Tech Update
Clamshell Straightener Eases Maintenance for Wellman Friction Products
Coe Press Equipment, Sterling Heights, MI, recently installed a new clamshell-style Model CPPS-406-42 power straightener and a CPR-PO-15042 coil reel at Wellman Friction Products, Solon, OH. The manufacturer of friction components that go into brakes, transmissions, and clutches replaced exist- ing feed equipment on a 600-ton press line with the new straight- ener, to process material to 42 in. wide by 1⁄4 in. thick. The unit’s 30-hp AC variable-speed drive provides line speed to 60 ft./min., producing large clutch plates for use in earth-moving and farming equipment.
The straightener features an easy head-lift function that allows for maintenance and cleaning. Wellman expects that the unit will reduce downtime compared to the older unit, which required disassembly of the straightener head to clean the rolls. With the new straightener, the top rollers separate from the bot- tom rollers to provide access to the straightening rolls for inspec- tion and cleaning. Pushbutton controls are used to activate hydraulic cylinders that raise the head containing the top rolls.
The CPPS-406 model features 4.0-in.-dia. straightening rolls and 6.3-in.-dia. pinch rolls. Other features include a nine-roll straightener, an alligator-style peeler for effective dekinking and threading operations, and independently adjusted powered coil
guides for effec-
tive coil loading
and guiding.
Wellman also
opted to include Coe’s

self-centering hand-crank entrance edge
guides and a Trabon automatic-lubrication system. Coe Press Equipment: 586/979-4400; www.cpec.com
