DESCRIPTION:
BRIEF SUMMARY
This application is the national phase of international application PCT/GB96/00002, filed Jan. 2, 1996 which was designated the U.S.
This invention relates to a perforated adhesive assembly.
Perforated self-adhesive films have a variety of uses, including providing a-solar shading device when applied to windows. Perforated self-adhesive film may also be provided with a design applied to one side which is not visible from the other side, as described in British Patent No.2165292 and corresponding U.S. Pat. No. 4,673,609. These patents disclose an embodiment in the form of a perforated film or other material, sometimes referred to as a perforated "facestock", a layer of perforated self-adhesive, sometimes referred to as a pressure-sensitive adhesive and a perforated protective film to the adhesive, sometimes referred to as a perforated "liner". The perforated protective film or liner is removed to expose the adhesive prior to application of the perforated facestock to a window or other surface.
The problem with these perforated assemblies is that if paint or ink is sprayed onto the facestock there is nothing to stop the paint or ink from penetrating the perforations leading to the presence of paint or ink where it is not wanted and thus producing a very poor finished product. Further if such a perforated assembly is printed on a vacuum bed, such as is commonly used with screen printing machines, the perforations prevent the perforated material from being held down on the printing bed by vacuum. Moreover the application of the vacuum to the underside of the perforated assembly can positively suck ink through the holes in the perforated material which, as already stated, is undesirable and can also suck ink into the vacuum system itself with very damaging results.
GB-A-224 4585 to Akers discloses a perforated self-adhesive assembly comprising a clear perforated film which is typically printed with a design, a self-cling or self-adhesive layer and a window or other base material. The self-cling or self-adhesive layer may be protected by a peel off backing paper or card, before being applied to the window or other base material.
FR-A-2693950 to Gautreneau discloses a perforated paper with an unperforated backing sheet of paper which is typically connected at only one edge of the perforated paper. The unperforated backing sheet overcomes problems of printing a perforated paper sheet.
Perforated self-adhesive assemblies comprising perforated facestock, a perforated adhesive and an opaque perforated paper liner with an additional unperforated liner have been used in the USA. Typically, the additional unperforated self-adhesive plastic film was adhered to the perforated liner, as a means of overcoming printing problems. Also, a design was typically printed on the perforated facestock to form the product for sale. The perforated liner and the additional unperforated liner were removed together and the imaged perforated facestock adhered to a window by means of the perforated adhesive layer. Such products are believed to have been manufactured by Visual Technologies, Inc. of Pineville, N.C. USA and placed in the public domain not later than September 1993.
Typically in such products, the design was printed "verso" facing a clear perforated facestock and the build-up of applied colouring matter during imaging the design and the finished design were not visible until removal of the opaque perforated paper liner and additional unperforated liner. Thus, the printer or customer could not inspect a product before installation without removing the opaque perforated paper liner and additional unperforated liner, thus amaging the produce for any Subsequent use.
The present invention has been made in order to overcome these problems and provide additional benefits.
According to the invention a method of forming a partially perforated assembly comprising a perforated facestock material, a self-adhesive attached on one side thereof to said perforated facestock material and an unperforated liner having a release surface, said rele
