Abstract: A packaging container production method for forming tubular web from sheet-like web and producing hexahedral packaging containers, wherein in order to secure a prescribed web W feeding amount, the operating amount of lug folding flaps, which forms a sealing part on tubular web by pressing both sides of the tubular web while folding the same, is set an idealistic position, pressure is generated at a cylinder 16 by a control device 23 via a control valve 31, in compliance with the deviation of the detection mark such as a specified printing pattern on the printing surface on web W from the reference position when the same is detected, and the tension applied onto web W is adjusted by the dancer roller 9.

Abstract: 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.

Abstract: 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.

Abstract: A stamping device includes two stamp rollers and a support member having the two stamp rollers mounted thereon and arranged on a circumference having a center at a center of pivotal movement. The stamp rollers are spaced apart by a predetermined angle about the center, a rotary actuator for pivotally moving the support member so that one of the stamp rollers in a stamping position and the other stamp rollers in a standby position are alternately shiftable to the other position, and drive means for rotating the stamp roller in the stamping position.

Abstract: A web sterilizing device comprising a sterilizing solution tank 51, web guide means for guiding a web W so as to bring the web w into the tank 51, dip the web w in a sterilizing solution within the tank 51 and thereafter move the web W out of the tank 51, a pair of endless chains 105 extending in parallel to each other both inside and outside the tank 51, chain guide means for guiding the chains 105 so as to move the chains 105 along respective opposite sides of a path for the web W to move along by being guided through the tank 51 by the web guide means, and a web engaging member 133 extending between and connected to the chains 105.

Abstract: For use in forming a web W into a tubular shape, and heat-sealing an inner surface of outer edge of the web and an outer surface of inner edge of the web to provide a lap, a web heating device for heating the outer edge inner surface of the web with hot air before heat-sealing comprises transport means for transporting the web W along a predetermined path, a nozzle 27 having hot air outlet openings 67 directed outward as opposed to the outer edge inner surface of the web W to be transported by the transport means, and a baffle plate 32 so disposed as to be opposed to the hot air outlet openings 67 with the outer edge of the web W positioned therebetween.

Abstract: A tape joining device has a fixed bearing member 24 and a movable pressing member 46 arranged respectively at opposite sides of the portions of two tapes T to be joined, and a heater 88 for heating the pressing member 46. The pressing member 46 is attached to a movable body 44 for pressing the pressing member 46 against the bearing member 24 with the opposed tape portions positioned therebetween. The pressing member 46 is pivotally movable relative to the movable body 44 about an axis extending in parallel to the longitudinal direction of the tapes T.
