Definitions

  • the invention relates to a writing or drawing pen with a covering and a lead arranged therein, and optionally further elements and methods for its production.
  • Pens or crayons usually have an envelope made of wood or plastic.
  • foamed plastic shafts are also known which are produced in the extrusion or in the co-extrusion process.
  • Wood-cased pencils on the other hand, are generally made from grooved boards, while loose or rigid plastic envelopes are usually produced using the injection molding process.
  • the casing of a writing or painting pen the lead of which is firmly glued into the casing or is arranged such that it can be adjusted axially, in particular by means of a sliding, rotating or pressing mechanism, entirely or predominantly of wood flour, ground wood and / or paper or paper mache.
  • Wood flour is understood to mean very finely chopped wood, for example also sawdust, which is often obtained as a waste product in wood processing.
  • Wood pulp - also called pulp - usually consists of under 0.2 mm wood fibers, which are "sanded” with the addition of water (mostly spruce) pieces of wood using large coarse grindstones.
  • Paper or paper mache is usually a plastic mass made from waste paper, wood or straw, clay, plaster, diatomaceous earth, glue or starch, which can be pressed into oiled molds after soaking with hot linseed oil and / or a zinc chloride solution.
  • wood or bone glue preferably a dispersion adhesive, can advantageously be added to the base mass, as required.
  • Additions of fillers and / or propellants can also have a particularly positive effect on stability, weight and sharpenability.
  • the leads are firmly connected to the casing, in particular glued and easy to sharpen.
  • the leads here, i. d. R. by mechanical actuation of a feed element, axially displaceable or adjustable.
  • pens according to the invention can usually be produced using the same production processes and in many cases also using the same systems and devices as are currently used in the production of conventional wooden or plastic pens.
  • the envelopes can also advantageously be produced in the extrusion or extrusion process, in particular also in the co-extrusion or in the duo extrusion process, in each case in the same way continuously or discontinuously together with the lead.
  • the basic mass of the coverings is first processed by means of compression molding, extrusion molding or extrusion to give "customary pencil boards” - unslotted or already pre-grooved - further production can be carried out essentially in the same way as before.
  • This means that the "boards" are half-shells for several pens, possibly grooved, coated with glue, coated with leads, mutually glued and separated, then the individual pens are ground, polished, or varnished and sharpened.
  • the envelopes, or the pins in general, or if necessary for final completion on the circumference or externally ground, polished, varnished and, if necessary, otherwise provided with a smooth and / or colored surface.
  • a coating of rubber, plastic or paper, which may be prefabricated in a tubular or tubular manner, can also be applied to the covering in a particularly advantageous manner.
  • envelopes according to the invention can also be used or serve in any modification as shafts for practically any type of writing or drawing devices.

Abstract

La présente invention se rapporte à un crayon pour écrire ou peindre comportant une gaine (1) dans laquelle est disposée une mine (3), ainsi que, le cas échéant, d'autres éléments, la gaine étant entièrement ou presque entièrement en papier mâché, en farine de bois et/ou en pâte mécanique. En outre, l'invention se rapporte à des procédés pour la fabrication de tels crayons, la fabrication devant se faire en particulier par coulage ou par moulage par injection, par moulage sous pression, ou bien par extrusion ou boudinage.
