Question about Singer 7442 Mechanical Sewing Machine

Open Question

I have a singer7442 I have barely used in the 3+ years I have owned it. It is sewing only one stitch at a time. The tension is fine, the bobbin is fine, the stitches look fine, but with each stitch the machine beeps 4 times and stops. I have to release the foot pedal and start over. Uggghh!

SOURCE: machine beeps and stops sewing, no error message displayed

sounds like not through the tension plate (on top) right... rethread and make sure you hold the thread taunt toward you as you putt through top tension... you should hear a slight click and some resistance...

Upper thread always cuts. Straight stitch doesn't work. The upper thread always cuts. The tension is No. 3. The stitches is adjusted to no, 2. The fabric is thin, soft and Lacey . Please advice.


Be sure to install a brand new needle of the type suitable for the fabric you are sewing.

Use a thread that is suitable for the fabric. If you are sewing fine, light-weight fabric, use a fine thread--avoid old or bargain bin thread. Use the same upper thread in the bobbin.

When threading, always raise the presser foot so the thread will seat properly in the thread tension and verify that the thread path is correct (consult the manual).

Standard tension is usually the midway point between high & low number. The stitch length could be set a little higher than a 2--maybe a 2.25 or 2.5 for light fabric.

Since you are sewing fine fabric, it sometimes helps to use a removable stabilizer to give the fabric some extra body while stitching--perhaps a wash-away stabilizer if the fabric is washable.

Test your machine on scraps of the fabric you will be sewing. Re-adjust the tension as needed. The correct tension is when both upper and bobbin threads meet in the middle of the fabric.

If the thread continues to break, then there could be a burr or nick somewhere that is catching the thread and causing it to break. Could also be a needle/hook timing issue.

How to adjust the bobbin tension.


According to the manual, you should not need to adjust the bobbin tension (and I located other sites which stated the bobbin tension cannot be adjusted on this machine). Apparently, all the tension adjustment is accomplished through the upper thread::
"EN Thread Tension Upper thread tension Basic thread tension setting: "4". (1) To increase the tension, turn the dial to the next number up. To reduce the tension, turn the dial to the next number down. A. Normal thread tension for straight stitch sewing. B. Thread tension too loose for straight stitch sewing. Turn dial to higher number. C. Thread tension too tight for straight stitch sewing. Turn dial to lower number. D. Normal thread tension for zig zag and decorative sewing. Correct thread tension is when a small amount of the upper thread appears on the bottom side of fabric. Lower thread tension The bobbin tension has been set correctly at the factory, so you do not need to adjust it. Please note: - Proper tension setting is important for strong seams. - There is no single tension setting appropriate for all stitch functions, thread or fabric. - A balanced tension (identical stitches both top and bottom) is usually only desirable for straight stitch construction sewing. - 90% of all sewing will be between "3" and "5". - For zig zag and decorative sewing stitch functions, thread tension should generally be less than for straight stitch sewing. - For all decorative sewing you will always obtain a nicer stitch and less fabric puckering when the upper thread appears on the bottom side of your fabric. 1 A B C 22 D"

Doing further research, I found this statement on a machine review site:
"After reading reviews online from where I've bought my drop-in bobbin machines, I think many of the negative reviews are due to the bobbin thread coming up without laying across the bobbin. It can cause the stitches to look very sloppy and no amount of tension adjusting can fix the stitches."

There are several machine review sites wherein 4423 owners stated their disappointment in the 4423's performance. Some said the machine failed almost immediately and others said the machines developed problems when sewing heavy fabric.

My Sew D'lite machine worked fine the last time I used it a year ago, but now it is not wanting to pick up the bottom thread regularly. It will sew regular stitches for a little while, and then stop...


It is time for cleaning. Open up machine and use a hair dryer to loosen dried grease. Use a qtip to remove dry grease. If done the right way it will take a while to do this. Moving parts that are moving has to be lubricated to lower friction and wear. Use only sewing machine oil. Lubricate the needle arm while it goes up and down and the race with one drop of oil. The race is a little area under the bobbin case that looks like a race track. Replace needle. This area should also be cleaned thoroughly. Set top tension to four. Pull on the thread to feel how much pull it requires to make the thread move. This is the same pull you will need for the bobbin. You may need to adjust the bobbin by turning the screw to get the right tension. It cannot be loose. The attempt is to get the exact same tension as the top tension just like a tug of war. After cleaning you may change your thread. It might be too old to use. Once all of these have been done you can thread the top and use one hand on the hand wheel to bring the bobbin thread up. It should come up easily. Try your machine. Leave the top tension set at four. If the stitches aren't so good make minute adjustments on the bobbin until you have a beautiful stitch. The top tension and bobbin tension must be the same pull. If you have done all this and it still doesn't give you a good stitch you will need to have it timed from your local pro.

Need new bobbins as the ones I have are not for


Hi Karen. First, you really do need a manual for your machine. I found one at http://www.sew4less.com/browse.php?CategoryID=5&filter_brand_id=83&filter_model_id=6040&go_filter.x=27&go_filter.y=9. Sewing Parts online also has your manual: http://www.sewingpartsonline.com/viking-sewing-machine-instruction-manuals.aspx
If the bobbins fit your machine and it makes a stitch, then the bobbins you have are fine--what you have is an adjustment problem, to get the stitch balanced. (I have a little tip/hint on adjusting the balance that might help you.) Here are a couple of things to remember when you're adjusting the tension:
1. Use different color threads in the bobbin and on top to make it easier to see
2. Thread your machine with the pressure foot UP. (Otherwise, the thread may not slip into the tension disks like it should.)
3. Adjust the tension with the pressure foot DOWN. (This engages the tension disks.)
4. Move the tension dial only a little bit at a time.
Hope this helps!

Brother vx790, my stitches are reversed ( top is on botom & bottom is on top )


It sounds like your tensions are out of adjustment. Your upper tension should be between 3-5 and make sure the tension in your bobbin case is not too tight as well. Pull the thread through the bobbin case and make sure it comes out with a small amount of resistance. If no resistance, tighten the tension just a bit, if too much resistance, loosen it just a small bit at a time.

Bobbin


To adjust any sewing machine for thin material do the following.

1.Use a fine needle,
2.Use a fine thread,(upper & Lower)
3.Reduce the the thread tension, Upper& Lower)
4.Reduce the presser foot tension,
5.Reduce the stitch Lenght.
6.Help the machine by pushing the material towards the needle while sewing. (don't pull it back.)

Bobbin tension


If the looping is happening on the underside, it is your top tension that is to blame, conversely looping on top is bobbin tension.........take a look HERE for detail on cleaning lint buildup.

Top tension should be set around the middle of the range, usually 4 - 6.

I would not advise playing with bobbin tensions, however, you can take the needle plate off to clean the hook race area (where bobbin case sits) ...this is good housekeeping, my wife does this every time she replaces the bobbin....just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint, if there appears to be fine dirty deposits, a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit will do the trick.

Thread tension?


I own this little gem of a machine. It definitely sews a perfect stitch. I'm assuming you own the green 3/4 size machine as denoted by your product number. The half size blue one pictured is incorrect.

Anyway, this machine sews a perfect stitch, due to the oscillating bobbin. Most sewing machines with rotary (drop in) bobbins don't have an easily accessible bobbin tension screw, which means your fabric is usually slightly puckered. Fiddling with only the upper tension helps very little. This frustrates me to no end for sewing long curtains, clothing side seams, etc. Wrong tension causes them to hang with puckers, making them look awful. With the Hello Kitty 3/4 size Janome, there is a screw on the bobbin case which allows you to adjust for every thread diameter perfectly. Always a perfect stitch, if you take the time to adjust this screw.

To adjust the bobbin for a perfect tension, load the bobbin into the bobbin case and thread it through the guide. Holding only the thread between two or three fingers, let the bobbin case dangle below. This will be slightly difficult, because the bobbin will want to fall out of the case. Don't worry, just don't move it around too much and it will stay in long enough for this test. If the metal bobbin case slowly drops lower, unwinding thread as it goes, the thread is too loose. Tighten the screw on the side of the bobbin case a little (about a quarter turn.)

If the bobbin case seems to be dangling firmly, give the thread a gentle tug, lifting up fairly quickly. If it doesn't release a couple of inches of thread, it's too tight, loosen the screw. You know the tension is perfect when a quick, light tug of the thread releases a couple of inches of thread.
