Abstract

956,119. Pencils. HASSENFELD BROS Inc. Feb. 4, 1963, No. 4543/63. Heading B6P. The greasy lead of a pencil is adhered directly to a wood sheath by an adhesive film of vinyl resin, e.g. plasticized polyvinyl acetate. The polyvinyl acetate may be plasticized with a benzoic acid derivative in the proportions of 80 to 95% polyvinyl acetate and 5 to 20% of benzoic acid acid. In one method of making a pencil, dry vinyl adhesive film is provided within the grooves and upon the adjacent flat areas of a grooved wood sheath formed in two halves. The sheath is assembled with a greasy lead disposed in the grooves and heat and pressure are applied to the assembly to adhere the lead and sheath and the halves of the sheath. U.S.A. Specifications 1,892,508, 1,958,194, 2,098,452, 2,131,657, 2,190,518, 2,228,772, 2,229,633 and 2,515,118 are referred to.
