Why does the motor on film tension never stop turning on my Wulftec packaging equipment?
- F
  Frank LeeAug 13, 2025
  If the motor on the film tension of your Wulftec packaging equipment never stops turning, it could be due to several reasons. The steel cam may not be touching the analog sensor when the dancer bar is at rest. Try turning the steel cam closer to the analog sensor or moving the analog sensor toward the cam; these are located under the red cover on the film carriage. Alternatively, the minimum speed trim pot on the pre-stretch drive might not be set to minimum, so turn it counter-clockwise. Also, check the tension adjustment spring on the side of the carriage; if it's set too light, increase the pressure by turning the knob clockwise. Finally, ensure that the clamp is closed.

What to do if the heat wire does not cut the film on my Wulftec packaging equipment?
- M
  Melinda JohnsonAug 16, 2025
  If the heat wire on your Wulftec packaging equipment isn't cutting the film, several factors could be at play. First, ensure the push arm is engaging completely; check the reed switch to confirm the PLC receives the signal when the arm is out. Next, inspect the fuse for any shorts; if none are found, replace the fuse with one of the appropriate rating. The cut wire itself may be broken, so replace it with a .032 gage nychrome wire. Additionally, the flow controls on the cylinders might need adjustment; look for kinks in the hose, and if none are present, adjust the flow control on the cylinder. Also, verify that the air pressure to the system is adequate; the pressure gauge should read no less than 80 PSI. Lastly, the cylinder itself may be defective, in which case it should be replaced.

  If the power light is not on for your Wulftec packaging equipment, there are several potential causes. Start by checking if the main fuse is turned off and turn it on. The light bulb itself may be burned out, so try replacing it. Ensure that the main switch is in the on position. Check the main fuses and related glass fuse for shorts; if none are found, replace the fuse with the correct rating.

  If the heat wire on your Wulftec packaging equipment does not return to its starting position, it could be due to a few reasons. The flow controls on the cylinders may require adjustment; check for any kinks in the hose and adjust the valve flow control accordingly. Make sure that the air pressure is adequate; the pressure gauge should read at least 80 PSI. If these steps don't resolve the issue, the cylinder may be defective and require replacement.

  If the motor on the film tension of your Wulftec packaging equipment never turns, it could be due to a few reasons. Start by checking the motor fuse for any shorts; if none are found, replace the fuse with one of the appropriate rating. Ensure that the motor fuse is turned on. Also, check the fuse on the analog board for shorts; if none are found, replace the fuse with the correct rating. If these steps don't resolve the issue, the analog sensor may be defective. In this case, call technical service at Wulftec.

How to fix clamp that does not open after 1-1/2 turns on Wulftec packaging equipment?
- S
  stewartbrianAug 31, 2025
  If the clamp on your Wulftec packaging equipment does not open after 1-1/2 turns, it could be that the air cylinder is not retracting. Check the hose for any kinks and, if none are found, adjust the valve flow controls. Another possibility is that the carriage bottom limit stop may be too low, causing the film to wrap too low onto the clamp and preventing it from opening. In this case, move the stop block higher so that the film wraps approximately 5 inches over the clamp jaws.
