A method of manufacturing a stencil to get the pattern on the products
(57) Abstract:Usage: to get the pattern on the product stream of abrasive material. The inventive method is that the pattern of the product is first put on the dimensionless mesh stockings, for example of nylon and put on it a layer of polymer material, then the stocking with the polymer material is removed from the template, turn inside out and again put on the template, after which it put a layer of Mylar and a second layer of polymeric material and cut it open along the contour of the pattern. Variants of layers of polymer and Mylar material is applied in the form of an annular bands or in the form of local spots in the areas of application of the pattern. Polymer and Mylar material is applied in the form of an annular bands or rings spray. A second ring of polymer material is carried out with excess of the first ring width, and the stencil form beacons separated at a distance holes. 5 C.p. f-crystals, 10 ill. The invention relates to a stencil manufacturing technology to obtain a pattern on the products mainly three-dimensional form.A known method of manufacturing a stencil to get on the glass pattern jet abrasive ie it resistant to abrasive particle composition .The disadvantage of this method is that it receives the stencil is designed for a single use, which is not economically profitable.In Fig.1 shows a stencil for bulk products installed on the template of Fig.2 - section a-a in Fig.1; Fig.3 - sleeve of mesh material; Fig.4 - install net stocking on the template of Fig.5 - installation ring made of polymeric material on the mesh stocking of Fig.6 - set the template turned inside out net stocking with the first polymeric ring; Fig.7 - install mesh stockings rings made of Mylar material, and Fig. 8 - installation on Mylar material of the second ring of polymeric material of Fig. 9 - version install on a Mylar ring and pinning him stocking of polymeric material of Fig.10 - option stencil for bulk products with variable diameters.P R I m e R implementing the method. Wood (metal, plastic or other material) discs make a template 1 product, such as a lamp has a cylindrical shape, and put on the dimensionless mesh stockings 2 of nylon with sewn edges 3. In the area of drawing on net stockings set PE is with nylon mesh polymeric adhesive or thermal means.In the embodiment, the polymeric material can be applied in liquid form by spraying on net stockings or left nezasciscennyi ring band, for which the template is applied to the material, preventing the adhesion of a polymeric coating to the surface of the template. This material can be graphite or other lubricant. Then the grid with connected with her polymer material in the form of a stocking or the ring is removed from the template, turn inside out and again put on the template in inverted condition. When this pattern contacts the first ring of polymeric material located on top of him on a nylon mesh.After that, on net, in whole or in size of the polymer ring wear ring 5 of the pet nonwoven material, for example Mylar paper, and connect it to the grid and the first polymeric ring similar way. Then on Mylar ring put on the second ring 6 made of polymeric material and combine it with Mylar thermal ring by or through a layer of polymer adhesive.After that, the obtained multilayer material with a knife cut or burn pattern 7 (picture, text, and so on) required to be applied on the product.In a variant of the first material over the entire annular surface of the mesh material, but only in the areas of application of the pattern. Thus it is possible to apply labels, logos or other information on the product.In case of the need to protect products from damage by a stream of abrasive material, the second layer of polymeric material to perform as well as stocking 9, connecting it locally with a Mylar ring.In this case, the stencil forms over the coating area of the pattern unconnected with mesh grip the collar 10 and the skirt 11.In the production version of the stencil for products with variable diameter (bottles, flasks and so on) made a few stencils in a similar way.Manufacturer of stencil proposed method can speed up the process of creating a multi-layered stencil, which allows from 500 to 2000 zabivac drawings stream of abrasive material and a virtually unlimited stream of paint.The stencil does not introduce distortions in the pattern during the entire period of operation and allows you to quickly set the template for the product. 1. A method of MANUFACTURING a STENCIL TO GET the PATTERN ON the ARTICLES comprising the polymer compound layer placed between them a layer of Mylar material and vartanyants by putting on a template products dimensionless mesh stocking, for example, from nylon and then applying to it a layer of polymeric material, and then stocking coated with polymeric material is removed from the template, turn inside out and again put on the template, followed by applying a layer of Mylar material and the second layer of polymeric material.2. The method according to p. 1, characterized in that the polymer layers and Mylar material is applied on the mesh stocking spray in the form of an annular band located in the zone of formation of the pattern.3. The method according to p. 1, characterized in that the polymer layers and Mylar materials put on net stockings in the form of rings and connect them with each other and mesh material thermally or glue.4. The method according to p. 3, characterized in that, for the purpose of protecting the product from abrasive material, the outer ring of polymeric material performs a width greater than the width of the inner rings of material for education unconnected with them protective elements.5. The method according to PP.1 to 4, characterized in that, to form a pattern on the surface of the product with different diameters, the layers of polymer and Mylar material is applied in the form of parallel annular bands formed p is the stencil perform the specified label in the form, at least two located on opposite sides of a pattern of holes to ensure alignment with other stencils.
FIELD: technology for producing thermo-sensitive material for stencil printing forms, engineering of device for producing said material, engineering of stencil printing machines.
SUBSTANCE: material for printing forms is made only from film of thermo-plastic resin by usage of polyether film in such a way, that aperture, through which paint may permeate, can be thermally perforated without increasing power of thermo-printing head. Film is a thermo-sensitive material for stencil printing forms 12, having given thickness, and consists of stretched mylar film or stretched film with low melting point, produced by copolymerization of polyethylene therephthalate and polybutylene therephthalate. A set of smallest raster cells 14 is formed on one side of film by transfer of template. Transfer of template may be performed under working pressure 104·102(m-t)/(m-g) Pascals or higher, when working temperature is t°C, melting point temperature of film is m(°C), and temperature of film vitrifying is g(°C).
EFFECT: decreased power of thermo-printing head, facilitated operations with film.
