A sheet manufacturing apparatus includes a defibrating unit configures to defibrate a raw material containing fiber into a defibrated material; a screening unit configured to screen the defibrated material that is defibrated by the defibrating unit; a web forming unit configured to form a web on which the defibrated material screened by the screening unit is deposited; a rotary body that includes a protrusion unit for forming a subdivided body by dividing the web formed by the web forming unit; a deposition unit configures to deposit the defibrated material configuring the subdivided body; and a forming unit configured to form the sheet by pressurizing and heating the defibrated material deposited by the deposition unit.

Disclosed herein is a solid phase matrix comprising a layer of lignocellulosic fibers that can be used as effective cargo delivery for crop protection. Also disclosed is a mechanized planter for wrapping or encasing a plant seed, seed piece, seedling, or slip into the disclosed solid phase matrix. Also disclosed is a method for protecting a plant or plant that involves wrapping or encasing the plant or plant part in the disclosed solid phase matrix.

A storage portion includes a case which includes an internal space configured to accommodate raw material pieces having fibers, a discharge pipe coupled to a side wall of the case, and a transport motor which rotates the discharge pipe on an axis, in which one end in an axial direction of the discharge pipe communicates with the internal space and the other end has an outlet for discharging the raw material pieces, and a spiral member is provided on an inner peripheral surface of the discharge pipe.

A process for producing a flaked cellulose-based thermal- and/or acoustic-insulating material includes preparing a cellulose-based pulp and providing a web of paper having a given thickness, starting from the pulp. A coating having a mixture containing a first substance having a flame-retardant function and a second substance having an anti-mould function is applied on the web. The coated web is subjected to a milling operation so as to provide flakes of flaked insulating material.

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 sheet manufacturing apparatus includes an impeller mill, a first sieve, a first belt, a rotary body, a second sieve, a second belt, and a heating roller. The impeller mill defibrates a raw material containing fiber and discharges a defibrated material. The first sieve screens the defibrated material by causing the defibrated material to pass through a first net. The defibrated material passing through the first sieve is deposited on the first belt to form a web. The rotary body has a protrusion radially protruded from a rotation center and divides the web by rotation to form a subdivided body. The second sieve refines the subdivided body by causing the subdivided body to pass through the second net to form a web. The refined subdivided body is deposited on the second belt to form a web. The heating roller heats the web from the second belt to form a sheet.
