ABSTRACT:
In the manufacture of a building element of the type in which an internal core member of a material of an open air-permeable structure is to be covered on both side faces with cover boards and on the edge faces with edge strips by gluing with a moisture-curing adhesive, contact pressure is established by applying suction directly through an opening in one of the edge strips to produce an underpressure in the core member. Thereby, and by applying the amount of moisture necessary to cure the adhesive to the cover boards prior to application of the adhesive, a considerable reduction of the processing time and, thereby, a simplification and cost reduction is obtained. Relative to usual mechanical pressure application technology, adhesive bonds having improved strength characteristics are obtained together with effective removal of poisonous fumes arising during the curing.
