The present invention provides, in various embodiments, a rotary-type machine (M) for continuously sealing individual foil bags (B) by way of ultrasonic welding between an anvil (6) and a sonotrode (5) in at least one welding station (S) of a carousel (1), where each foil bag (B) can be positioned by way of holders (11). In some embodiments, the rotary-type machine (M) comprises at least one welding station (S) composed of a sonotrode (5) being located stationary at least relative to the direction of circulation (8) and anvils (6) which with intermediate spacings (7) rotate past said sonotrode (5) successively in the direction of circulation (8) of the carousel (1). According to the invention, the foil bags (B) are sealed at the stationary sonotrode (5) when the anvils (6) equipped with the foil bags (B) are rotated past.

A process for the marking of a film or a bag, which consists of a film at least in sections, wherein the film or the bag comprises a medical product or is provisioned or prepared for the uptake of such, wherein the process comprises connecting a film strip with, in, to and/or on the film, wherein the film strip carries information for marking the medical product.

The film sealing and wrapping machine with a rotary cut and seal jaw is provided. The rotary cut and seal jaw has an internal sliding mechanism which provides for smooth and quiet operation. The rotational speed of the jaw may be varied to increase through put and to provide for a title bag around products. The rotary cut and seal jaw may comprise a seal bar and pressure pad may both be spring loaded to self align the seal bar and pressure pad during the sealing and cutting process. Lastly, a gap defined by a belt disposed upstream and downstream of the seal bar and pressure pad may be mechanically linked to the pressure pad through a control carriage.

In a method for forming a lateral sealed portion, a liquid packing material can be filled without biting bubbles, granulates and so on included in the liquid packing material into the lateral sealed portion. In a method for forming a lateral sealed portion with a pair of lateral sealing rolls after a packaging film fed and run is folded at its central portion and a vertical sealing is performed at their side edge parts to shape into a cylindrical form and a liquid packing material is filled into an inside of the cylindrically formed packaging film, at least a folded side part of the cylindrically formed packaging film is pushed with a pushing means arranged between heat sealing bars located at equal intervals in a circumferential direction of the lateral sealing roll and the lateral sealed portion is formed at a pushed position with the pair of lateral sealing bars.

A method and a device are disclosed for making thin plastic films having two or more layers, which are subdivided and separated in the form of tubular bags for portioned reception of different products, wherein the plastic films are provided with welding seams running substantially transversely to the longitudinal direction with predetermined spacing between one another to form bag-like containers, and the containers are separated from one another by a cutting or separating process, the method being characterized by the steps: a) welding the films with predetermined spacing by means of an ultrasound welding process, maintaining a defined, film-dependent distance between a processing tool and a counter tool while welding; and b) separating the tubular bags welded in this way by means of a mechanical cutting process, with or without reduced ultrasound excitation at the point of the respective weld seams.

In an example embodiment, a doser assembly includes a hopper assembly configured to receive plant material, a bracket assembly connected to the hopper assembly, and a roller in a hopper opening defined by the hopper assembly extending through the hopper assembly. An interior surface of the hopper assembly may define the hopper opening. The bracket assembly may include a shaft extending across a portion of the hopper opening. The roller may be in the portion of the hopper opening of the hopper assembly and may extend between a first part and a second part of the interior surface of the hopper assembly. The roller may be connected to the shaft and may be configured to rotate with rotation of the shaft.

A container is provided with a flange defining a container opening that may help expunge food product as the film and seal head comes down on the container flange. The flange of the container opening has a predetermined angle. The container flange with its sealing surface generally deflects or angularly pivots when sealed with the film during the sealing process. The container flange and film may push product contamination from the sealing surfaces inwardly into the container. The flange may be continuous about the periphery of the container opening.

A sealing device for forming a transversal seal to a tetrahedral packaging container is provided. The sealing device comprises a sealing element and an imprint ruler arranged at a longitudinal distance from the sealing element. The sealing element is configured to provide a top transversal seal to a packaging container while the imprint ruler is configured to provide a transversal imprint to the same packaging container.

The invention relates to a device for making a sealing connection between two material layers containing plastic, especially in a product packing pouch (2), having at least one sealing station (3), comprising at least two sealing jaws (4a, 4b) situated opposite each other and movable between an open position and a sealing position, having respectively a sealing surface (5a, 5b) on their inner side facing toward the other respective sealing jaw (4b, 4a), wherein the sealing station (3) is configured such that in the open position at least two material layers (6, 7, 8) to be joined together by sealing can be arranged between the sealing jaws (4a, 4b) and in the sealing position the material layers (6, 7, 8) can be pressed together. It is proposed that at least one of the sealing jaws (4a, 4b) comprises at least one lubricant channel (9) and the device (1) comprises a lubricant delivery device (10), which is configured to direct a lubricant through the lubricant channel (9) toward the sealing surface (5a, 5b) of the sealing jaw (4a, 4b) and/or toward the sealing surface (5b, 5a) of the oppositely situated sealing jaw (4b, 4a).

A bag (100) for packaging fruit and vegetable products (2) having a casing (103) for housing the products to be packaged and at least one first band (104) and one second band (105), each arranged on the outer face of the casing so as to seal the casing, the first band (104) being joined to the casing only at its ends (104a, 104b) forming a handle (106) and the second band (105) joined along the length thereof to the associated face of the casing, forming a stable bottom (105c).
