Abstract

PURPOSE: To provide a method and an apparatus for transferring a decoration to an object having surface of arbitrary shape including planar surface. CONSTITUTION: A ground paper 13 having an insulation layer 11 on one side and a decoration 12 on the other side is set such that the one side touches a first expanding/contracting film 3 fixed to the frame 1 of a decoration transfer unit. Objects 14, 14' of arbitrary shape are placed on the ground paper 13 and covered with another ground paper 13' applied with an insulation layer 11' on the side opposite to a decoration 12' such that the opposite side is directed to a second expanding/contracting film 4 fixed to the frame 2 of the decoration transfer unit. When the decoration transfer unit is closed such that the insulation layer 11' touches the second film 4 and the pressure in the space including the objects 14, 14' is reduced, the ground papers 13, 13' come into tight contact with the objects 14, 14'. When it is heated under that state, the decoration 12, 12' can be transferred to the objects 14, 14' through sublimation.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transferring a pattern printed on a piece of paper to an object of arbitrary shape by sublimation, and an apparatus for carrying out the method.

0002

BACKGROUND OF THE INVENTION A known machine for carrying out the above method is according to European Patent Publication No. 0 252 610:
The device generally consists of a rigid base and a cover with a plurality of holes so that once the cover is closed, the surface of the object to be decorated does not protrude. The object is placed on the bottom of the platform, while the paper strip containing the decoration to be sublimated is placed on top of the cover and on the surface to be decorated. A deformable artificial coating expands and contracts over the top of the device, so that when the device is placed in a vacuum, the paper strips to be sublimated stick over the surface of the object. The entire device is placed in an electric kiln under reduced pressure, and the design is sublimated to a depth of several millimeters.

SUMMARY OF THE INVENTION The sublimation decoration methods commonly used in the prior art are effective only for flat objects or very slightly raised objects. Otherwise, the paper strip covered with a layer of material to be sublimated will wrinkle, which is an unacceptable defect in the appearance of the decoration. Moreover, traditional machines can decorate objects by
This cannot be done on every surface of an object.

The present invention overcomes the drawbacks listed above and
More particularly, the object of the present invention is to provide a method that can sublimate a pattern onto any surface of an object of any shape, regardless of whether the temperature is high or low, and an apparatus for carrying out the method.

BRIEF DESCRIPTION OF THE DRAWINGS The features of the invention and the advantages obtained thereby will be better understood from the following description taken in conjunction with the accompanying drawings, in which: FIG.

The decorative transfer device shown in FIG. 1 has two frames 1 and 2, which are made of rectangular aluminum, one of which is fixed and the other movably connected to one. .

[0008] Airtight thin and stretchable membrane 3, 4
are fixed to the lower surfaces of frames 1 and 2 by adhesive or other means. A suitable material for the membranes 3, 4 is, for example, silicon acetate, which is highly resistant to high temperatures and can be expanded and contracted to be greatly deformed.

The frame 1 is provided with a flat packing 5 for airtightness made of the same material as the membranes 3 and 4 on the upper part, and the frames 1 and 2 are provided with a plurality of gaskets attached to the frame 1. With lock 6,
They are connected in such a way that when pressed together they form a completely sealed relationship. These locks 6 have a clasp cooperating with a handle 7 mounted on the frame 2, which clasp may take a form similar to the clasp of an ammunition box.

A tube 8 extending to a vacuum pump 9 projects from the side edge of the frame 1. The tube 8 opens into a groove 10 formed inside the frame 1 in order to distribute the reduced pressure moderately over the circumference of the closed device.

The first step of the first decorative transfer method according to the invention is carried out by gluing an insulating layer 11, such as an aluminum foil, onto one side of a mount 13 made, for example, of a piece of paper. The opposite side of the mount 13 is covered with a decoration 12 consisting of a layer of material to be sublimated. This step is not carried out except in the case of sublimation at high temperatures, in order to avoid dissipating the color of the decoration 12 to the outside.

The second step, as shown in FIG. 2, is to place the mount 13 on top of the membrane 3 so that the insulating layer 11 made of aluminum foil is in contact with the membrane 3.

Next, at least one object 14 is placed on the mount 13.
Place it on top. In the example shown in FIG. 2, two objects 14 and 1
4' are placed side by side.

Furthermore, the objects 14, 14' are placed on another mount 13', so that the decoration 12' to be sublimated is in contact with the object, while the insulating layer 11' made of aluminum foil is placed on the side of the membrane 4 of the frame 2. Cover so that it is located.

The frame 2 is closed onto the frame 1 using the lock 6 and the handle 7 to obtain a completely sealed relationship between the flat packing 5 and the membrane 4.

The vacuum pump 9 is activated to place the decorative transfer device consisting of the two frames 1 and 2 under reduced pressure. As a result, the films 3 and 4 are sucked in and are forced to cover the mounts 13 and 13', and the decorations 12 and 12' are stuck to the entire outer periphery of the objects 14 and 14' (see FIG. 3).

The device under reduced pressure is placed in a conventional electric kiln with a resistor 15. At this stage, each mount 13, 1
The decoration 12, 12' of 3' sublimates and penetrates several millimeters over the entire surface of the object 14, 14'. The residence time of the device in the kiln is determined depending on the material of the object 14, 14' to be decorated, without causing any damage.

When the materials of the objects 14, 14' cannot withstand long-term retention due to the risk of deformation, the frames 1 and 2 of the apparatus are left under reduced pressure, and as shown in FIG. solid frame 1
It is preferable to put it in a bag 101 attached to 01.

The bag 100 is made of a similar material as the membranes 3 and 4 of the device, namely silicon acetate, which can withstand high temperatures as well as large deformations. The bag 100 is then submerged in a heated oil tank 102 filled with oil 103 whose temperature is maintained between 200 and 250 degrees Celsius via a resistor 104 . The bag 100 submerged in the heated oil tank 102 is deformed by the pressure of the oil 103 and sticks to the outer periphery of the membranes 3 and 4 of the device. This modification changes the temperature between the mounts 13, 13' and the object 14.
, 14' directly onto the surface of the object 1 and the decoration 12, 12'
Transfer to the entire surface of 4,14'. This transition is achieved in a few seconds and without causing any deformation of the object, the decoration 12, 12
' to be completely regenerated.

When the device is opened and the mount 13' remaining stuck to the insulating layer 11' is taken out, the decoration 12' becomes the object 14,
14' is permanently attached to a portion of its periphery.

Next, when the paper piece 13 remaining stuck to the insulating layer 11 is taken out, the decoration 12 has been transferred to the remaining portion of the object 14, 14' that is not decorated by the upper decoration 12'.

In order to carry out the transfer of decoration by sublimation to objects that cannot withstand the temperature rise required for the application of the above method, the following low temperature transfer method is applied.

It is assumed that the mount or piece of paper with the decoration to be sublimated has an insulating layer 1 made of aluminum foil.
1,11'.

First, a cloth 16 impregnated with a solvent is placed on the membrane 3 of the frame 1 of the apparatus (see FIG. 4).

The mount 17 and its decoration 18 are moistened with water.

Place the mount 17 and decoration 18 on the cloth 16,
The side on which the decoration 18 is not printed is brought into contact with the cloth 16.

at least one arbitrarily shaped object 14,
14' is placed on the mount 17.

[0027] The objects 14, 14' are placed on another mount 17'.
Then, the decoration 18' is covered so as to be in contact with the objects 14, 14'.

Another cloth 16' soaked with the solvent is placed on the mount 17'.

The frame 2 is closed onto the frame 1 using the lock 6 and the handle 7 to obtain a completely sealed relationship between the flat packing 5 and the membrane 4.

The vacuum pump 9 is activated to place the decorative transfer device consisting of the two frames 1 and 2 under reduced pressure. As a result, the membranes 3 and 4 are sucked in and forced to cover the mounts 17, 17', and the decorations 18, 18' to be sublimated are transferred to the object 14.
, 14' sticks to the entire outer periphery.

While the device is under vacuum, the decorations 18, 18'
is dissolved by the solvent soaked into the cloth 16, 16', so that the decoration 18, 18' is transferred to the circumferential surface of the object 14, 14'. Of note is the fact that when the mount 17, 17' is moistened with water, it retards the transfer of solvent to the decoration 18, 18'. The design of the decoration 18, 18' is not destroyed by this solvent, and the solvent does not cause anything other than sublimation of the decoration onto the object. The last step is to open the device and remove the cloth 16.
, 16' and then the pieces of paper 17, 17'. The decoration 18, 18' is permanently connected to the object 14, 14'.

[0032] The decorative transfer process can thus be carried out regardless of whether the temperature is high or low, and the same machine is used in carrying out the process.

[0033] A decoration method performed using such a device can realize decoration of the entire circumference of an object of any shape as required.
