INCREASING RESOURCE USAGE EFFECTIVENESS AT PRODUCTION OF OAK PARQUET BOARDS

Abstract

Costs reduction at wood usage during  oak lamella production is  received by the way of reduc-tion in recommended  thickness and width of wet prefabricates. The top layer of  parquet board – a thin cut wood (lamellas) of valuable species, usually with thickness of 3.5-5.0 mm. The results on cost minimizing are given by comparing actual costs and the recommended amounts of prefabricates for the production of 100 m² of lamellas. Reducing the size of prefabricates from 30x78 mm and 30x220 mm correspondingly to 29x75 mm and 29x215 mm make possible to reduce the cost of wood respectively  on 5.85 and 7.59 percent and thus  to obtain economic effect in the manufacture of parquet boards, as well as significantly reduce the unit costs on oak wood.  The given analysis on scattering of the actual size of thickness and width at wet oak prefabricates and lumber, as well as the scattering of the actual values of  wood drying out allowed to minimize lumber nominal sizes  at the lamella manufacture for parquet boards. Implementation of recommendations into production will facilitate to reduce costs per unit of oak wood and receive the economic benefit in the production of lamella parquet.
