Plant and method for connecting a web of fibrous material to a nonwoven or consolidating it therewith
A plant and a method for connecting a web of fibrous material to a nonwoven or consolidating it therewith includes a first circulating belt on which the web of fibrous material is laid, a device for introducing a nonwoven into the plant, and a further successive circulating belt on which the nonwoven is to be connected to or consolidated with the web of fibrous material. The web of fibrous material from the first circulating belt is first laid on the nonwoven and subsequently the fibrous material is transferred onto the successive belt together with the nonwoven for connection or consolidation by use of water jets.
1. An installation for bonding or entanglement of a web of fibres, comprising:
a first circulating belt having a roll and being arranged for depositing a web of fibre material thereon, the web of fibre material having an upper side remote from the first circulating belt;
a further circulating belt arranged downstream of the first circulating belt;
an apparatus for introducing a nonwoven into the installation arranged in a region of the roll of the first circulating belt; wherein the roll of the first circulating belt is arranged so that the web of fibre material and the nonwoven are guided around the roll at a deflection angle so that a compaction of the web of fibre material takes place between the roll and the nonwoven, and the nonwoven together with the web of fibre material are transferred to the further circulating belt; and
at least one water bar for producing water jets arranged for bonding or entanglement of the web of fibre material and the nonwoven on the further circulating belt.
2. The installation according to claim 1 , wherein the apparatus for introducing the nonwoven into the installation includes a further roll.
3. The installation according to claim 1 , further including at least one water bar arranged inside the first circulating belt to detach the web of fibre material from the first circulating belt.
4. The installation according to claim 1 , wherein a spacing between the first circulating belt and the further circulating belt is greater than a thickness of the nonwoven with the fibre material deposited thereon.
5. A method for bonding or entanglement of a web of fibre material with a nonwoven, comprising;
depositing a web of fibre material on a first circulating belt of an installation for bonding or entanglement of the web of fibre material with a nonwoven, the web of material having an upper side remote from the first circulating belt;
introducing into the installation an incoming nonwoven in a region of a roll of the first circulating belt so that the upper side of the web of fibre material is deposited on the incoming nonwoven, wherein the introducing includes guiding the nonwoven and the web of fibre material around the roil at a deflection angle so that there is a compacting of the web of fibre material between the roll of the first circulating belt and the incoming nonwoven;
subsequently transferring the nonwoven together with the web of fibre material to a further circulating belt arranged downstream of the first circulating belt; and
bonding or entangling the web of fibre material and the nonwoven on the further circulating belt by water jets.
6. The method according to claim 5 , wherein the introducing step includes introducing the incoming nonwoven into the installation via a second roll.
