ABSTRACT:
A straight line shear mechanism has rack driven shears which are operated by a pneumatic cylinder. The shear slides provide a barrier to infrared energy directed at the pneumatic cylinder. To cool the cylinder, a perforated cooling tube is connected to ambient air when the mechanism is operating and is connected to water when the mechanism is not operating.
