Definitions

• the invention relates to a method for producing a pillow, a blanket or the like, according to the preamble of claim 1, a filling cartridge suitable for carrying out the method, a method for producing the filling cartridge and a cover suitable for carrying out the method.
• Cushions, blankets, or the like have hitherto been produced by filling a cover with a certain amount of filling material at the producer or dealer and then closing the cover before the finished article is handed over to the retailer or to the end customer. At least the end customer always receives a completely filled object, such as a pillow, e.g. Pillows, a blanket, e.g. a duvet or the like.
• the essentially closed casings often have an opening which can be opened and closed again.
• a filling machine from Lorch is used, with which a weighed amount of filling material is blown into the cushion cover after it has been cleaned, if necessary.
• a filling machine from Lorch is used, with which a weighed amount of filling material is blown into the cushion cover after it has been cleaned, if necessary.
• part of the filling material often gets caught in the filling machine and its individual organs. This filler must be refilled by hand.
• the filling material filled is usually lumpy. Therefore, the filling material in the filled pillow or blanket must be loosened.
• the finished pillows, blankets or the like have a
• EHSAJZBL ⁇ T RULE 26 relatively large volume, because in addition to the filling material, there is also a lot of air.
• Pillows packaged in this way are difficult to sell and their contents have to be loosened before use.
• the cover is also crumpled when the pillow is pressed together.
• the end customer Since the pillow cases are usually already filled with the filling on the manufacturing side, the end customer is dependent on acquiring pillows with a specified filling level. Filling one and the same size of a pillow with different filling levels significantly increases the storage at the producer and at the trade.
• the invention is based on the object, in particular of giving the end customer the possibility of producing a pillow, blanket or the like according to his wishes.
• the transport volume of the object should be reduced as much as possible.
• the essential consideration is to provide the filling separately from the casing.
• the filling is compressed for the purpose of transportation. The end user can thus combine a casing with a specific filling quantity according to his ideas.
• the filling By packing the filling in a filling cartridge and the existing compression of the filling, the filling expands almost explosively when the filling cartridge in the cover is opened correctly, and the individual aggregates of the filling are distributed evenly in the cover. They take in
• the envelope After the filling has been filled into the envelope, the latter is closed, for which purpose the envelope e.g. can have a zipper.
• the aggregates are under a much greater pressure in the filling cartridge than in the casing into which they are filled. As a result, after the filling cartridge has been opened due to the high pressure in the filling cartridge, the aggregates can, at least in part, fill themselves expanding into the cushion cover.
• the filled cover in particular the filled cushion, is shaken or tapped after the cover opening has been closed, in particular while distributing the aggregates in the cover.
• fiber aggregates of fibers arranged spatially to one another are used as aggregates, which are preferably spherically or tangledly interwoven.
• Feathers, down, foam sticks and mixtures of some or all four types of aggregates can also be used.
• the fiber aggregates can be sucked out of the sack in a similar way to down and blown into pillows.
• this has nothing to do with the present invention, since, according to the invention, the fiber aggregates provided for a specific casing are present in compressed form in a filling material cartridge and the user of the padded object, such as a cushion, blanket, cushion or the like, all aggregates
• SPARE BLADE RULE 26 to fill a package into a casing by opening the filling cartridge into the casing while the units are being sucked off by the known transport method.
• a filling cartridge suitable for carrying out the method for filling a casing with aggregates, in particular fiber aggregates, which is filled with the aggregates has a volume which corresponds to one third to a thirtieth of the volume of the loose, non-enveloped or packaged fiber aggregates .
• the filling cartridge preferably has a volume which corresponds to one fifth to one twentieth of the loose, uncovered aggregates.
• the filling cartridge filled with the units has a volume which corresponds to half to a twentieth of the volume of the casing.
• the filling cartridge consists of a tube which is closed at both of its longitudinal ends and which can be pushed at least with one end, but if possible completely into the opened casing.
• the hose forming the filling cartridge can be made of plastic.
• the product cartridge expediently has a predetermined breaking point which, after being slightly opened by the pressure of the units, opens further itself and permits the units to expand. If the hose is then e.g. by means of a knife slitting from one end thereof towards the other end, and thus also towards the opening of the cover of the cushion, blanket or the like, the filling material expands out of the filling material cartridge into the covering .
• the filling cartridge has an elongated shape, preferably the shape of a circular cylinder.
• an elongated plastic bag that is open at one longitudinal end can be filled with the filling with strong compression thereof and can be closed after this longitudinal end has been filled.
• a cover suitable for carrying out the method such as a cushion cover, cover cover, or the like, preferably has a closable opening, in particular a zipper, which the user of the cushion, after having filled it by means of the fiber aggregates expanded from the filling material cartridge,
• the weighed amount of aggregates is poured loosely and loosely into a measuring cylinder, the aggregates should not agglomerate when introduced.
• a flat plate with an outer diameter that is slightly smaller than the inner diameter of the measuring cylinder is placed on the filled aggregates.
• the mass of the plate is such that it exerts a pressure of 0.1 cN / cm 2 on the column of aggregates. It should also be ensured that the volume of the filling is dimensioned in relation to the geometry of the measuring cylinder in such a way that the height of the loaded column of units is at least one third of the inside diameter of the measuring cylinder.
• the filling level of the aggregates is determined, which results in the filled volume of the aggregates.
• the quotient of the weight of the aggregates and the volume of the aggregates gives the density of the loose aggregates.
• the cover is filled to the brim with small styrofoam balls, whereupon the volume of this amount of styrofoam balls is measured in a measuring cylinder.
• Polystyrene balls with a diameter between 2 mm and 4 mm are used for the measurement.
• the same procedure is used to determine the density of the aggregates in the filling cartridge; here too, the volume of the filling cartridge is determined by means of polystyrene balls, whereby an equal amount of aggregates, i.e. an equal weight is assumed.
• the ratio of the three different volumes indicates the ratio of the three different densities and - inversely proportional to this - the compression factor.
• fiber aggregates with a total weight of 450 g are filled into a pillow, the shell of which has the external dimensions 50 cm * 70 cm. In the loose state, these fiber aggregates have a density of about 12 g / l, ie they have a volume of 37.5 l. If this amount of 450 g fiber aggregates is pressed into a filling cartridge with a compression ratio of 1:20, then the volume is reduced from 37.5 1 to approx. 1.9 1. The density in the filling cartridge is then 240 g / 1.
• the fiber aggregates in the casing can relax again and fill the envelope completely.
• the density is e.g. 18 g / 1, so there is a compression factor of 1: 1.5 compared to the loose fiber aggregates.
• Such a pillow is much firmer than the pillow described above.
• an elongated plastic tube which is open at one end, is pushed over one end of a filling tube.
• the outside diameter of this tube corresponds approximately to the diameter of the tube, so that the tube sits tightly on the tube.
• units e.g. Filled in fiber aggregates and the aggregates are pressed into the tube by means of a punch inserted into the tube. This slides against a resistance acting on its free end from the filling tube until the end of the plunger pressing on the aggregates has been pressed out of the tube. Then the previously open end of the hose is closed, which e.g. can be done by means of a band or by welding the hose. The possibly protruding end of the hose is removed.
• a filling cartridge with a minimum filling quantity required for this sleeve size can be arranged inside the sleeve at its end facing away from the opening, the rest of the sleeve being wrapped around the already filled-in cartridge. This protects the cartridge better during transport.
• the filling cartridge can be made of different thickness plastic film material.
• the film material used can have a thickness of 20 ⁇ m. Since the pressure in the cartridge is much greater with a larger compression ratio, the film material must then also be thicker. With a compression ratio of 1:10, the thickness is then about 80 ⁇ m. The thickness of course also depends on the type of film material.
