EMC 10 THE CAP FRAME IS POPPING OFF

Osman Bayrak

THE CAP FRAME IS POPPING OFF OF THE CAP FRAME DRIVER OR THE DESIGN IS BEING FLATTENED OUT NEAR AN EDGE OF THE CAP FRAME SEWING FIELD:

  1. Make sure that the Cap Frame Driver shaft is pushed in so that the metal collar is flush against the Rear Cap Frame Bracket and the Dove Tail Mount is properly installed in the Dove Tail Bracket. Make sure that the thumb screw is tightened and the shaft will not move back or forth. Refer to the Operation Manual for instructions.
  2. Check the cables attached to the Cap Frame Driver for looseness. If the Drive Bracket can be pulled out of it's grooves then the cables are loose.
  3. If the cables are loose they can be adjusted by loosening the two socket head cap screw that are located at each end of the Driver Bracket. Loosen one side only and push the Cable Bracket out till the cables are tight.
  4. If the cables are tightened too much they may bow the Driver Bracket. If the cables have stretched to the point that after adjusting both Cable Bracket the looseness can not be taken out then replace the cables.
  5. The needle plate can also cause the Cap Frame to pop off. Check the needle plate for wear marks and nicks along the front and side edges that may have been caused by the Cap Frame.
  6. If there is evidence, then power off the machine and leave only the Cap Frame Driver installed in the Pantograph. Pull the Pantograph forward so that the front arc of the Cap Frame Driver is over the side edges of the Needle Plate.
  7. Center the driver and turn it left and right to see if the front arc of the driver touches either side of the Needle Plate.
  8. If it does the Driver may be warped or the cables may be too loose. The Driver must clear the Needle Plate by at least 1/16 of an inch to be correct. Check the Rear Cap Frame Bracket for looseness or any thing in that area that may cause the Cap Frame to pop out.
  9. Check the Cap Frame Driver Roll Clips for wear, damage or looseness, replace as needed.
  10. Check the Cap Frame for damaged parts and the proper arc of the Weldment Frame. The Weldment Frame has a piece of metal that is used as support at the front and underneath the frame. This part can cause the Cap Frame to pop off if it hits the Needle Plate.
  11. Check the X-Axis carriage for play in the X-Carriage Rollers or loose Hoop Holder pins. Refer to the Technical Manual how to adjust the X-Carriage Rollers.
  12. Make Sure the Cap Frame Hoop Mounting Bar is riding in the arced groove. If not place the bar back in the groove. The bar can cause a tight bind if the bar is outside of the groove.
  13. The Cap Frame can be bent inwards, so that the arc of the cap frame is smaller. This will cause the edges to hit or rub on the needle plate. Set the Cap Frame on a table. Hold down on the right side of the frame, and pull up slightly to slightly widen the arc so it does miss the needle plate by very little. This is an un-scientific way of fixing the problem, but it will work if the cap frame is bent inwards.
