Pneumatic Brakes Mistral Brakes Modular design permits variable tensioning capacities! Wichita Clutch’s Mistral pneumatic tension brakes are ideally suited to the needs of the corrugating market for which it was originally designed. It is also a versatile product which is finding favor in additional tensioning applications. Wichita Clutch designers and engineers consulted extensively with mill roll stand manufacturers and users to offer a tension brake ideally suited to the needs of this particular market. The result is a compact, high performance, versatile brake capable of handling the tensioning needs of the latest machine designs, as well as existing equipment. The Mistral paves the way for increasing line speeds by 5.4 feet/sec. from 810 feet/min. (or slower) to 1,140 feet/min. Varying number of actuators provide optimum tension control Each brake may be specified with a varying number of pneumatic actuators, allowing precise selection of brake torque capacity for optimum tension control. Compact Design Mistral brakes are compact at only 11.6" or 16.1" in diameter. Their size facilitates the pickup of small, part reels used in short batch runs. For automatic reel loading machines, Mistral offers optional infrared and speed sensor installation within the brake. And their modern, industrial styling enhances the appearance of any machine on which they are used. Performance Curve 547,000 feet Mistral brake at 1,140 feet/min Easy Access with Removable Cover Panel By removing just three cap screws, the Mistral’s front cover can be detached for easy and fast access to internal parts. Cover removal automatically disconnects both air and electricity. Current brake at 810 feet/min

Pneumatic Brakes Mistral Brakes Mounting Ease Three bolts mount the brake to the arm of the mill roll stand or machine frame and an optional pilot location makes fitting to both new and existing machines a simple operation. Mistral’s integral guarding eliminates the cost and effort of installing external guards. Operator safety is further enhanced by automatic air and electric disconnects when the front cover is removed. Integral Cooling Wear Indicator A brake wear indicator, which is conveniently located for easy visual inspection, means no down time to check remaining friction material life....
