The invention relates to a method for forming at least one bottom on a hose piece (20), which comprises plastic material, wherein at least one end of the hose piece is pulled open along at least one first folding edge (21), a bottom rectangle (22) and triangular pockets (23) thus being formed; wherein side tabs (25, 26) of the bottom rectangle are folded back along two folding edges (24) spaced apart from the first folding edge in order to close the bottom, wherein the two side tabs then contact each other, and wherein a bottom cover sheet (31) is applied to the bottom and is connected to the side tabs and at least one triangular pocket by application of heat or by means of glue. The surfaces of the side tabs that come into contact and the triangular pockets are connected to each other at least in the region of the two folding edges, a connection (32) thus being formed.

Methods and devices for bonding a plurality of substrates in a nip provided between an anvil and a bonding device may involve preheating a portion of a first substrate for a preheating duration to impart a preheated temperature, and then conveying the plurality of substrates to the nip to form a bond. The portion of the first substrate may reach the nip at a final temperature that is within 0 C. to 40 C. of the preheated temperature. A time-in-nip to create the bond may be less than 20 milliseconds. The preheating duration may be at least 200% longer than the time-in-nip. Laminate materials formed via such methods and devices may include unbonded areas in the nonwoven material that may have at least 5 fibers per square inch that are fused at fiber-to-fiber intersections caused by preheating the nonwoven material.

A heating-nozzle arrangement for heating a partly formed packaging container, comprises one or more nozzle assemblies, arranged to direct a heated air flow to portions of a packaging container to be sealed; a gas-supply portion, arranged to supply a mass flow of heated gas to the nozzle assembly, further the nozzle assembly comprises at least a first and a second hole pattern and that the heating-nozzle arrangement further comprises a selector for directing the mass flow of heated air towards the first hole pattern or the second hole pattern respectively.

A heating tool for preparing a planar material for cutting, the heating tool includes an airflow generator for generating an airflow; a heater for heating the generated airflow; a flow director assembly configured to direct the heated airflow, wherein the flow director assembly is configured to move between a first configuration and a second configuration, wherein in the first configuration, the flow director assembly directs the heated airflow towards a heating target position and, in the second configuration, the flow director assembly directs the heated airflow away from the heating target position; and means for powering motion of the flow director assembly between the first configuration and the second configuration.

Welding rod for performing a plastic weld on plastic panels, so as to fasten them to one another, and related methods. Use of welding rods, or structural and welding profiles, having at least one tongue below which is a boss extending longitudinally and forming a material reserve. Once the welding rod is placed along a desired weld line, under the effect of heating, the material reserve is softened and fuses with a panel portion situated opposite it, so as to produce a final plastic weld, and the tongue is folded down on said weld line, to conceal it.

A machine for welding an overlapped region of two adjacent strips of material and a method of using the same. The machine includes a housing with front and rear ends, a wheel train engaged with the housing for moving the housing across the material; a nozzle on the housing having a welding head at a free end; the nozzle being positionable at least partially beneath the housing's bottom wall for welding the overlapped region; front and rear pressure rollers engaged with the housing, where the front roller is positioned forwardly of the welding head and the rear roller is positioned rearwardly of the welding head; wherein the rear pressure roller applies pressure to the overlapped region when the wheel train moves the housing in a forward direction; and the front pressure roller applies pressure to the overlapped region when the wheel train moves the housing in a reverse direction.

The present invention is related to a method of bonding tarpaulin and tarpaulin manufactured thereby. More specifically, the present invention is characterized in that the engaging area formed by overlapping the first and second tarpaulin fabrics each other is weld-bonded by means of hot air blowing from the first L-shaped nozzle, and the tarpaulin band is weld-bonded along the upper part of said weld-bonded engaging area by means of hot air blowing from the second L-shaped nozzles, wherein said tarpaulin band is melted in its underside by means of hot air from the second L-shaped nozzles and is weld-bonded to the first and second tarpaulin fabrics to entirely cover the engaging area with a sufficient establishment of a widthwise size. Thus, a better strength is provided in the engaging area and the tarpaulin fabric is improved in its robustness, durability and marketability.

A method and device for thermal activation of tube-shaped packaging sleeves made of cardboard/plastic composite material, wherein a hot gas is applied to the tube-shaped packaging sleeve by a heating device in order to produce the base or the head of the packaging. To achieve even heating for the activation of the contact surfaces with production using simple construction, wherein the energy required for the activation process is used as completely as possible for the heating of the surfaces to be activated, the heating device is placed into effective contact with the surfaces to be activated by the heating device being moved inside the tube-shaped packaging sleeves for activation. The heating device has at least one nozzle element with an outlet opening, the external shape of which nozzle element corresponds to the internal shape of the end of the tube-shaped packaging sleeve to be activated.

The invention relates to an edge trim for pieces of furniture, comprising a meltable layer. In order to improve a generic edge trim such that the same is more versatile and can especially be mounted on a wider selection of surfaces, the molecular structure of the meltable layer contains both polar and non-polar parts.

A heating-nozzle arrangement for heating a partly formed packaging container, comprises one or more nozzle assemblies, arranged to direct a heated air flow to portions of a packaging container to be sealed; a gas-supply portion, arranged to supply a mass flow of heated gas to the nozzle assembly, further the nozzle assembly comprises at least a first and a second hole pattern and that the heating-nozzle arrangement further comprises a selector for directing the mass flow of heated air towards the first hole pattern or the second hole pattern respectively.
