Description

The manufacture of a hollow toy from a thin fabric is complicated by the question of creating the mechanical strength of such a toy. The elasticity of a hollow toy made of thin fabric can be dried, by applying to its inner surface any kind of reinforcement, its layer which is sufficiently strongly adhering to the fabric in order to maintain this elasticity for a more or less long time.

According to the invention, this problem is solved by pressing a fabric impregnated with an adhesive composition of a preform made of a single layer of fabric with an internal machine seam.

Accurately cut according to the model, sewn on the machine and a toy turned out or sewn inside, if the latter consists of parts, is impregnated through with a light table glue of the following weight ratio: glue 1 part, water 2 parts and powder with finely worn aluminum alum powder ( the surface of the toy completely ceases to be sticky), then the toy is lightly filled with even finely sifted sand, is placed in the appropriate model metal (or from a moisture proof mass) form, in which

the final sanding of all the holes with the same sand is covered with a piece of cotton wool. After that, the form is laid on its side, the top half is carefully removed and, in return, the exact same plaster shape is applied. Then all this is turned over with a plaster half down and carefully remove the second half of the metal. Replacing metal forms with plaster ones eliminates the need to have a large number of metal forms too, especially since the strength of gypsum forms is sufficient for drying products. The dried half of the toy is closed with the corresponding half of the plaster mold, tilting it down and opening the other half of the toy, which until then had not had access to air. Having dried the second half, the toy is taken out completely and is subjected to final drying. The whole process of drying at room temperature lasts no more than 2-3 hours, of which 20 minutes are taken to dry in plaster forms. At higher temperatures, the drying process will be significantly shorter. After the final drying, sand is poured. Then obtained in this way

The toy is filled with a bistro with a drying water-resistant varnish (or with a hot mixture of 2 parts of rosin and 1 part of wax, preferably beeswax, but it can also be artificial) and immediately poured back, letting it flow well. Zatgm toy immersed in a light waterproof lacquer and, allowing it to drain, subjected to secondary drying.

As is well known, a fabric, especially wet, has the ability to be highly stretched. When stuffing with sand, the fabric is freely distributed and easily fills even the smallest recesses in the form, which is clearly facilitated by a regular pattern. The inner side of the fabric has a thin layer of sticky gum-powder of alum does not penetrate there, and the grains of sand, crashing into the glue and resting their hard stops against each other, dry in this position, forming a very elastic durable layer that does not allow us to change when obtained fill the form. In flat places toys, and they are found only in places

the joints of individual parts (e.g., in the doll of the place of attachment of arms, legs) plywood joints are glued in. Toys are very durable: for example, a doll head measuring 6 cm in size with a layer thickness of 1 mm cannot be crushed by the hand of an adult.

The subject matter of the invention.

A method of making a hollow fabric toy by simulating a blank sewn and impregnated with an adhesive composition, characterized in that to create the necessary strength, a sand layer is applied to the inner surface of the toy, fixed with a fast drying varnish, with which purpose the wet modeling is still done in molds by stuffing the latter with sand, which is then poured, the model obtained is dried and filled with a solution of fast-drying varnish, after which the latter is drained and the second dried model is subjected to everyday decoration with varnishes and paint.
