Abstract: A machine for forming a bag of a strip of weldable material, filling the bag with a fluent filling, and sealing the filled bag forms the strip into a longitudinally extending and laterally closed tube and continuously advances the tube longitudinally downward through a welding/folding station while pouring the filling into the tube above the station. A cross-seam welder and a folder at the station are both horizontally closable on opposite sides of the tube to form therein folds and a bag-forming crosswise weld. A vertically shiftable lifter is engageable under a filled section of the tube below the station. Simultaneously the welder and folder are closed on the tube to form a crosswise weld and to fold the tube horizontally inward while the filled section is raised and the welder and folder are moved downward generally synchronously while in contact with the downwardly moving tube.

Abstract: This invention concerns an infusion bag, especially for tea, which has a top part with folded down corners and a middle part folded over it, to which a string with two free ends is attached that goes from one side of the top part through a hole in the folded down parts forming a loop on the other side of the top part and comes back, whereby the two free ends are drawn up through the loop laid over the top edge of the infusion bag and pulled to form a knot. The solution in the invention is characterized by the fact that two holes are made in the top part at a lateral distance next to one another, on the left and right of the longitudinal axis of the bag; each hole goes through a folded down corner and the middle of the top part; by the fact that the string forms a loop and one end goes through one hole and the other end through the second hole; by the fact that the loop is laid over the top edge of the infusion bag, and both ends of the string go up through the loop to form a double knot.

Abstract: A vertical bag forming, filling and sealing machine having a feed system for a wrapping material forming the flexible tube bags, a filling tube, a longitudinal seam welding device and a cross seam welding device is described. The cross seam welding device comprises a unit forming the lower cross weld seam and a unit forming the upper cross weld seam of a flexible tube bag. The unit for generating the upper cross weld seam or a folding device and a lifting device for the filled flexible tube bag are movable up and down and are lifted for the generation of the upper cross weld seam or for the folding of the flexible tube bag in order to relax the wrapping material. By this the air space over the surface of the filling material is kept as small as possible.

Abstract: An apparatus removes textile articles such as empty tubes or full yarn packages from the individual posts on which such articles are supported simultaneous with advancing movement of the posts. The textile articles are removed in a direction generally parallel to the axis of the posts so that during removal detrimental binding of the textile article relative to the post does not occur. According to one aspect of the invention, at least one pair of endless belts are mounted in spaced, parallel relation to one another to form an elongate opening therebetween. The elongate opening is aligned with the travel path of the textile articles being advanced on the posts so that the textile articles automatically enter the elongate opening and are engaged by the endless belts without the need to stop or otherwise control the advancing movement of the textile articles.
