This invention relates to a surface coating device of bamboos including the stays having anti-corrosion, insect-prevention property and produced by said device characterizing that a nozzle having an opening permitting to freely pass natural materials such as bamboos or tree branches whose outside diameter is irregular is inserted in the resin chamber set up adjacent to the cylinder pushing out melted synthetic resin such as vinyl chloride and by passing said natural materials or the materials whose surface has been evenly coated beforehand by chemicals having adhesiveness like tar as well as anti-corrosion, insect-prevention property at a constant speed slowly rotating from backward of said nozzle, said melted resin successively fed in to said chamber adhesively coats the surface of said materials in a state of film.
A continuously and synchronously operated plastics coating device for elongated bamboo poles or the like consists of a plastics feeding unit having a plastics injection unit planted in a perpendicular relationship to a molding member. Plastic is injected thereout in a film state through a round fissure so to coat a continuously forward-moving bamboo pole with a film of plastics. The pole is fed through one end of the assembly and moves into the film of plastics so that a continuous coating process is effected thereby.
A foldable stroller includes: a frame consisting of a pair of handle bars, a plurality of wheel bars pivotally secured to the handle bars having a plurality of wheels rotatably mounted on the wheel bars, a pair of seat bars pivotally connected with the wheel bars for supporting a seat, a pair of bottom struts diagonally pivotally secured on a bottom portion of the stroller and a pair of back struts diagonally pivotally secured to a back portion of the stroller for foldably linking the wheel bars and handle bars; with each bar or strut made of plastic-clad bamboo strip for preventing moisture corrosion, for comfortable seating and ergonomic handling.
An apparatus and a method provide for the extruding of thermoplastic insulation onto complex shapes, such as generator stator bars. The method of the present invention comprises the steps of feeding the complex shape through a central bore of an extrusion die to deposit a thermoplastic coating along the entire length of the shape as the extrusion die traverses the length of the complex shape.
