ABSTRACT:
A packaging arrangement for an electrical heater unit adapted for adhesive attachment to a surface, for example, to a window of a motor vehicle. The heater unit includes a plurality of heater strips which have an adhesive coating on one face thereof whereby the strips may be secured to the window. The strips are supported in a desired pattern for application to the window by being adhesively mounted on one surface of a backing sheet. The adhesive coated surfaces of the strips are remote from the backing sheet and a removable cover sheet overlies the heater strips. A clearance is provided between the cover sheet and the adhesive coating on the heater strips so that the cover sheet is not contacted by the adhesive coating on the heater strips. During application of the heater to the window, the cover sheet is first removed, the heater strips carried by the backing sheet are then applied to the window so that their adhesive coating bonds them to the window and lastly the backing sheet is removed leaving the strips adhered to the window.
