The felt machine with 4 rolls

Use JPP- felting machine

Woolfelting a creative process, but hard work too!

Wool felting is an ever popular creative process, that has been around for centuries, a variety of products such as; hats, bags, cushions, blankets and tapestries, can be made. Felting is physically very demanding, especially so for people, to whom it is more than just a hobby. Arm- shoulder- and backaches are frequent complaints and when spared such problems, one might feel restricted by the limited number of hours to be spent felting. The JPP-felting machine offers relief from the physically demanding, without hampering the creative side of the process.

The JPP-Felting machine
What distinguishes the JPP-felting machine is the fact that it has four eccentrically revolving rolls, i.e. two top and two bottom rolls. The PE-roll, with wrapped around it the wool inside the bubble wrap, revolves between these four rolls, resulting in maximum friction and a remarkably stable chore. Working length of the standard machine is 1.60 mtrs, which can be extended to 2.50 mtrs. Further extending the piece of work to up

to 5.00 mtrs in length is possible by feeding it into the machine folded over. When making smaller pieces, several can be made in the same run. On demand JPP will also make machines to measure. Maintenance of JPP-Felting machines is easy as they are made entirely of stainless steel.

General users information for the JPP- felting machine The JPP- felting machine may only be used for wool felting and was made with the experienced felter in mind.

To use the JPP- felting machine you will need the following: Bubble plastic / wool / water /soap without glycerine or Marseille soap / a bucket / elastic bands and the PE-roll, to be taken out of the machine and used to wrap the bubble plastic and wool around.

Laying out of the wool Roll out the bubble plastic on a table and spread the wool on top, leaving 10 cm uncovered at the top and the bottom and 5 cm on the left and right side of the plastic. This is necessary to keep the wool covered completely by the bubble plastic during the felting process. Wet the wool, after laying it out, using warm water and any non-glycerine soap or Marseille soap. Beware that using soap containing glycerine can adversely affect the working of the JPP felting machine.

Using the PE-roll 
Wrap the bubble plastic with the wool around the PE-roll firmly and evenly. To ensure the first layer is tight enough it may be tacked to the PE-roll. After the roll is fully wrapped, use the elastic bands to secure and prevent it from coming unwrapped during the process.

Which PE-roll do we use The JPP- felting machine comes equipped with one 10 cm diameter PE-roll and a second with a 15 cm diameter, both to be found in the machine. The minimum diameter of PE-roll plus bubble wrap and wool should be 17 cm for the machine to operate properly. Consequently, when using a small amount of wrap and wool, the 15 cm PE-roll should be used. The maximum diameter of PE-roll plus wrap and wool should be 35 cm, so when using a large amount of wrap plus wool the 10 cm PE-roll should be used.

Using the length of the PE roll The thickness of bubble wrap plus wool should be evenly divided over the PE-roll, by either covering most of the roll with a large piece, or by spreading a number of smaller ones over the roll. For example, a piece only covering half a meter of the roll may be balanced by placing two pieces of a similar size, to the left and right of the first piece, on the roll.

Using the JPP- felting machine
Before starting the actual process set the time, speed and also the top roll pressure. Working with different settings will give you the experience to reach the desired result.

The felting process evolves over several rounds. As the process works hardest on the outside of the roll, it is necessary every couple of minutes to stop the machine and take out the roll in order to turn the wool over, add some extra wool where necessary and straighten the piece out. This procedure to be repeated several times to achieve a well-balanced piece of work.

Special care should be taken with the very first round. The wool will shrink fastest and will as a result start shifting in the wrap. So the first round should not be too long. Also on the first round quite a lot of water will be pressed out of the wool (the water is caught in a bucket under the machine). Therefore it is important to have the rolls only turning in one direction for the first two minutes (setting L) before being able to use the alternating directions setting. (L/R)
