of the middle layer consists of synthetic fibres and 90 of absorbent fibres the proportions between the synthetic fibres and the absorbent fibres such as cellulose fibres 7 8 this means that 47 of the top layer consists of synthetic fibres and 53 of absorbent fibres the process processes in a way that the first forming bead 41 will be supplied with the fibres for the bottom layer the other forming head 42 with the fibres for the middle layer and the third forming head 43 with the fibres for the top layer thus the three layers will be formed in each layer 39 s separate forming head 41 42 43 and successively will be laid on top of one another subsequently the process continues in the same way as described for the first construction form the in fig3 shown fourth construction form for a plant according to the invention separates itself from the above mentioned and in fig3 shown third construction form by now similar to the other construction form and as shown in fig2 a special continuous thermal bonding oven 36 is inserted between the conveyor and the hydro entangling section 3 similar parts are therefore also in this case indicated with the same reference numbers with this setting of the plant according to the fourth construction form the same advantages will be achieved.
