The stitches my sewing machine is producing are too large on the bottom making me think the bottom tension is out ... because I have lost the manual and it is an old machine I'm not sure which way to turn the screw down the bottom to tighten - does anyone know which way to turn the screw?

Re: Globe Cub 7 sewing machine
Hi Quinny1420...If you are certain that it is a tension issue, first ensure that your upper threading is correctly inserted/passing through the upper tension discs, and the general upper tension starting point is between 3.5 and 5.5. Increase the upper tension to pull up loose stitching on the bottom. Last resort is to alter your bobbin tension. Clockwise to increase, and counter-clockwise to decrease. Turns should only be made in 1/5 increments between test sews.....Please update your post of your progress...good luck my friend

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.
I think you are saying that there is a loop showing on the bottom of the lower thread stitch. If the lower stitch looks correct and not bunching, you will need to change the tension on the upper stitch. Make sure that your threads are firmly inserted within the discs also before adjusting the tension. It doesn't take much to change the tension so take it slowly.
Hi Leann: Think about how a sewing machine works. Now think about what kind of difference an 1/8th of an inch distance would make. Yes. You will need to adjust your top tension when you do free motion work. Keep in mind that plate is not just stopping your feed dogs from working... it's holding your materials that far away from the bed of the machine... so when the thread makes a loop and tightens for the stitch it has the extra 1/8th of an inch to make up for... if the tension isn't right... you got loops. There are no "specific" settings for tensions... you learn by doing you stitch a few stitches on like materials and tighten until you see a good stitch.
Make sure you have the right size needle...not to small. Then do a simple seam through three layers (doesn't need to be a seam just sewing through 3 layers of scrap) using a wide zig zag stitch. Examine the stitch looking at both sides. Do they look even, identical?
Think in opposites, ie the bottom thread tension affects the stitch on the top side and the thread tension on top affects the stitch on the bottom side. If one side is loopy then the opposite side tension is too loose (or, sometimes that side's tension is too tight). Adjust until both sides are identical looking. Then try stitching in the ditch like you wanted to.
usually a tension of 3 or 4 is good
only if the presser foot not is not made for zig zag--all the presser foot's that I've seen on new machines do straight stitch & zig zag,, if the opening in the foot is large then manually try a zig zag stitch to see
My guess is that you have lost all of your upper tension and you may have your needle in backward. Unthread the machine.Raise the presser foot.Turn the handwheel until the take-up lever is at it's highest position.Set the upper tension dial/knob to 5.Remove the needle and replace it making sure that the flat side of the needle shank is to the back.Thread the machine. With the presser foot up, the upper thread should pull through easily and then grab when the presser foot is lowered. Test sew. The upper tension pulls the stitches up and the lower tension pulls the stitches down. When they pull properly, the stitch is even.
I have had this problem when the bobbin was wound wrong and also when the machine was improperly threaded. Check your manual to make sure you hit all the threading points, but I think the most common one i've missed that caused this was the metal loop you thread immediately before threading the needle.
Have a look at this website.
If they do not have the manual you want email them and they will help.
The looping problem is the bottom tension is to slack, on the same website look at the repair section and it explains how to adjust the bobbin tension. www.sewusa.com
