PROCESSING BLANKS IN THE MANUFACTURE OF PACKAGING

摘要

An apparatus (10) for processing packaging blanks includes an applying device (40), a first conveyor (26) and a second conveyor (50). The first conveyor conveys the blanks at a first velocity arranged to permit the application of an adhesive to the blanks by means of the device (40). The second conveyor is arranged to receive the blanks from the first conveyor and convey them at a second velocity which is greater than the first velocity resulting in a change in the pitch of the stream of blanks conveyed by the conveyors. Alternatively the applying means may apply an adhering element such as a coupon or hologram such that it adheres to the blank. The adhering element may adhere to the blank by virtue of an adhesive carried on a rear surface of the element or by means of an adhesive carried by the blank. In a twin track system, the pitch change can be utilised to permit the combining of two streams into one. The apparatus are particularly suitable for use in the manufacture of packaging, such as cartons, for cigarettes.
