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: This invention relates to a process for the continuous production of beverage filter bags, especially tea bags with a hanging strip made from a carrier sheet material and with at least one pocket which consists of a filter material and is closed on all sides, contains at least one portion of a beverage substance, and is connected to the hanging strip; whereby individual beverage-substance portions are deposited in a row on a continuous web of filter paper, a sleeve is formed, at least one string of consecutive, contiguous pockets, each containing one portion of the substance, is produced by individually sealing them off with a transverse seam, said transverse seam including both the trailing seam of one pocket and the leading seam of the following pocket, with perforations between the two seams along which neighboring pockets can be separated in the course of the process; the individual pocket is separated from the string of pockets; the pocket separated from the string of pockets is connected to a hanging-st

Abstract: This invention concerns a method and a device for stacking and packing groups of infusion bags, especially for making tea, whereby in continuous production infusion bags arranged one after another in a series in a strand are separated, their speed of movement is reduced and they are put in a position suitable for making a stack, whereby the infusion bags are arranged one after another in such a way that they at least partly overlap in their subsequent direction of movement.

Abstract: This invention concerns a device for transporting a strand of carrier material which is connected, at least on one side, to individual chambers made of filter paper material, spaced apart, following one after another, closed on all sides, containing a quantity of substance and composed of a strip of carrier material, with at least two independently driven belts, one segment of which runs at least partly parallel to the strand of carrier material and having cams spaced apart on the side facing the strand of carrier material, whereby they grasp the strand of carrier material between the chambers and/or in the area where one chamber is connected to the strand of carrier material, working along with a support, and transport it with the movement of the belts.

Abstract: This invention concerns a method and a device for stacking and packing groups of infusion bags (1), especially for making tea, whereby in continuous production infusion bags (1) arranged one after another in a series in a strand (2) are separated, their speed of movement is reduced and they are put in a position suitable for making a stack, whereby the infusion bags (1) are arranged one after another in such a way that they at least partly overlap in their subsequent direction of movement.

Abstract: This invention concerns a device for transporting a strand (12) of carrier material which is connected, at least on one side, to individual chambers (6) made of filter paper material, spaced apart, following one after another, closed on all sides, containing a quantity of substance and composed of a strip of carrier material, with at least two independently driven belts (2, 3), one segment of which runs at least partly parallel to the strand (12) of carrier material and having cams (4, 5) spaced apart on the side facing the strand (12) of carrier material, whereby they grasp the strand (12) of carrier material between the chambers (6) and/or in the area where one chamber (6) is connected to the strand (12) of carrier material, working along with a support, and transport it with the movement of the belts.

Abstract: This invention relates to a system for the continuous separation of strings of material, subdivided into individual string subsections or pockets by transverse perforations, especially in the context of the production of tea filter bags, incorporating a continuously rotating wheel (1) and, beside the wheel (1), grippers (3) which are tiltable relative to the wheel (1) and serve to grasp the longitudinal sides of a string subsection to be separated from the string at a predefined point near the perforation, said string subsection permitting separation by means of the relative movement between the grippers (3) and the wheel (1).
