- This study presents an opportunity to utilize peeler cores derived from poplar wood for the production of hollow beams. In this way, final products to meet the needs of consumers can be obtained. The proposed novel methods for sawing and gluing the produced materials allow rational application of the waste raw material in the plywood manufacturing. Another advantage in this case is that products with a square cross-section with dimensions close to or corresponding to the standard ones are obtained from small-diameter round wood. The raw material used to receive the proposed hollow beams is up to 33% less than a conventional beam with the same dimensions. The manufactured products are lighter and with a significantly stable cross-sectional shape, compared to natural wood beams with the same dimensions. Sawing the peeler cores and obtaining materials with a triangular and trapezoidal cross-section helps to achieve volume yields from 60.6% to 71.1% of the raw material initial volume.
