fills. If you have to do this, stop the machine before it begins to stitch on the other heads and manually pull back the thread on those heads. It takes less time than re-threading. Thread Problems Wrong Thread Path. This is most common to new operators. Follow the manufacturer's recommended thread path for your particular machine. Wrong Thread Thickness For Needle Or Design Density Knots Or Slugs. Occasionally a cone of thread can be found to have knots or slugs. Slugs are lumps or fat sections in the thread. If a cone has several knots or slugs, most thread manufacturers will issue a credit or replace that cone. Bruised Cone Of Thread. Some types of cones can be bruised if dropped on the floor. This bruise causes the lower windings to catch as the thread is spooling off, causing a thread break. Watch the cone as it is sewing. If the thread becomes taut at the same place on the cone, look for a bruised edge and then proceed. Often times the cone is not dropped but rather pulled off the shelf as a result of not tying off the loose ends of other cones. You can tie off partially used cones by using a sock or net. (Definitely do not use tape. Read on.) Using Tape To Tie Off Loose Ends Of Thread Cones. Tape often leaves a residue on other windings of a cone. As this residue passes through the eye of the needle, it causes friction and thread breaks. Cone Of Thread Is Loosely Spun. Sometimes the threads on a loosely spun cone that has been handled too much or too hard can drop to the skirt of the cone. On cones without flanged bottoms, use a felt washer underneath while running to keep the thread from catching under the cone and causing thread breaks. www.hsi.us care@hsi.us 218
