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)
