A method for packaging products, wherein packaging material web is transported in direction of an upwardly open pair of folding claws, is cut to length while forming a planar blank of the wrapper, and the blank is positioned above the folding claws, wherein the product is metered, the product portion is pre-shaped, and the blank by placing thereon the pre-shaped product portion is folded into the claws while forming the upwardly open wrapper. Thereafter, the upward-projecting lateral longitudinal peripheries of the wrapper are folded inward onto the product portion, whereupon the transverse peripheries of the wrapper which extend perpendicular thereto are folded inward onto the product portion. The lateral longitudinal peripheries and transverse peripheries of the wrapper are folded inward onto the product portion and are simultaneously connected to one another, while the wrapper provided with the product portion is still situated in the pair of folding claws.

The invention proposes a method by means of which portioned products which are pasty in the processing state are packaged in a wrapper which has been cut to length from a packaging-material web, wherein the packaging-material web is transported in the direction of an upwardly open pair of folding claws and is cut to length to form a planar blank of the wrapper, and the blank is positioned above the pair of folding claws, wherein the product is metered, the product portion is preformed and the blank is folded into the pair of folding claws by virtue of the preformed product portion being placed in position, the upwardly open wrapper being formed in the process. The upwardly projecting, lateral longitudinal peripheries of the wrapper are then folded over inwards onto the preformed product portion, whereupon the transverse peripheries of the wrapper, which extend perpendicularly to the longitudinal peripheries thereof, are folded over inwards onto the preformed product portion. The invention makes provision for at least the lateral longitudinal peripheries, preferably also the transverse peripheries, of the wrapper to be folded over inwards onto the preformed product portion, and connected to one another at the same time, while the wrapper provided with the preformed product portion is still located in the pair of folding claws. The invention also relates to a packaging machine which is suitable for implementing such a method.

B65B 29/00 - Packaging of materials presenting special problems
A method for the portioned packaging of liquid or pasty products using a packaging machine. The product is fed via an inlet to a metering chamber, being metered in the metering chamber by a metering member to form a product portion, and the product portion being fed via a metering outlet to a package. In order to avoid impairments of products which are sensitive to crystallizing out in the inoperative state, the metering chamber is operated in continuous flow in at least one operating state of the packaging machine from the following group: downtimes of the packaging machine, start-up of the packaging machine and operation of the packaging machine, by the product—whether entirely or in a partial flow—being removed entirely or partially from the metering chamber past the metering member via an outlet provided in addition to the metering outlet and being recirculated.

METHOD FOR PACKAGING LIQUID OR PASTY PRODUCTS AND PACKAGING MACHINE SUITABLE FOR THIS PURPOSE
The invention relates to a method for the portioned packaging of liquid or pasty products by means of a packaging machine, in which the product is fed to a metering chamber via an inlet, then metered to a product portion in the metering chamber by means of a metering element, the product portion being subsequently transferred into a package via a metering outlet. In order to avoid damage to the products which are susceptible to from damages, which are sensitive to crystallization in the rest state, the invention proposes that the metering chamber is operated in continuous flow in at least one operating state of the packaging machine among the downtimes of the packaging machine, the start-up of the packaging machine and the operation of the packaging machine, in which the product is discharged - either entirely or partially - from the metering chamber and is recirculated via an outlet provided in addition to the metering outlet, thereby passing the metering element. The invention further relates to a packaging machine suitable for carrying out such a method.

METHOD FOR PACKAGING LIQUID OR PASTY PRODUCTS AND PACKAGING MACHINE SUITABLE FOR THIS PURPOSE
A method for portioned packaging of liquid or pasty products, and a packaging machine therefor are provided. The product is fed to a metering chamber and metered by a metering member to form a product portion. The product portion is fed via a metering outlet to a package. The metering chamber is operated in continuous flow in at least one operating state of a packaging machine including downtimes, start-up and/or operation of the packaging machine. The method comprises feeding the product into an inlet, thereby causing the product to flow through the metering chamber in an axial direction; guiding the product past the metering member through an annular gap between the metering member and an inner circumferential wall of the metering chamber, wherein the product flushes around the metering member; removing the product entirely or partially from the metering chamber via an outlet; recirculating the product.

Method and device for packaging product portions in a wrapper
A method and a device for packaging product portions in a wrapper are proposed, wherein at least two webs of a packaging material are aligned parallel, with the longitudinal edges facing each other overlapping, and each transported towards one upwardly open folding shaft, the webs are severed transverse to the overlapping longitudinal edges, creating flat blanks of the wrappers, and the blanks are folded into the folding shaft , creating an upwardly open wrapper, whereupon the product portion is placed in the open wrappers and the upwardly protruding sections of the wrappers are then turned inward while overlapping. The blanks, whose inner edges overlap, are guided in frictional engagement to their folding position above the folding shafts, whereupon the longitudinal edges of the overlapping blanks facing each other are, lifted together , whereupon the blanks are released by releasing the frictional engagement.
