6. PNEUMATIC PILOT RELEASE
During operations such as forming or using pilots, the purpose of the Pneumatic Pilot Release is to release the strip
from being held by the feeder rolls. This allows the material to be adjusted slightly any time during the press cycle.
The pneumatic release mechanism is mounted centrally on the top of the feeder using (4) M8 screws and washers in
slotted holes. The slots are to allow proper alignment and adjustment with the release arm and roller.
Open the rolls allowing clearance between the upper roll and the material approximately 0.010”/0.25 mm.
(Use a shim on top of the material, if needed.)
Position the Pilot Release mechanism so that with the cylinder piston fully extended against the roller.
The SRF Pilot Release mechanism is pre-assembled, only needing outside air and electrical connections. For air
connections, refer to Figure 6.
The release is operated through the 3-way solenoid valve when the appropriate voltage signal is applied. This power
signal can come from a source such as a rotary cam switch.
The solenoid valve, located on the side of the feeder body, is provided with a cable attached to the solenoid valve for
connecting the power signal leads.
Air pressure of 80-100 PSI is required for proper operation of the release. A 1/4” tubing fitting is provided
for the air supply connection.
