A crushing mill for crushing fibrous material for a unit for forming absorbent cores in a machine which makes absorbent sanitary articles, including a casing having an infeed opening and an outfeed opening for the fibrous material, a rotor rotatable about its axis of rotation and housed in the casing at an intermediate position between the infeed opening and the outfeed opening. Also provided is an auxiliary opening operatively interposed between the infeed opening and the outfeed opening, with reference to a direction of rotation of the rotor, and adapted to allow feeding a particulate absorbent material into an intermediate zone between the infeed opening and the outfeed opening.

A corner trim material that is made of a material that will bond with current industry mastics such as all purpose joint compounds, resists impact, resists abrasion, and readily accepts common coatings such as drywall mud, texture and paints. The surface of this material generally does not need to be covered by any secondary fiber based material such as paper to improve bonding or coating on the inside or outside. The material generally consists of a polymer mixed with a fibrous material like pulp or glass fiber. A corner trim piece can be directly extruded from the mix. The corner trim piece can have a center hinge, can be bullnose, and the flanges can optionally have holes or optionally be coated with adhesive.

A product capable of controlling odours arising from organic matter, and a method of making the product. The product comprises an admixture of a moldable thermoplastic and a benign dormant bacteria in a sporulated form, which admixture is formed by mixing the benign dormant bacteria into the moldable thermoplastic when the moldable thermoplastic is melted, and molding the admixture into a molded product. The benign dormant bacteria are embedded throughout the molded product, including being buried within a body of the molded product and being presented on a surface of the molded product. The benign dormant bacteria presented on the surface of the molded product are activatable upon exposure of the surface of the molded product to the organic matter, and the benign activated bacteria digest the organic matter to control production of offensive odours. Abrasive wear of the surface of the molded product exposes fresh benign dormant bacteria buried in the body to the surface for additional odour control.

An extruder is disclosed, and more particularly, to an integrated single screw extruder and a twin screw extruder for mixing, compounding, kneading and/or extruding of materials. The integrated extruder includes a first barrel assembly and a second barrel assembly. The integrated extruder further includes a first screw having a first threaded portion and a second threaded portion. The first threaded portion is housed within the first barrel assembly and is configured to provide upstream material processing. The second threaded portion is housed within the second barrel assembly and is configured to provide downstream material processing. The integrated extruder further includes a second screw having a non-threaded shaft portion and a threaded portion. The threaded portion of the second screw is housed within the second barrel assembly and is configured to provide the downstream material processing with the second threaded portion of the first screw.
