Description
Dotychczasowy wyrób olówków opraw¬ nych w drzewo wymaga krajania drzewa na deseczki odpowiednich rozmiarów, dlu¬ gotrwalego suszenia tych deseczek, zlob¬ kowania ich zapoimoca strugarek (hebla¬ rek), wkladania w zlobki precików grafi¬ towych lub farbowych, sklejania razem dwóch deseczek z umieszczonemi w zlob¬ kach precikami, powtórnego strugania ksztaltowemu frezami na innych, specjal¬ nych strugarkach z których wreszcie de¬ seczka zawierajaca kilka wklejonych pre¬ cików rozpada sie na tylez olówków opraw¬ nych w drzewo.Stosownie do niniejszego wynalazku o- prawa wszelkich precików stanowiacych o- lówek wyrabia sie nie z drzewa jednolite¬ go, lecz z trocin drzewnych, wobec czego Wszystkie wyzej wymienione czynnosci sa zbedne i wyrób znacznie sie upraszcza, dajac przytem moznosc zuzywania tansze¬ go surowca.Trociny i odpadki drzewine ugniecione w plastyczna mase przepuszcza sie przez prase pod cisnieniem w ten sposób, by wy¬ chodzaca z prasy uksztaltowana oprawa trocinowa chwytala wprowadzony w mase precik olówkowy i, oblepiwszy go, wy¬ chodzila z nim razem nazewnatrz.Dalsza obróbka, t. j. zewnetrzne szlifo¬ wanie, politurowanie i stemplowanie pro¬ wadzone byc moze na sposób dotychczas praktykowany przy olówkach oprawnych w drzewo. PLThe hitherto production of pencils framed in a tree requires cutting the tree into boards of the appropriate size, drying these boards for a long time, cracking them from the planers (planers), putting graphite or ink stamens into the grooves, gluing two boards together with with sticks placed in grooves, re-planing with shape cutters on other special planers, of which finally a disc containing a few sticks glued in breaks apart as many pencils framed in a tree. the pencils are made not of solid wood, but of wood sawdust, so that all the above-mentioned activities are unnecessary and the product is considerably simplified, thus making it possible to use cheaper raw materials. through the press under pressure in such a way that the shaped sawdust holder that comes out of the press seizes the a pencil stalk inserted in the mass and, after sticking to it, went out with it together with it. Further processing, i.e. external grinding, varnishing and stamping, can be carried out in the manner previously practiced with wood-bound pencils. PL
