Definitions

• the invention relates to a device for producing bags according to the preamble of claim 1 and to a method for producing bags according to the preamble of claim 11.
• German Patent DE 720 665 discloses a machine for producing flat or side-folding bags, in which a material web is unwound from a roll, folded into a tube and separated into individual tube pieces, which are then provided with a bottom.
• a web is first provided with transverse perforations, wherein at each perforation individual perforation sections are offset in the direction of travel of the web relative to other sections.
• this offset perforation results in parts of the rear wall projecting beyond the front wall at one end of the tube section.
• This over the front wall going beyond part of the rear wall is also referred to as a tab.
• the front wall towers over the rear wall at the other end.
• the perforation is designed so that at the leading end of the hose section, the rear wall projects beyond the front wall. This procedure is chosen because then easily folded back the tab and attached to the front wall, for example, glued, can be.
• bags have been increasingly requested in which a strip of transparent material is longitudinally incorporated in the front wall.
• the folded back wall on the front wall is usually printed, since in comparison to conventional bags, the printable area on the front wall is lower overall.
• the device described operates very slowly compared to devices for the production of conventional bags. Also, the separated part can often not be removed reliably, so it can lead to malfunction of the machine to stoppages. The setting of the three mentioned pairs of rollers to each other is very difficult. In addition, the required speed differences often create problems and limit the possible section lengths.
• the object of the present invention is therefore to propose an apparatus and a method for the production of bags, wherein a material part of the front wall is removed, which overcomes the mentioned disadvantages of the described device of the prior art.
• the object is achieved by a device comprising the characterizing features of claim 1, and a method having the characterizing features of claim 11.
• At least one additional tear-off device is provided, with which individual material sections can be torn off from the tube sections or from the bags.
• the basic idea of the present invention is basically not to change the separating device for separating individual tube sections of machines for the production of conventional bags in comparison with the described machine known from practice.
• a further separating or tearing device is provided in order to be able to separate the material section.
• This further tear-off device operates independently of the first separating device for separating individual Hose sections, but after the sameêtsphnzip. It can even be identical to the first separator. The separation of a hose section from the hose and the separation of the material section thus takes place in two separate steps in two separate stations.
• the processing speed which is known from machines for the production of conventional bags, can be maintained, since not only the separating device for separating individual tube sections can be operated at this speed, but also the additional separating device.
• a device according to the invention operates much more reliably, since no complex, the torn-off material portion removal device must be provided within the first separator.
• the material section can be removed from one of the rollers separating the material section.
• An essential feature is therefore that the material section is only torn off the tube section or even from the bag when it has left the first separator. It is preferably torn from a bag or hose portion of the material portion which runs in front of a separation section just isolated hose section or a to be singulated in the separator hose section.
• the bag or hose portion from which the material portion is torn off may directly precede the latter hose portion, or other lengths of hose may pass therebetween.
• a gap is characterized in that no components of the first tube section or the first bag with components of the subsequent tube section or the subsequent bag overlap.
• the material section to be separated from the section of tube which is in progress does not overlap with the tab of the following tube section which is in advance.
• the additional tear-off device of the device for molding the soil is particularly easy from a Construct apparatus for making conventional bags by coupling an additional tear-off device.
• the additional tear-off device can be produced, for example, as an additional module, which can optionally be offered and sold or even retrofitted later. If such an additional tear-off device is present at said position, it can also be put out of operation if conventional bags are to be produced.
• a device according to the invention can therefore also be used very flexibly when it comes to producing different kinds of bags.
• a device manufactured according to this embodiment is more compact than the machine described in the previous paragraph.
• the material portion from the front end of the hose portion can be torn off. This is only possible in the first-mentioned embodiment, when the bottom is formed at the trailing end of the hose section, which is, however, apart from the rule due to the relatively complicated procedure.
• a device for removing material sections is provided in the additional tear-off.
• This device may include suction devices, pliers or a combination of suckers and pliers.
• the device for removing material sections comprises at least one needle roller.
• the said device for removing material sections can simply consist of needles which are associated with one of the rollers of the Abr disclosewalzencrues, so that no additional needle roller is required. These needles may be disposed within the roller and slidably mounted relative to this roller.
• the first separating device for separating individual tube sections which is also referred to as a first tear-off device in this patent application, comprises holding means with which or which the material section to be torn off later is fixed. Such holding means are moved so that the material portion is at rest relative to the piece of tubing to which this portion of material belongs.
• the retaining means must move with the circumferential speed of the rollers of the roller pair, which accelerates the hose section to be torn off.
• the retaining means must move at the transport speed of the hose.
• holding means are preferably the peripheral surfaces of other rolls in question.
• additional holding means when the Abr thoroughlywalzencru or Vorzugswalzencru detect the abstressed tube section or the following hose directly in the region of said material section.
• any circulating transport means are conceivable, such as conveyor belts, which are guided over several rollers or rollers and ultimately fulfill the same purpose as the aforementioned rollers.
