METHOD OF APPLICATION OF COATING ONTO CANVAS OF ELASTIC MATERIAL AND DEVICE FOR ITS ACCOMPLISHMENT Russian patent published in 1995 - IPC

FIELD: application of coatings, in particular flue onto canvas of elastic material. SUBSTANCE: use is made of a template with elastic embossed sections. The sections conform to the shape of workpiece outlines smeared on canvass. Prior to application of glue onto the material canvas, the elastic template is placed under canvas to shaped the canvas sections to be coated with adhesive into configuration of the outline being smeared. At displacement of canvas displacement of the elastic template and friction rubbing-in glue onto the embossed sections of canvas of the moving material by glueing roller are accomplished. The roller rotates at a speed exceeding the speed of displacement of material canvas in relation (1.2 to 1.3):1.0. In canvas section before the zone of smearing canvas to be smeared is pressed to the elastic template so as to hold the canvas from shift relative to the elastic template. The device for application of coatings is provided with a closed elastic template secured on the conveyer belt, the template has embossed sections projecting over the template surface, which conform to the workpiece outlines to the smeared on elastic material. An additional pressure roller is installed above the tension reel. The pressure roller is mounted for rotation in sliders. The bottom of the bath for glue is made with a square opening extending in a shift relative to the vertical axis of the glueing roller. The edges of the bath side walls on the side of this roller extend concentrically to its cylindrical surface. Guides are secured on the bath side walls at an angle to the vertical axis of the glueing roller. Spring-loaded limiting cheeks in the form of fluoroplastic plates are mounted in the guides for movement. Their working edges correspond to the surface of the glueing roller. The calibrating blade drive is made in the form of a horizontal roller secured on the frame in rotation bearing. It is mounted in parallel with the glueing roller. Mounted on both sides of the horizontal roller are bevel gearings that are connected with the calibrating blade by means of screws. A knob with a readout means is coupled with the horizontal roller. EFFECT: facilitated procedure. 3 cl, 4 dwg
