Embodiment Construction

[0033] figure 1 and 2 The system of the invention is shown, comprising at least 5 stations, where each station is involved in one or more steps of the method of the invention.

[0034] refer to figure 1 , Box 1 represents the supply station, which provides the film F from the first roll B. Dotted rectangular boxes B' and B" represent alternative roll configurations. Roll B' can be placed outside and parallel to the first roll B. Preferably, roll B' has the same Width. Alternatively, Roll B" may be substituted for Roll B or B'. In this case, the roll B" is preferably N times the width of B or B'. Refer to figure 2 , and the material roll B and / or B', or B "is associated with the tension adjustment braking device DF.

[0035] figure 1 Box 2 in , represents full printing station (TP) 2a, followed by stacking station 2b. Full printing station 2a provides in-line printing of films. The accumulation station 2b deposits the printed film in line with the full printing station...

Abstract

In the system to form, fill and seal (FFS) flexible bags substantially according to Patent US-A 4,656,813 (EP-A 142.758) use is now made of: a total printing of the film as it winds off the supply reel; a dry cleaning; a gimballed aligning for the folding of the printed and washed film; a hot-bar welding of the folded film; a valve welding controlled by an algorithm; a humidification treatment ofthe valve cavity; a shaping of the bags by hot tools also controlled by an algorithm; and a high precision dosage of the filling liquid.

Description

technical field [0001] The present invention relates to a system for forming, filling, sealing (F.F.S.) containers of flexible plastic material, in particular to sterilizable packaging bags containing administration solutions for injectable solutions. Background technique [0002] A number of prior art systems are known for producing flexible containers or bags for use with injectable solutions in the medical field. For example, US Pat. No. 4,656,813 discloses a system for the industrial production of these types of bags. Packaging bags are generally referred to as form, fill, seal (F.F.S.) type containers. These bags are usually stacked and include a valve to accommodate various connectors for injectable devices, such as LUER type valves. Typically during or after the manufacturing process, the pouches are sterilized. It can be difficult to sterilize bags that include various designs such as valves. It will become more difficult to sterilize bags that currently require ...
