Abstract:
1. A method for continuously producing a laminate with at least one powder layer, comprising directing a first layer along a longitudinal direction to a second layer; applying powder to the first layer continuously along the longitudinal direction to form several longitudinally extending continuous powder strips adjacent to one another; before applying binder to the first layer and before arranging the second layer on the powder layer and the first layer, removing portions of each of the continuously applied powder strips from the first layer, thereby producing powder layers that are separated from one another and which are arranged one after another in the longitudinal direction; applying binder to the first layer at least in strips between the separated powder layers in areas that have been cleared of powder; and directing the second layer onto the powder layer and the first layer and forming a transversely extending seal between the first and second layers along the strips of binder.
