EMC 10 LOOPING & BIRD NESTING
Osman Bayrak
LOOPING & BIRD NESTING:
- Looping can be caused by thread tensions that are to loose and it can happen on the top or bottom of the design. Both the Bobbin and Tensioners could be the cause. Check to see if the problem is the tensioners by turning the tensioner knobs two (2) turns to the right to (Tighten) and see if it corrects the looping. Don't forget to check the bobbin for proper tension.
- Check the Black Tensioner Knobs for looseness on the Tensioner Post. The Tensioner Post is threaded and has a machined out slot in the middle of the shaft.
- If the knob is too loose, remove the knob insert the flat blade of a screw driver into the slot and spread it slightly, then install the knob again check for the tightness of the knob.
- The density of the design may have an affect on both of these problems. If the design density is to tight the needle may have a hard time penetrating the material and the thread may be pulled from the needle due to the tightness. Refer to your EDS Manual for information on Design Density. The density of small alphabet letters may be a cause also.
- If sewing small letters the 4.2 default density is to high for letters ranging from .50 inch or smaller. If using a Premier Keyboard for the controller, refer to the Premier Manual for proper density settings.
- The needle eye size can have an effect on both of these problems. If the density of a design is to high or the cloth is to elastic, change up to a larger eyed needle.
- For instance: If the needle currently being used is a 70/10 size needle, switch to a 75/11 or even a 80/12 size needle. This larger eyed needle will allow for smoother passage of the thread through the eye of the needle.
- Most thread being used is 40 gauge. If 30 gauge thread is being used a larger eyed needle is required, example 80/12 would be a size to start with. If Metallic thread is being used at least an 80/12 size needle should be used but if your garment permits, it is recommended to use a 90/14 size needle.
- Make sure that the Retaining Finger of the UTC Assembly is properly positioned in the Inner Basket Indentation. Refer to the Operation Manual for an illustrated view.
- There are some upgraded thread guides that can improve the smoothness of movement for thread when sewing. Call your distributor for information. Most "CE" version machines will already have the upgrades.
