A method of manufacturing adhesive-backed sheet components having release liners attached to and covering the adhesive backs thereof, and an article made by such method are disclosed. The method comprises the steps of providing an elongate, marginally punched, continuous sheel substrate having a series of consecutive panels that are separable from one another along transverse score lines positioned therebetween; applying a layer of release coating material to a corresponding predetermined minor portion of each of the panels; applying a layer of pressure sensitive adhesive to at least a portion of the layer of the release coating material within the minor portion of each of the panels; applying a sheet component atop the pressure sensitive adhesive within the minor portion of each of the panels to adhere the sheet component to the panel; providing score lines about the periphery of the minor portion of each of the panels so as to allow the sheet component, the pressure sensitive adhesive layer, the release coating layer, and the minor portion of the panel to be removed from the remainder of the panel as an integral laminate unit; and, removing the integral laminate unit from the remainder of each of the panels. The article of this invention comprises the aforesaid sheet substrate having panels thereon each of which is provided with an integral laminate unit thereon that is separable therefrom.
A method of manufacturing adhesive backed sheet components having release liners attached to and covering the adhesive backs thereof, comprising the steps of providing an elongate, marginally punched, continuous sheet substrate having a series of consecutive panels thereon that are separable from one another along transverse score lines positioned therebetween;
An elongate, marginally punched, continuous sheet substrate, comprising a series of consecutive panels that are separable from one another along transverse score lines positioned therebetween, each of said panels including a laminated area thereon covering a minor portion of said panel, said laminated area including a layer of release coating material adhered to said minor portion of said panel, a layer of pressure sensitive adhesive material adhered to at least a portion of said layer of release coating material within said minor portion of said panel, and a sheet component positioned atop said pressure sensitive adhesive layer within said minor portion of said panel and held onto said panel by said pressure sensitive adhesive, each of said panels further including score lines positioned about the periphery of said minor portion of said panel, said score lines being constructed and arranged to allow said sheet component, said pressure sensitive adhesive layer, said release coating layer and said minor portion of said panel to be removed from the remainder of said panel as an integral laminate unit, said integral laminate unit comprising said sheet component, said pressure sensitive adhesive attached thereto, and said release-coated minor portion of said panel adhered to and covering said pressure sensitive adhesive, said minor portion of said panel functioning as a releasable liner on said integral laminate unit, which releasable liner, when removed, exposes the pressure sensitive adhesive attached to the sheet component, facilitating subsequent adhesion of the sheet component to another object.
