Abstract

Slates (Texas, Arkansas, Lo.uisiana, Mississippi , Alabama, Georgia, Florida, North Carolina, a,nd Sottth Carolina) a,nd parts o/ ad.iacenl stales. The hnuber industry o/ the Southern Stales has tong operated ,m s~natt, yom~g-growtl~ timber, in conh'ast to the l l'est Coast Stales, which have depended .upon large virgin or old-growth limber. The West Coast lumber ind~tslry is characterized by large mills, the S(n~thern i.nd.~str~J is predominantly by s~nall mills. Today the limber supply situatiort is rapidly changing in the [Vest Coa.st region. Oh//,rowth timber is being replaced b); yo-~.tng-growlh. This chan,r is being re./lected "in manufact-t~.ring processes. Rather than turning to small mills with l w producl volume o~ttpat, as was done years ago in the So1,t.lh, lke West Coast indnst~ 3, is develupiug and adapting 'methods which will prod.,ce a larqe volunze o/ products per day. 31uch effort has beett and ix being direcled to the imt ial breakdown o/ the tog into boards and cants. While s,m~e -ztse is being made o~ the log gang/ranle .saw in the West, as well as in the South. other eqttipment receiving much atte.ntion inchtdes undliple bandsaw and circular saw units and the use o/ combination saws and chip-producing knives in the san~e machine ttnit to produce bolk [~tmber a~d pulp ch@s. Developm.e,~ts which are affecting the mam, t/a.ctu.re o~ htmber /ollowing /he initial breakdown include the .introduction of double-arbor edgers, the increased use of memory, xyslems, parlic~.tlafly lo assist the htmber trimmi~ N and lumber segre,gallon jobs," and the introd~otction r rather comple,v shadowline sj,stems 1o improve the e/ficiencv o~/he htmber edging operation and the cntt.ing o~ shop .,4fades o~ htmber into di~,nensiou stock /or window sash, !~rnit~tre paris, etc. .4 notker aspect o! lhe 1.l.n,nber man~@~ctu.ri~g operation is the rapid growth over the past iew years in the prodztc/ion o/ chips /or p~tlpwood, particleb,,ard, and hardboard /r.m sawmill residues. 7"his market has in turn res~tlled i~t the widespread use o/ mechanized eqwipment at the sawmill /~r removing bar4 /rom the. togs. Tke so/lwood 'l,ene'er and pl3,'~vood indust~2v is becoming more and more a small log ind~tstr_v. This trend has lead to eq'~,~ipme~,~t developme,nts and adaptations /or lhe small logs including high-@eed lathes equipped with rapid lathe loaders. This idea, o/ co'urse, has beeu used for years in parts o~ E~trope. d very recent development in this connection is the equ.ippi.ng o~ a lathe with an oscillating kni/e. .q major empkasis in so/lz~Jood veneer ~nilts is o'n the rechtction o/labor cosls and ,material cosls. :'1 recent innovation which promises to as.~Gt in reducing costs is an automated green veneer clipper system which scans tke movi~g sheet o~ ve~wer /or de~eels, makes decisio'ns, and aclivales the clipper.
