Abstract: front page image
(EN)A feedblock including a first packet creator (56) that forms a first packet including a first plurality of polymeric layers, the first plurality of layers including at least four first individual polymeric layers; and a second packet creator (58) that forms a second packet including a second plurality of polymeric layers, the second plurality of layers including at least four second individual polymeric layers, wherein the first and second packet creators are configured such that, for each packet creator, respective individual polymeric layers of the plurality of polymeric layers are formed at approximately the same time. The feedblock may include a packet combiner (54) that receives and combines the first and second primary packets to form a multilayer stream. In some examples, at least one of the first and second primary packets may be spread in the cross -web direction prior to being combined with one another.
(FR)L'invention porte sur un bloc d'alimentation, qui comprend un premier créateur de paquet (56) qui forme un premier paquet comprenant une première pluralité de couches polymères, la première pluralité de couches comprenant au moins quatre couches polymères individuelles; et un second créateur de paquet (58) qui forme un second paquet comprenant une seconde pluralité de couches polymères, la seconde pluralité de couches comprenant au moins quatre secondes couches polymères individuelles, les premier et second créateurs de paquet étant configurés de telle sorte que, pour chaque créateur de paquet, des couches polymères individuelles respectives de la pluralité de couches polymères sont formées approximativement en même temps. Le bloc d'alimentation peut comprendre un combineur de paquets (54) qui reçoit et combine les premier et second paquets primaires de façon à former un courant multicouche. Dans certains exemples, au moins l'un des premier et second paquets primaires peut être répandu transversalement au voile avant d'être combinés avec un autre paquet.
