Machine 2 and associated method for making a bag bottom "B" by starting from a single tube-shaped sheet "F". Said machine comprises: at least one opening element 21 for spreading apart the tube-shaped sheet "F", which is positioned between a first portion "s1" and a second portion "s2" of the sheet "F"; at least one actuating device 3 for moving said first portion "s1". Said machine further comprises at least one first striker element 22 for defining a first folding point for making a first side "11" of the bag bottom "B" after said first portion "s1" has been moved, and at least one second striker element 23, inclined by an angle "a" relative to said first element 22, for defining a second folding point for making a second side "12" of the bag bottom "B" after said first portion "s1" has been moved.

Die Erfindung beschreibt eine Vorrichtung zur Herstellung von Säcken aus Sackhalbzeugen, vorzugsweise aus Schlauchstücken (47), mit welcher Säcke unterschiedlichen Formats herstellbar sind. Diese sind mit zumindest einer Einrichtung zum Falten der Sackböden und zumindest einer Beleimungsstation zum Beleimen zumindest der Bodenklappen (31, 32) des geöffneten Bodenquadrats (30, 45) der Sackböden ausgerüstet, wobei mit der Beleimungsstation Leimspuren unterschiedlicher Abmaße zumindest auf die Bodenklappen (31, 32) aufbringbar sind. Die Beleimungsstation ist mit zumindest einem Auftragskopf (1) ausgestattet, wobei zumindest ein Auftragskopf (1) einen Leimauftragsbereich (37, 38) besitzt, dessen Ausdehnung in einer Raumrichtung (y) veränderbar ist, wobei wiederum zumindest einer der Auftragsköpfe (1) relativ zu den anderen Auftragsköpfen (1) bewegbar ist. Der maximale Auftragsbereich zumindest eines Auftragskopfes (1) in der einen Raumrichtung (y) ist kürzer als der Abstand (C), der sich auf einer Seite der Bodenmittellinie (35) zwischen dem äußeren Rand (31) der Bodenklappe des größten in der Beleimungsstation beleimbaren Sackformats und der Mittellinie (35) des Sackes ergibt.
摘要:
The invention relates to a device (1) for producing sacks from tube pieces, comprising: a transport device (45) by means of which the tube pieces can be transported in a transport direction (x) transverse to the direction of extent (z) of the tube pieces, to processing stations (8, 9, 10, 11); a base opening station (8) by means of which open end segments can be generated by folding over regions of at least one wall of the tube piece about folded base edges at at least one end of the tube piece; a closing station by means of which the open base rectangles can be closed to form bases by folding over parts of the walls and/or tabs about further folded edges of the open base rectangles; an embossing device (26, 26') by means of which at least one part of the base folding edge and/or the further folded edges can be embossed into the tube pieces and which comprises an embossing element (28) and an associated counter element (29); and a folding device by means of which areas of both walls can be folded over about the folded base edges by greater than 90 degrees, in order to be able to bring the embossing element (28) and the associated counter element (29) into contact with the same wall of the tube piece.

The invention relates to a device (64) and to a method for processing semifinished bag products (24) and a gluing station (3, 4) for semifinished bag products. Experience has shown that in particular more complicated semifinished bag products - such as hose pieces having folded open bottom squares and here in particular having folded open bottom squares and already inserted valve slips - tend to be incompletely glued or even to become damaged in a nozzle gap during gluing. Said problem is solved in that at least one feed element (33) is provided that is mounted upstream of the gluing gap in the transport direction of the semifinished bag products and that together with the guide element (33) defines a feed area (41) of the semifinished bag products to the applicator head, wherein at least components of the semifinished bag products can be guided through the feed area, and wherein the feed area tapers in the transport direction (Z) of the semifinished bag products.

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 device for opening tubular bag shapes which are open at at least at one end, comprising at least one slide which can be introduced into an open end of a bag between the bag walls, in order to at least partially fold over at least one end area of a bag wall. According to the invention, the at least one slide (3) can be moved in and out of the bag end to be opened by means of at least one, driven cam (9) which can be moved along a predetermined path (8) and which engages with the slide (3). The slide (3) preferably takes a circular path (4), said circular path comprising a section which runs parallel to a bag-transporting device. The speed of transportation of the bags (2, 2a) on the conveyor device (1) and that of the slide (3) around the circular path are equal.
