Abstract: A manufacturing machine for producing disposable cartridges for electronic cigarettes can have a manufacturing drum supporting at least one group of seats, each adapted to receive a component of the disposable cartridge; and a feeding unit which feeds the components of the disposable cartridges to the seats. Each seat has a housing through channel crossing the manufacturing drum from side-to-side to contain a component and a pair of opposite jaws mounted in the housing channel and movable between a gripping position, in which they engage a component arranged in the housing channel and a transfer position, in which they do not engage the component. Each pair of jaws has two teeth arranged at the top and projecting from the corresponding jaws towards the center of the seat, so that the two teeth hold the component inside the seat at the top when the two jaws are in the gripping position.

Abstract: A filter sheet media (1) for air/gas filtering applications fulfilling the criteria of standard EN779:2012 class M6 filter media, the filter sheet media (1) comprises: a first group of glass fibers (20) having a fiber diameter in a range of greater or equal to 6 ?m up to 20 ?m; a second group of glass fibers (30) having a fiber diameter in a range of 0.2 ?m to less than 6 ?m; a binder (40); the second group of glass fibers (30) have a fiber distribution gradient over the thickness (13) of the filter sheet media (1) so that the second group of glass fibers (30) are distributed through the thickness (13) of the filter sheet media (1), the filter sheet media (1) having more second group of glass fibers (30) near the first surface (11) than the second surface (12). Also disclosed is a method for manufacturing.

Abstract: Disclosed is a method of producing a non-woven web of fibrous or particulate material comprising: formation of a foam slurry; deposition of that slurry onto a foraminous element having a three-dimensional mold; and formation of a web having a three-dimensional shape that is not substantially planar by removal of foam from the slurry through the foraminous element and drying the web. An apparatus therefor is also disclosed. The method may be used in production a variety of products, including automotive pleated fluid and air filters, pleated heating and/or air conditioning (HVAC) filters, shaped breathing mask filters and bacterial filters, laminated cleaning products with super-absorbent middle layers, such as a mop wipe shape to fit a cleaning mop head, and other products.

Abstract: A non-woven web of fibrous material containing a reactive particulate material is made using the wet laid, or preferably foam, process. First and second fibrous webs are made using the wet laid or foam process, and a liquid or foam slurry including reactive particulate material is provided between the webs so as to provide a composite web. Liquid, or foam and liquid, are withdrawn from the composite web and then the composite web is dried so as to produce a final non-woven web with reactive material having substantially optimum reactivity (that is the reactive material loses a minimum amount reactivity during the web production process). The webs and slurry may be made using substantially pure water, and the particulate part of the reactive material is mixed with the foam or liquid slurry no more than about ten seconds before the liquid and/or foam are withdrawn from the composite web.
