An apparatus for use in the manufacture of an article from first and second non woven sheets comprises (a) a sealing station for producing a seal of a defined pattern (392) between the first and second sheets and (b) a cutting station for producing a cut of a defined cutting pattern to the first and second non woven sheets, the seal being produced by produced by ultrasonic sealing (393) and the seal pattern is defined by a cylindrical sealing die (390). The cutting station may be provided by a cylinder (394) provided with a raised cutting die pattern (375), which generally follows the outline of the ultrasonic seal (370) and an interacting second cylinder (395) provided with a second relief pattern (398). The article may be a glove liner comprising a first skin contacting layer comprising a non-woven material and a second layer comprising a waterproof material. The non woven material may comprise spun-bonded, melt blown or chemically bonded polypropylene, polyester or other thermoplastic fibres or blends. The waterproof material such as polypropylene or polyester may be breathable. |
