LOADING MATERIAL INTO THE SERVO FEED
Upon the satisfactory completion of all the tests, you should be ready to load a strip of
material into the servo feed.
Step number one is to select the manual mode of operation on the operators console.
Then choose “Operate Rolls”. This will allow you to open the feed rolls and anti-
backup rolls to accept the material. You could also open the rolls manually by lifting
the lever mounted on the side of the servo feed. Position the leading edge of the
material with the center of the material near the center of the entry rolls. Adjust the
edge guides on the cascade rolls to the proper width setting. Open the feed rolls and
or anti-backup rolls. Hand feed the material into the servo unit until it protrudes out of
the feed rolls and starts into the guide on the press. Close the anti-backup rolls (if
purchased) to capture the material, then close the feed rolls.
Check the roller force pressure to be sure that there is enough pressure to prevent
slippage but not too much to induce camber into the material. The pressure setting is
the amount of force necessary to move the material into the press at the speed and
feed programmed. You may find it necessary to readjust the force as you finalize the
setup procedure. The amount of force needed will vary depending on the width and
type of material being fed. Make a note of the final setting to aid in the setup of the
servo feed the next time the same material is run.
You are now ready to begin testing the complete system under power. To check the
progression, cycle the press in the single cycle mode with the servo feed in the
automatic mode. If the progression is correct, no further adjustments are necessary. If
the progression is either short or long, go to the troubleshooting chart and perform the
sequences described there for inaccurate feeding, once the feed progression has been
accuratelly set and the repeatability is satisfactory, you are ready for full automatic
mode.
