<p>A manufacturing process of Christmas tree decorations where glass half-products (1) are first blown to required shape of the Christmas tree decoration fitted with a process stem. This glass half-product (1) is fixed into the rack and placed into the metal coating device, where, under vacuum conditions, a thin layer of metals and/or their alloys with thickness 1 to 7 microns is coated on its surface by vacuum plating or vacuum powder coating processes. The metal-coated surfaces created this way are finished in various colours using clear and colour varnishes either glossy or matt. The glass half-products (1) for Christmas tree decoration may be provided with shading in the place of intended decor before the half-product is put into the vacuum metal-coating device. After the shading elements are removed, clear non-coated spots are created on the decoration surfaces. The rack accommodating the glass half-products of decorations is for their placement into the metal-coating device when above methods are performed consisting of a plastic or metal channel (2) into which at least one flexible shading fixture (3) with at least one cavity (4) is placed. The flexible shading fixture (3) is fixed in the metal channel (2) by strutting between its side tags. The channel (2) is in its longitudinal axis provided with two side pivots (6) for the accommodation into the journal bearings positioned on the opposite sides along the perimeter of the working rotating drum (7) of the vacuum metal-coating device.</p> |
