Abstract (en)
[origin: US2022307177A1] An apparatus for bonding a first layer having short fibers with a second layer having long fibers into a non-woven web. The apparatus includes a first circulating belt on which the second layer is depositable and displacable, a second circulating belt via which the first layer is transferable at a transition point to the second layer, a pre-bonding unit arranged directly behind the transition point, and a bonding device. The pre-bonding unit has compactors which are spaced apart from one another. The compactors act in one region on the first or second circulating belt. The bonding device is arranged between the compactors and bonds together the first and second layers. The compactors and the bonding device are integrated into the apparatus to together be in an operating state when the first layer is transferred using the second circulating belt.
