Abstract

A device, especially for cigarette-packaging machines, for joining the payed-out end of a strip, which had been wound into a reel, with the beginning of the strip of another reel. The device includes a buffer or storage device in which a certain length of the strip, which is conveyed over guide rollers, is stored, and out of which that amount of strip which is required for continuous operation is withdrawn during the joining process. The device is also provided with a separating and binding device. In order to provide for replacement of reels in a disturbance-free and semi- or fully-automatic manner at little structural expense, each reel is disposed in a cartridge on the wide sides of which the reel is mounted by means of a spindle which passes through the reel core and extends laterally out of the cartridge. The cartridge is provided with a support surface for the strip beginning of the reel, which is secured against rotation during transport of the cartridge; the strip beginning is held firmly in place on the cartridge. Specific embodiments of the cartridge and of the associated separating and binding device are also provided.
