Abstract

A method of producing a needled product of a selected material or materials of a desired thickness and size. A first carded batt of a selected material or materials is moved from a feed support into a needle loom between a vertically reciprocating needle bed and a support bed located beneath and in spaced relation to the needle bed. The needle bed and/or the support bed are vertically movable to vary the spacing therebetween. The upper surface of the first carded batt is penetrated by the needles in the needle loom so that the needles do not reach an upper surface of the support bed and are able to flex laterally. The needled first batt is then lifted and moved to the feed support or a feed support for another needle loom. Thereafter, a second batt is positioned over the first batt in overlapping relation, the needle bed or support bed is moved to increase the vertical spacing therebetween to accommodate the overlapped batts, and the batts are moved through the needle loom and connected. This method may be repeated to add additional overlapped batts to produce a layered product of any suitable thickness.

IPC Classes  ?

• D04H 1/46 - Non-woven fabrics formed wholly or mainly of staple fibres or like relatively short fibres from fleeces or layers composed of fibres without existing or potential cohesive properties the fleeces or layers being consolidated by mechanical means, e.g. by rolling by needling or like operations to cause entanglement of fibres
• D04H 3/105 - Non woven fabrics formed wholly or mainly of yarns or like filamentary material of substantial length characterised by the method of strengthening or consolidating with bonds between yarns or filaments made mechanically by needling
• D04H 18/02 - Needling machines with needles
• D04H 3/10 - Non woven fabrics formed wholly or mainly of yarns or like filamentary material of substantial length characterised by the method of strengthening or consolidating with bonds between yarns or filaments made mechanically

Abstract

A device and method for supporting a meltable tart and removing hot molten wax or other material from the tart when heated. The device has a heat resistant body formed of a material that is of sufficient porosity to absorb or soak up hot molten wax or other material from the tart and to retain its structural integrity so that it can be disposed of after it has absorbed or soaked up the hot molten wax or other material from the used tart.

IPC Classes  ?

• A61L 9/02 - Disinfection, sterilisation or deodorisation of air using gaseous or vaporous substances, e.g. ozone using substances evaporated in the air by heating or combustion
