Apparatus for fabricating an elastic nonwoven material
An apparatus for fabricating an elastic nonwoven material generally includes a rotary ultrasonic horn and a rotary anvil positionable in close proximity to the ultrasonic horn. The anvil has a face with a width and a circumferential axis. The face has a plurality of ridges each of which defines a plurality of interspaced lands and notches.
Meltfusion bonded absorbant structure comprising fibres and superabsorbant particles method for manufacturing such structure
The present invention is an absorbent structure comprising a fibrous matrix (110), meltfusionable material and superabsorbent polymer particles (140). The absorbent structure is bonded by a meltfusion bond point (200) pattern, which is preferably created by ultrasonic welding.
Fixing device of plurality of sheets associated with absorbent article, and fixing method
A fixing device for fixing an elastic sheet and a low-stretchable sheet via fixing parts while superposing the sheets in a thickness direction includes: a rotating member including protrusions on an outer peripheral surface to form the fixing parts and rotatable along a transport direction; and a sandwiching member arranged at a predetermined position of the rotating member in a rotational direction, and sandwiching the sheets by a surface portion in cooperation with each of the protrusions to form the fixing parts when each of the protrusions passes through the predetermined position, the surface portion being larger than a top surface of each of the protrusions. At a sandwiching position in which the sheets are sandwiched cooperatively by the sandwiching member and the rotating member, the low-stretchable sheet is located between the elastic sheet and the top surface of each of the protrusions of the rotating member.
Method of manufacturing a foil tape and foil tape
The invention relates to a foil tape (10) for sealing joints between structural elements (30, 31) which are joined to one another, for example in house-building between masonry and a door or window jamb, wherein the foil tape (10) has a functional membrane (1), a textile (4) joined, preferably all-over, to the functional membrane (1) on a top side or an underside, and at least in certain areas an adhesive layer (2) applied in certain areas to that side of the membrane (1) which is averted from the textile (4), wherein the foil tape (10) is folded to produce a folded body (20), so that sections of the textile (4) lie on top of one another at least in certain areas, the sections of the textile (4) lying on top of one another being welded to one another partially and in particular in a punctiform pattern by supplying energy to the folded body (20).
Elastic structure for absorbent sanitary products, and a method and apparatus for its production
An elastic structure for absorbent sanitary products, comprising a sleeve comprising a first layer and a second layer overlapping each other, at least one elastic thread, and a plurality of first connecting portions spaced apart in a longitudinal direction, wherein each of said first connecting portions comprises two first welds arranged on opposite sides of the thread, wherein the first welds weld said first and second layers to each other in a first longitudinal portion of said sleeve, and a plurality of second connecting portions spaced apart in the longitudinal direction, wherein each of said second connecting portions comprises at least one second weld, wherein said second welds weld said first and second layers to each other in a second longitudinal portion of said sleeve without axially connecting the thread to said second longitudinal portion of the sleeve.
Method and Apparatus For Making Bag Using Ultrasonic Sealing
A method and apparatus for making bags or pouches is disclosed. An ultrasonic sealer may be used to form the seals. Sealing patterns may be used to provide a desired strength profile.
METHOD AND DEVICE FOR PRODUCING A FIBER-REINFORCED SEMI-FINISHED PLATE BY ULTRASONIC WELDING
The present invention provides a continuous method for producing a fiber-reinforced semi-finished plate. The present invention also provides a device for carrying out the continuous method for producing a fiber-reinforced semi-finished plate. The present invention provides the fiber-reinforced semi-finished plate.
HIGH ALTITUDE BALLOON AND METHOD AND APPARATUS FOR ITS MANUFACTURE
A high altitude balloon, including a method and machine for manufacture, uses a perimeter border strip to couple two circular balloon panels with a lap or butt seal. Simultaneous sealing of two perimeter seals, one between the border strip and each of two balloon panels, is provided by supporting stacked balloon panels on a rotatable support and sealing around the full perimeter of the two interposed balloon panels and the border strip. The method and machine for manufacture allow for the mass production of high altitude balloons and minimize necessary material handling. The perimeter border strip can be dispensed and guided relative to the perimeter of the balloon panels for positioning before sealing together, as a bonding device is rotated relative to the balloon envelope.
Device for Processing, in Particular for Ultrasound Welding, of Packaging Sleeves
A device for processing, in particular for ultrasound welding, of packaging sleeves and/or packagings includes at least two tools for processing, in particular for ultrasound welding, of packaging sleeves. Each tool has an operating region. The tools are supported in such a manner that there is produced between the operating regions a gap whose longitudinal direction corresponds to the transport direction of the packaging sleeves, and the tools are supported in such a manner that the size of the gap can be changed. In order also to enable continuous welding of the packaging sleeves in a reliable manner with changing material thicknesses, there is provided at least one parallel spring on which at least one of the tools is movably supported transversely relative to the transport direction of the packaging sleeves.
Compliant anvil
An anvil roll is configured to operatively engage with a tooling agent. The anvil includes an outer surface, an opposing surface opposite the outer surface and an inner surface. One or more spring elements are disposed between the opposing surface and the inner surface. The springs provide a compliance to the anvil.
