Abstract: A tube of plastic material is cut at a bag length interval from a free end to define an open mouth. The free end is sealed to form a bag and a reclosable fastener strip is affixed to the open mouth after the tube is cut. Prior to affixing the reclosable fastener strip, but after the tube section is cut, the bag is moved away from the remainder of the tube. The side edges of the bag adjacent to the open mouth are slit and the slits and reclosable fastener strip are joined after the reclosable fastener strip is positioned in the slits. The bag may be filled after the free end of the tube is sealed but before cutting the bag length interval from the tube.

Abstract: 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.

Abstract: Bags containing a particle, powder or granule product are packed inside a wrapper formed from an elongated laminar wrapping of thermo-bonding plastic. The wrapping is sealed along longitudinal seams to form a sleeve. The bags of product are advanced on a transporter and pressed to a compact and even shape. A first bag is placed on a temporary support and the wrapping formed into a sleeve about the bag. The first bag is allowed to fall into the sleeve. The sleeve and bag are caused to ascend at the same time, and the sleeve is closed with seams during its descent. The process is then repeated for successive bags until the sleeve contains a set number of bags. The sleeve is then closed into a welded wrapping about the bags.
