Abstract
An apparatus (blank unit) for feeding blanks to an article to be wrapped is disclosed. In the feeding of blanks (13) or of a web of material (14) made from critical packaging materials (thin foils), suction conveyors (32 . . . 37) are used which transport, guide and retain the web of material (14). An optimum guidance of the web of material (14) is ensured when lateral elongated suction conveyors (32, 33) reach below a pack track (15). Additionally, shorter suction conveyors (34 . . . 37) are disposed above the pack track (15) in the region of the web of material (14). To adjust the blank unit to different widths of the web of material (14), the lateral elongated suction conveyors (32, 33) can be displaced transversely relative to one another. Moreover, individual shorter suction conveyors (34 . . . 37) can be removed. To adapt the apparatus to different heights of the article which is to be wrapped (group of packs 12), the means which are involved in the positioning of the web of material (14) or the blank (13) are vertically adjustable. For this purpose, a support, in this case a housing (17), to which the means are attached, is movable up and down by a spindle mechanism.
