Dreistern's Start-Stop® technology provides precision roll formed parts at high production speeds.
In the Start-Stop mode, the advancing profile is stopped briefly during the cutoff and punching operations, after which the profile is accelerated to normal operating speed. All punching cutoff tools are stationary.
The tool designer does not have to make any compromises because of weight limitations for the tool, the company reports. The process provides high production output rates for short-length sections—60 sections per minute is normal. High-performance lines reach 120 sections per minute.
The roll former's drive system catapults the profile to a speed of 3,937 IPM.
