Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing loose letters made by electroforming and for attaching them to products. More specifically, in the production of metal loose letters by electroforming, the discarded electrodeposited material provided to prevent excessive electrodeposition at the outer edge of the letters is used as a mask for applying adhesive to the letters and then thrown away. This invention relates to a method for manufacturing rose letters by electroforming. Excessive electrodeposition at the outer edge of the letters will spread out considerably if there is no waste electrodeposition, but if there is waste electrodeposition nearby, it will also be electrodeposited there.
Electrodeposition at the outer peripheral edge of characters becomes small and does not become excessive. Conventionally, it has been extremely difficult to line up and attach loose letters, etc. that represent a brand, etc. to a product because it involves arranging them in a predetermined order and applying adhesive only to the letters.

The present invention improves and simplifies this process and provides a method for manufacturing loose characters that allows the relative positional relationship of the characters to be accurately attached to the product.

The process will be explained below. As a first step, a resist 2 is applied to a metal plate 1 (for example, stainless steel) by photo printing or the like. As a second step, it is subjected to electroforming. As shown in the drawing, a sacrificial electrodeposited material 4 is applied next to the electroformed material 3 that will become the central character, so that the thickness of the desired loose character 3 is made uniform. As the third step,
Using a vinyl tape 6 or the like with a weak adhesive 5, connect the electroformed product 3 and the electrodeposition 4 to the resist 2 and the metal plate 1.
away from. At this time, the electroformed rose letters maintain their relative positions accurately. As a fourth step, a strong adhesive 7 is applied to the peeled surface by spraying or the like. Of course, this is not limited to spraying, and other methods may also be used. As a fifth step, the sacrificial electrodeposit 4 is peeled off and removed. this is,
This is a non-required character, so discard it. By applying a one-dimensional spray and discarding it as a mask, thinning out the electrodeposited parts, it is possible to obtain individual electrodeposit. In the sixth step, the remaining letters are attached to product 8 to be sold. Then, the letters will be aligned and attached. As a modification of the sixth step, the product produced in the fifth step may be stored with a release paper 9 applied thereto, and the release paper 9 may be removed at the next location to add letters to the product.
In the sixth step, electroforming 3 is adhesive 5 of vinyl tape 6.
It is pulled by both the adhesive 7 and the spray adhesive, but the adhesive 7 is stronger and sticks to the product.

If adhesive is sprayed over the entire surface without a mask of discarded electrodeposition, etc., there is a drawback that when the rose letters are pressed onto the product, some of the strong adhesive that has adhered to areas other than the rose letters will stick to the product. The present method does not have this drawback. One of the features of the present invention is that wasteful electrodeposition is highly utilized and discarded together with the adhesive. As an example, a photoresist was formed around the letters to a width of 0.3 mm on a 0.3 mm stainless steel plate using a known method, and a weak pressure-sensitive plate adhesive film electrodeposited to a thickness of about 50 microns using a nickel electroforming bath was placed on top of the photoresist. I crimped it, and then peeled off all the electrodeposit from the stainless steel plate. Next, after spraying a strong pressure-sensitive plate adhesive over the entire surface, only the discarded electrodeposit was peeled off and this was applied to the product, with very good results.
