Problem with spool Thread, please suggest a solution!
I have properly placed both bobin and spool threads in their respective places with the help of manual .The first use was successful.But from the second time , Janome minisew's spool thread is making loops with it self. It's not recognising the bobin thread at all. And the machine is getting stuck. If not, all the thread loops are getting accumalated on the reverse side of cloth. It's driving me crazy.I need some sincere advice n help.

Re: Problem with spool Thread, please suggest a solution!
This is a tension problem.
In addition to the top thread having a tension adjustment there is the facility to adjust the tension of the bottom(bobbin) thread.
Both these tensions need to be correct to get a balanced stitch and to stop the loose threads underneath the cloth.
It is almost impossible to explain how to adjust the bottom tension you need to be shown.
Somewhere in your manual it should explain how to do this.

Found this on the internet.
There could be several things that could cause the machine not to pick up the bobbin thread.
The upper thread could be tangled.
Remove the thread completely from the machine.
The correct size spool cap should be used for the size of the thread spool.
Re-thread the machine according to the directions in the manual.
Flip the presser switch up to raise the presser foot. Turn the hand wheel counterclockwise until the needle is in its highest position.
2Hold the hand wheel in place with your left hand while turning the hand wheel knob counterclockwise with your right hand to loosen the hand wheel knob.
3Place the desired spool of thread on the spool pin so that the pin fits all the way through the hole in the center of the spool. Put the spool holder onto the end of the spool pin that is sticking through the spool of thread and press firmly to ensure that the spool holder keeps the spool in place.
4Grasp the end of the thread and hold it taut between the thumb and index fingers of both hands. Snap the taut section of thread into the thread guide post located to the left of the spool pin.
5Pull the end of the thread gently. Wrap the thread around the bobbin winder tension disk near the left front on top of the machine, starting at the side of the tension disk facing you and wrapping around in a clockwise direction.
6Poke the end of the thread through the small hole in the bobbin from the inside out so that the loose end of the thread sticks through the top of the bobbin. Put the bobbin on the spindle, or bobbin winder, and gently slide the bobbin winder to the right.
7Hold the loose end of the thread in place while pressing down on the foot pedal to start the machine. Hold the foot pedal down until the bobbin is as full as desired. The machine will automatically stop once the bobbin has reached capacity.
8Cut the loose end of the thread using scissors. Slide the bobbin winder to the left and remove the bobbin. Hold the hand wheel in your left hand and tighten the hand wheel knob with your right hand by turning it clockwise
Upper Thread Tension knob on machine is too tight.or needs cleaning to remove lint. Once the needle has been threaded, you should be able to pull thread through the needle with only a modest effort and no breaking.
There is also an adjustment for the lower bobbin (spool) on the spool carrier. for most machines.
The thread coming out from the spool passes under a flat spring to give it tension for an even stitch- to tight it breaks the thread, too loose it leaves you with excess thread per stitch.
If you can remove carrier with bobin, let out about 1 or 2 handspans of thread, and hold the carrier up by the thread. If it falls, it is too loose. If it does not move, not even with a gentle shake- it is too tight. Correct tension will hold the carrier and spool by their weight, and a light shake will have the assembly slow fall as it unstrings the bobbin. The flat spring is held in place by a small screw, just loosen the screw slighlty to allow you to slide the spring one way or the other and retitghten.
I found a website for you that might help. They have a lot of kenmore manuals including one similiar to your model#148.12051. The manual opened as model 1205 so maybe searching for your model as the 1201 might help too. hope this helps! =)
I assume you mean when you wind a bobbin full of thread??
You take the end of thread from your spool through the tension device or an eyelet on top of the machine, then back to the bobbin on the bobbin winder and thread the loose end through a top hole on the bobbin. Click the bobbin in against the stop and press on the pressure foot to start to wind. Hold the top thread for a bit as the bobbin starts to fill and then once it has been covered by a row or two of thread, stop and cut of the loose end from top of the bobbin. Now continue to wind the bobbin until it cuts out as it fills against the stopper. Nudge the thread with a finger tip as it spools onto the bobbin to help get the bobbin filled top and bottom and not just in the middle. (bit like when you coil the garden hose onto the reel, it always wants to go in the middile only and then jams up LOL).
Also a really good idea to place your scissors handle into the top of the thread spool to slow/control it as the thread reels off it. This helps give an even tension on the thread going onto the bobbin which really helps with stitch quality later.
From your description it appears that you have tried tension settings on the upper tension control adjustment knob without success.
Check that the bobin tension is adjusted correctly by taking out the bobin complete with the spool.
Pull the cotton thread and it should be a smooth light pressure if the tension is correct. If it is tight to pull or pulls freely then adjust the tension screw which is found on the outside of the bobbin. The screw is very small and requires a minature size screwdriver. The adjustment will only be a slight turn of the screw one way or the other to obtain the correct tension(depending if it was loose or tight).
Once this is set reinstall the bobin and tread up the machine, hopefully with the upper tension set at approx."2" the machine will sew correctly.
