摘要:
The invention describes a machine for forming, filling and sealing (FFS) sacks (8, 11). As device characteristics, it covers an unwinding device (19) for a plastic tube (15), a cross-cutting device (17) that cuts the tube perpendicularly to its principal axis of symmetry and creates tubular pieces in the process, a bottom forming means (13) for forming a sack bottom at one end of the tubular piece, transport equipment (4, 10, 18) to transport the resulting sacks through the machine, a filling station with a feeding element (2) for filling the product (24) in the sack (8, 11), means (3, 4, 5) of reducing the distance between the product discharge opening of the feed element and the bottom of the sack to be filled as well as sealing means to seal the filled sack. In this context, the means (3, 4, 5) of reducing the distance between the product discharge opening (31) und the bottom of the sack to be filled covers a sack lifting device (3, 4, 5) with which the sack (8, 11) can be lifted in the filling station in such a way that its upper edge (25) is located above the product discharge opening (31) of the feed element (2).

A machine for forming, filling, and sealing sacks has an unwinding device for a plastic tube, a cross-cutting device that cuts the tube perpendicularly to its principal axis of symmetry and creates tubular pieces in the process, a bottom forming means for forming a sack bottom at one end of the tubular piece, transport equipment to transport the resulting sacks through the machine, a filling station with a feeding element for filling the product in the sack, means of reducing the distance between the product discharge opening of the feed element and the bottom of the sack to be filled, and sealing means to seal the filled sack. The means of reducing the distance is a sack lifting device with which the sack can be lifted in the filling station such that an upper edge of the sack is located above the product discharge opening of the feed element.

A method for the production and filling of packaging includes unwinding flattened tubular film material from a roll along a primary axis of symmetry thereof, providing the tubular film material via a welding and separating process with a first lateral welding seam perpendicular relative to the axis, and separating the tubular film material along a separation line to provide a hose section. The hose section open at one side is filled, and the still open other side of the hose section is provided with a second lateral welding seam. Two subsequent separation lines are inserted in the hose section at a distance that is less than the distance between the two edges of the hose.
摘要:
A method for the production and filling of packaging means is described and claimed, in which the following production steps are performed: flattened tubular film material is wound off a roll along the primary axis of symmetry of the hose, the tubular material is provided via a welding and separating process with a first lateral welding seam perpendicular in reference to the tubular axis and separated along a separation line, the hose sections open at one side are filled, the still open end of the hose section open at one side is provided with a second lateral welding seam. It is considered novel and inventive that two subsequent separation lines are inserted in the hose at a distance, which is smaller than the distance between the two edges of the hose.Additionally, a device is described and claimed comprising features allowing the implementation of the method.
摘要:
The invention describes a sack (220) which (220) is formed by first transverse sealing seams (110, 150) from a foil tube (101), and which (101) is provided with at least a first vent channel (20), which runs largely parallel to the axis of the film tube (101), and whose inner (40) film layer has first vent openings for venting of the sack interior (210) into the first vent channel (20). It is characteristic that at least a second vent channel (140) is provided, which is connected to the first vent channel (140) by second vent openings (90, 100, 200), and which, in turn, has third vent openings (120), which vent the at least one second vent channel (140).

The invention relates to an advancing device (10) for advancing a film web (200) in a bag filling installation (100, having a main advancing drive (20) with at least one driven main advancing roller (22) for advancing the film web (200), wherein for an adjustment of the tensile stress of the film web (200) in the transport direction (T) of the film web (200) an auxiliary advancing drive (30) is disposed before the main advancing drive (20) with at least one driven auxiliary advancing roller (32) for advancing the film web (200).
摘要:
The invention describes a system for manufacturing sacks or bags, which comprises at least two machines which control components are assigned to, which are connected with each other by at least one transport and/or one storage device. It comprises a control unit, which is equipped in such a way that the manufacturing speeds of at least two machines can be transmitted to and/or processed by it, and which is equipped in such a way that it proposes and/or sets the manufacturing speed of at least two machines based on system operating parameters.
摘要:
A device for continuous winding of webs on winding shafts onto winding rollers consisting of arms supporting the winding shaft, a pressure roller that can be engaged on the winding shaft or winding core, a knife separating the web during the roller change, and of a charging electrode supplying the web start with an electrostatic charge, which attaches the web start, newly formed by the web cut, on the winding shaft. In order to always maintain the correct equal distance to the web supplied with the charge, the same is tracked in such a manner that the distance of the charging electrode to the web remains constant regardless of the diameter of the winding shaft.

A system for manufacturing sacks or bags includes at least two sack or bag producing machines which control components are assigned to, and which are connected with each other by at least one transport device and/or one storage device. The system includes a control unit configured such that manufacturing speeds of the two sack or bag producing machines can be transmitted to and/or processed by the control unit. The control unit is configured such that it proposes and/or sets the manufacturing speed of the two sack or bag producing machines based on system operating parameters.
