Predelava in izkoristek lesa smreke pri delu s horizontalnnim tračnim žagalnim strojem : diplomsko delo - visokošolski strokovni študij = The processing and utilization of spruce wood when working with a horizontal band saw machine : graduation thesis - higher professional studiesSmrečnik, HermanV diplomski nalogi so predstavljeni izkoristki lesa pri razžagovanju debel smreke različnih debelinskih stopenj. Pri tem so pomembne tudi vrste in količine različnih končnih izdelkov, ki jih dobimo ... pri takšni mehanski predelavi. Ugotovljeno je bilo, da so izkoristki lesa sortimentov pri žaganju v določenih primerih zelo visoki, tudi nad 80 %, izkoristki celotnih debel pa do skoraj 80 %. Stopnja koničnosti, kot napaka hlodovine, ne vpliva vedno na izkoristek negativno in je lahko v določenih primerih ta celo višji kot pri nizki stopnji koničnosti. Na izkoristek v veliki meri vplivajo predvsem izkušenost upravljavca stroja, vrste žagarskih produktov ter dimenzije sortimentov. Pri žaganem lesu prevladujejo grede, deske, trami, medtem ko so letve, morali in plohi zastopani v manjših deležih. Količinsko je žagovina zastopana v deblih z okrog 10 % deležem.V večini primerov povprečna debelina skorje z višanjem debelinske stopnje narašča. Tudi delež skorje debel po debelinskih stopnjah se spreminja in v našem primeru znaša 6-8 %.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [H.
