摘要:
The invention describes a device (1) for producing bags preferably for the most part consisting of paper. This device comprises a perforation apparatus (6) for transverse perforation of a material web (3), a hose forming apparatus (9) for forming a hose (10) from the material web (3), a separation apparatus for separating individual hose sections (12) and an apparatus for forming a bottom at one of the ends of the hose section (12). At least one additional tear-away device (11) is provided for tearing away individually material sections from the hose sections (12) or from the bags.

The invention describes a bag machine for producing bags from paper material, comprising: - an unwinding device for unwinding a paper web material and feeding it in a transporting direction (x), - a means of producing weakening lines which follow a course in which some of, or parts of, these weakening lines are offset in relation to one another in the direction (x), and a first wall of the finished bag therefore continues by way of at least one flap which extends beyond the second wall, - a flexible-tube former for forming a flexible tube, in which the side regions of the web can be folded over to form an overlapping region and can be connected to one another, - a severing device for severing flexible-tube portions from the flexible tube along the weakening lines, and - a base-forming device, in which regions of the leading end of the flexible-tube portion can be folded over and fastened on an outer wall of the flexible-tube portion. A device for applying areas of adhesive to the paper material is provided, and this device can be used to apply a respective area of adhesive to a region of the paper material which, in the finished bag, constitutes that side of the flap which is directed towards the second wall.

The invention relates to a device (1) for vertically placing flat workpieces (3, 3') on a stacking table (4). In said device (1), the flat workpieces (3, 3') can be conveyed by a conveying cylinder (2) and can be dropped onto the stacking table (4). The leading ends of the flat workpieces (3, 3') are retained on the outer circumference of the conveying cylinder (2) with the aid of holding means and can be released before the workpieces (3, 3') reach the stacking table (4). Stripping means (5) are provided which encompass a plane (7), strip the workpieces (3, 3') released by the holding means from the outer circumference of the conveying cylinder (2), and deflect the workpieces (3, 3') along said plane in the direction of the stacking table (4). Additional holding fingers (10, 11) which allow the flat workpieces (3, 3') to be kept at a distance from the stacking table (4) can be introduced into the conveying path of the flat workpieces (3, 3'). Said holding fingers can be retracted behind the plane of the stripping means when the flat workpieces (3) are to reach the stacking table (4). The inventive stacking table (4) can be displaced relative to the conveying cylinder (2) along the plane (7) of the stripping means (5), in the direction of travel of the flat workpieces (3, 3').

The invention relates to a bag (10) comprising a front wall (11) and a back wall (12) arranged parallel to the front wall (11), a bottom (13) that can be folded into the plane of the walls (11, 12), such that a filling chamber (14) results that is open on one side, and a pair of carrying handles (31) that is attached on the front wall (11) and the back wall (12). According to the invention, the pair of carrying handles (31) comprises a folding line (15) in the filling space (14), such that the pair of carrying handles (31) can be brought into a usage position (1) and in a rest position (2), wherein in the rest position (2) the pair of carrying handles (31) is entirely folded back inside the filling chamber (14) and in the usage position (1) the pair of carrying handles (31) protrudes at least in certain areas from the filling space (14).
