Abstract

<P>PROBLEM TO BE SOLVED: To provide a display plate on which a display plate can be printed in the state of a flat plate, which can be manually bent after printing, and can maintain the bent state. <P>SOLUTION: The bending shape holding display plate is composed of a structure obtained by sticking together a metal foil 2 to the rear surface of a soft or a rigid plastic film 1 having a printable front surface and having the tenderness to permit manual bending, and is composed of a structure capable of holding the deformation shape of the display plate by the characteristic of the plastic deformation of the metals stuck together. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a display plate that can hold a deformed shape after being deformed by applying a bending stress.

Display plates to be attached to curved surfaces such as cables and pipes are usually hard types, and it is necessary to print them in a flat state and heat them to a shape that follows the situation or to bend them by press working before attaching them.
In recent years, development of various printers has progressed, and the situation of printing on the display plates on site has increased, and it has been necessary to bend by some means at the site after printing.

  On-site bending is difficult in terms of equipment and processes, and soft vinyl chloride and olefin-based soft display plates have come to be used to eliminate this work.

  However, when the soft display plate is fastened to the cable or the like, only the vicinity of the band follows the shape of the cable or the like, and the other portions are attached while spreading in a form close to the original shape without contacting the cable or the like. FIG.

  Attaching a display plate that does not follow the entire shape of such a cable, etc. is not only an overview problem, but an operator who is doing some work near this display plate hooks this display plate, etc. There was a problem.

  The problem to be solved is that the display plate can be printed in a flat state, can be bent by hand after printing, and has a function of maintaining the bent shape.

The main feature is that a metal foil is bonded to the back surface of a plastic film having a soft or hard printable surface that is soft enough to be bent by hand.
When ABS or PVC is selected as the plastic film, there is no need for surface treatment, but when PP or PE is selected, primer treatment is performed in advance for the purpose of providing a printable surface. By attaching a metal foil such as an aluminum foil having an appropriate thickness to the back surface of the film, it is possible to have a function of maintaining the shape due to the property of plastic deformation of the metal.
Generally, there are products with a metal foil bonded to a plastic film. The thickness composition of plastic films and metal foils is also quite different.

  The present invention can be printed by thermal transfer, an ink jet type printer, screen printing, and offset printing. After printing, it is bent by hand without using a heater or press, and immediately follows the shape of the cable or tube to which it is attached. There is an advantage that it can be installed.

  It is suitable that the thickness of the plastic film portion is about 0.1 mm to 0.8 mm depending on the softness, and the aluminum foil is used as the metal foil and the thickness is about 10 μ to 50 μm. It is necessary to select each thickness according to the diameter of the other party to which the display plate is attached. In order to prevent rubbing between the aluminum surface and the plastic surface, a film may be further applied or coated on the back surface of the aluminum.

  FIG. 2 is a cross-sectional perspective view of one embodiment of the plate of the present invention, where 1 is a plastic film on the front surface and 2 is an aluminum foil bonded to the back surface.

When soft and hard PVC film, ABS film, acrylic film or PS film is selected as the surface plastic material, surface treatment is not required for printing, but when olefin-based PP, PE, polycarbonate, etc. are selected In the surface, a primer layer suitable for screen printing, offset printing and thermal transfer printing is applied to form a printable receiving layer.
When configuring a display plate to be attached to a cable having a diameter of about 10 diameters, the thickness of PE is about 0.2 mm to 0.6 mm, and the thickness of the aluminum foil to be bonded to this film is about 20 μ to 30 μm. The foil configuration is suitable.

  For bonding the PE film and the aluminum foil, a pressure-sensitive curing dry lamination process may be used using an aliphatic adhesive, or a heat-sensitive curing adhesion may be performed using an aromatic adhesive.

  After the laminating process, it is better to further apply a coating or polyester film to the aluminum surface for the purpose of coating the aluminum surface.

After pasting, it is slit in a roll shape so that it can be continuously supplied by a thermal transfer printer, etc., and half-cutting or punching processing is performed on the required shape, or it is punched into a sheet shape so that it can be attached to the printer in a card shape The final product.
When attaching these display plates to a cable, etc. after printing, bend them by hand along a slightly smaller diameter than the cable before attaching them, and then attach them to the cable using a tie wrap band, vinyl band, or double-sided tape. To do.

  FIG. 3 is a mounting view of the plate, 3 is a display plate, 4 is a mounting band, and 5 is a cable.

  The followability to the cable in the central portion is significantly different from that of the conventional soft-envelope plate in FIG.

Since a flat plate can be used during printing, not only a thermal transfer printer but also an ink jet printer can be used as a printer.
Since bending after printing can be done by hand, construction can be performed immediately after printing on site.
It can be used as a display plate for thin tubular objects such as communication cables, power cables, run cables, various communication lines, and various pipes.

It is explanatory drawing which showed the attachment condition of the conventional soft plate. (Background technology) It is explanatory drawing which showed the structure of the bending shape maintenance display plate.
