(57) The invention relates to a method of manufacturing a parquet slab base structure
consisting of wood laths (1a, 1b) with a substantially uniform length, a substantially
uniform thickness and a substantially uniform width, which laths are set to extend
longitudinally, laterally parallel to each other in the lateral plane, at a given
side-by-side distance from each other, and which, on one lateral face, are attached
to a binding sheet (2 and 2', resp.) extending substantially over the faces. The wood
laths are obtained by providing sawn timber having a double lath height and a multiple
lath width, at alternating positions on opposite sides, with longitudinal, adjacent
grooves (3, 3') substantially perpendicular to the faces, which extend at least to
the depth of intersection. The grooved sawn timber is set into a flat lay-up side
by side, and a binding sheet is attached to both faces of the sawn timber. The lay-up
with the binding sheets is cleaved at the intersecting or overlapping depth (4) of
the grooves.
