Abstract
A method and an apparatus for making packets from packaging sheets, especially for cigarettes or the like, which method involves folding or wrapping a preshaped packaging sheet (1), for example of paper or carton board, the packaging sheet (1) having parts (101, 101', 201, 201') for laying over each other, to at least one of which contact surfaces the adhesive is applied in order to fix the parts to each other. In order to fix the parts (101, 101', 201, 201') to each other a cold adhesive is used, that is an adhesive which is fluid at ambient temperature, whereas in order to hold said parts (101, 101', 201, 201') laid over each other in the formed condition of the packet, while the cold adhesive is drying, at least one spot of adhesive consisting of a hotmelt adhesive is applied to at least one of the opposing surfaces of at least one of the associated parts (101, 101', 201, 201') and in an area (17) not coinciding with the area (16) to which the cold adhesive is applied.
