemmed
• Small compact design to fit into your production space
