Claim 0:
1. An apparatus for bonding a first layer comprising short fibers with a second layer comprising long fibers to form a non-woven web, the apparatus comprising:
a first circulating belt on which the second layer comprising the long fibers is depositable and displacable in a direction of production;
a second circulating belt via which the first layer comprising the short fibers is transferable at a transition point to the second layer comprising the long fibers;
a pre-bonding unit which is arranged directly behind the transition point in the direction of production, the pre-bonding unit comprising a first compactor and a second compactor which are arranged spaced apart from one another in the direction of production, the first compactor and the second compactor each being configured to act in one region on the first circulating belt or in one region of the second circulating belt; and
a bonding device which is arranged between the first compactor and the second compactor in the direction of production, the bonding device being configured to bond together the first layer with the second layer by twirling the long fibers and the short fibers,
wherein,
the first compactor, the second compactor and the bonding device are integrated into the apparatus so as to always be in an operating state together when the first layer comprising the short fibers is transferred using the second circulating belt.
