Embodiment Construction

[0050] figure 1 A schematic perspective view of a filling system 100 is shown comprising a dispensing silo 104 and a high velocity stream 101 and a low velocity stream 102 for filling bulk material, especially powdered food, into open-mouth bags.

[0051] The filling system 100 includes a bag making device 1 . The bag-making plant 1 is installed upstream of the filling and produces a film roll or a film tube roll 21 on which the bag film 5 is wound into individual open-mouth bags 2 (see Figure 4 ), which is filled with the desired filling bulk material via the filling nozzle 110 of the filling system 100 after being towed by means of the towing device 26 .

[0052] The filling system includes a rotary filling nozzle 110 that advances to each station in rotation. After being towed to the first filling nozzle, the next station performs high-velocity flow filling, and then proceeds further for low-velocity flow filling. Both the high-speed flow filling station and the low-spe...

Abstract

Plant and method for the manufacture of open-mouth bags (2), comprising a storage device (3) with a stock (4) of bag film (5), a control device (60) for control, for conveying the bag film ( 5) and / or the transfer device (6) of the bag body (16), the welding device (8) with the welding mechanism (9, 10) for adding the bottom seam (11) in the bag film and the welding device (8) with the A predetermined film length (15) of the bag film (5) is used to form the cutting device (12) of the cutting mechanism (13, 14) of the bag body (16) of the open-mouth bag (2). The control device (60) controls the conveying device (6) to cause the relative movement of the bag body (16) and the bag film (5), between the bag body (16) and the bag film (5) before adding the bottom seam (11). A distance (37) is generated between them. The control device (60) controls the transfer device (6) and the welding mechanism (9, 10) so that the welding mechanism (9, 10) extends at least as far as the bottom end (23) of the bag (16) when the bottom seam (11) is welded. ).

Description

technical field [0001] The present invention relates to a bag-making apparatus and method for making open-mouth bags and to the open-mouth bags thus produced. Such bag making plants are used in particular with or for FFS systems (Form-Fill-Seal) to manufacture on-site open-mouth bags into which bulk material needs to be filled. It is also possible to utilize the bag making equipment of the present invention to produce reserve bags and temporarily store them for later use. Background technique [0002] In particular, food products can be filled into manufactured open-mouth bags. Especially preferably, powdered food products such as milk powder, glucose, starch, etc. are filled into open-mouth bags. The packaging of food products, especially baby food, requires a high level of hygienic standards. Bags filled with food should have as few dirt particles attached as possible. [0003] For the manufacture of open-mouth bags, the tendency is to use tubular films conveyed in one...
