Bangles Velvet Machine

Each individual slat goes through a machine called the Groover Machine (not to be confused with someone who can't stop dancing) that cuts — you guessed it — grooves into the surface of the wood. This preps the wood for graphite.Pencil technologies involve advanced design techniques, the preparation and purification of graphite, the mixing of graphite with various clays, the baking and curing of the lead mixture, its extrusion into leads, and the preparation and finishing of the wood casings.Graphite is used to make the writing cores of pencils. Wood (Softwood) Softwoods are coniferous trees, such as pines or spruces. Cedar wood is most commonly used in pencil production. The wood encases the graphite, making it easier for the writer to hold.
