Abstract
In the production of packs with outer wrappers which have a tear-open strip (12), the latter or continuous material strips (18), for the purpose of severing the tear-open strips (12), are provided with printing, markings (24), etc. Moreover, the film webs (13) are preferably provided with markings, printing or printed marks (25). Sensing elements help to detect the relative positions on account of said printing and the drive of the film web (13) and/or of the material strip (18) is controlled accordingly.
Claims18
Process for producing packs (10), in particular cigarette packs of the hinge-lid type, with an outer wrapper made of (transparent) film and with a tear-open strip (12) applied to the outer wrapper, blanks (11) for the outer wrapper being severed from a continuous film web (13) with tear-open strip (12), characterized by the following features:
- a) a continuous material strip (18) for producing the tear-open strip (12) is provided with precisely positioned printing, markings (24) or the like,
- b) the printing, markings (24), etc. are sensed by a sensor—printed-mark reader (26),
- c) the precise position of the tear-open strip (12) on the film web (13) and/or a severing cut for severing the blanks (11) with tear-open strips (12) from the film web (13) is controlled in accordance with the detected printing, markings, etc.
Apparatus for producing packs (10) with an outer wrapper made of, in particular, transparent film and with a tear-open strip (12) applied to the outer wrapper and preferably likewise consisting of transparent film, it being possible for blanks (11) for the outer wrapper to be severed from a continuous film web (13) with tear-open strip (12) applied thereto, characterized by the following features:
- a) the material strip (18) for producing the tear-open strips (12) is itself already provided with printing, markings (24), printed marks or the like,
- b) in the case of the film web (13), sensors—printed-mark readers (26)—are positioned in the region of the movement path of the material strip (18) connected to the film web (13), or of the tear-open strip (12), for the purpose of sensing the printing, markings (24), etc. on the material strip (18) or on the tear-open strips (12),
- c) the sensors—printed-mark readers (26)—are connected to an evaluation unit for evaluating the detected positions of the printing, markings (24), etc.,
- d) drive elements for the material strip (18) and/or the film web (13) can be controlled by the sensors or printed-mark readers (26) via the evaluation unit.
Reel for material strips (18) for the production of a tear-open strip (12) to be attached to a blank (11), with the material strip (18) drawn off the reel is laid on a film web (13) and it being possible to sever the blanks (11) with tear-open strip (12) from the latter, characterized in that in order to feed two material strips (18) to one film web (13) (each) the two material strips (18) are wound on a common carrier, in particular on a common reel shell or on a common reel core (63).
