Method for manufacturing substrate-integrated gasket
10391689 · 2019-08-27 · ·

The invention provides a method for manufacturing a substrate-integrated gasket, the method integrating a fiber substrate which is constructed by a pulp fiber having cellulose as a main component and a gasket body which is constructed by a rubber-like elastic body according to a rubber impregnation, wherein a plurality of substrate-integrated gaskets are obtained by executing an injection molding by plural stages of rubber metal molds. Further, the rubber material is filled in plural stages of metal mold cavities by passing the rubber material through the fiber substrate in which a rubber material flow channel in the metal mold is closed at its injection pressure. The invention can reduce a man hour for removing burr and cleaning a metal mold by suppressing generation of rubber burr at the molding time and can reduce an amount of disposal of a molding material, thereby achieving a good manufacturing efficiency.

Creation of a transparent window in a security substrate for security printing applications

There is described a method of creating a transparent window (W*) in a security, especially paper, substrate (1) for security printing applications, the method comprising the steps of (i) providing a security substrate (1), (ii) forming an opening (10*) into and through the security substrate (1), and (iii) filling the opening (10*) with transparent material (2) thereby forming the transparent window (W*). The filling of the opening (10*) with the transparent material (2) is carried out in a state where the opening (10*) is open on both sides of the security substrate (1) and extends through the security substrate (1), the filling of the opening (10*) including the application of a first side (I) of the security substrate (1) against a supporting surface (21A) of a supporting member (20, 21) in such a way as to block one side of the opening (10*), while the transparent material (2) is applied inside the opening (10*) from the other side (II) of the security substrate (1). Advantageously, the method further comprises the step of forming a field of lenses (L) on one side of the transparent window (W*), in particular by replicating the field of lenses (L) directly into the transparent material (2) filling the opening (10*). Also described is a suitable device designed to fill the opening (10*) with the transparent material (2).
