The action pattern of the amount of web feeding by the lug folding flaps is made optimal in accordance with deviations of detection marks, such as specified printing patterns on the printing surface on web W, from the reference values when they are detected, and the pressing force applied onto web W by dancer roller 9 is stepwise or continuously adjusted according to the detection of the patterns. Therefore, in comparison with the conventional examples, it is possible to widen the corrective range for the amount of web feeding. Thus, the tolerance for printing errors on web W can be increased, and it is possible to operate the equipment without stopping. Furthermore, it is possible to produce packaging containers with printing patterns applied at appointed positions, and faulty products are eliminated.

The invention is to provide a method and a device, etc. for molding tubes, free from any fear of the web being broken, which do not generate any wrinkle on a web when molding a plate-like web to rectangular parallelpiped packaging containers via a tubular web. In a tube molding method of the invention for molding a plate-like web to a tubular web while transferring the former along the roller surface formed by a plurality of rollers 11 through 13 of the molding roller 4, a roller supporting plate 16 is turned by a tightening member 29 while being position-regulated by a roller 25 attached to the roller attaching arm 23 so that web is transferred on the basis of the hypothetical center axis line (Point X) of the tubular web, which is formed by the roller surface constituted by the rollers 11 through 13, wherein the web in the lengthwise direction can be accurately transferred so that the same web takes a predetermined orientation of the rollers 11 through 13. As a result, it is possible to produce a high molding accuracy, for which the creasing lines of web in the lengthwise direction are made coincident with ridges of square-post-like web in its lengthwise direction when molding the square-post-like web from the tubular web.

Featured is a web sealing device for controlling the sealing pressure so as to carry out a sufficient sealing while monitoring the sealing pressure directly acting on the web. Also featured is a packaging container producing equipment using the aforementioned sealing device and a packaging container producing method using the same. When sealing a part of web W by engaging hooks 16a, 16b, which directly give a sealing pressure to the web W in order to seal a part of both web N by heating and melting both side surfaces of a double web while pressing the same, the strain amount of the hooks 16a, 16b is measured by a strain gauge 23. and the aforementioned sealing pressure is controlled by the controller 21 so that the waveform of the data, in which the values obtained by converting the aforementioned measured strain amount to pressure are continuously recorded in line with the elapse of time, becomes nearly identical to that of the master data, reflecting on the compressing time by the hooks 16a, 16b, compression timing, and the pressing force of the cylinder 18 for actuation of the hooks, and the adjustment of the drive amount of the drive device for the cross sealing of a pair of sealing jaws 7a, 7b.
