A machine, particularly for producing cellulose fiber from waste paper with characteristics and yield comparable to virgin fiber, includes at least one conveyor body which is adapted to receive the waste material from which to obtain cellulose fiber; and at least one drum which contains inside it grinders adapted to grind the waste material for the production of the cellulose fiber, and which communicates with the conveyor body.

The grinders include a grinding hammer which is arranged on the bottom of the drum and can rotate by way of a motor about a rotation axis.

The invention relates to a process for producing particle/polymer composites using a substrate S comprising shredded textile fabric products and a polymeric binder P, therewith providing a new method of recycling/upcycling textile waste. Furthermore, a process for the manufacturing of a molded article obtained from the textile-based particle/polymer composite and the use thereof are disclosed.

A fiber processing device includes a drum having a plurality of openings on an outer peripheral surface, sieving a raw material containing fibers, and configured to rotate about a rotation axis, a housing that supports the drum, a guide portion (convex portion) provided on an outer peripheral surface of the drum; and a restriction portion (bearing) that restricts movement of the drum in a direction of the rotation axis by contacting the convex portion. At least one of the restriction portion and the guide portion is configured to rotate about an axis (rotation axis) orthogonal to the rotation axis.

In a defibrating apparatus, when a region, of a discharge path, including a discharge unit is a downstream discharge path, a region, of the discharge path, other than the downstream discharge path is an upstream discharge path, a region, of a screen, constituting the downstream discharge path is a downstream discharge screen, a region, of the screen, constituting the upstream discharge path is an upstream discharge screen, and a through-hole that causes a defibrating chamber to be in communication with the discharge path is a communication hole, the communication hole is provided on the screen such that the air is less likely to pass through the downstream screen than the upstream screen.

The invention relates to a process for producing non-woven fabric-like composite materials, novel non-woven fabric-like composite materials, articles made therefrom and their use. In particular the fabric-like composite materials are derived from shredded polymer-glued or polymer-coated paper products and coffee grounds as raw material.

A web transportation apparatus includes a mesh belt configured to be rotated to transport a web formed of a dry deposited material containing fibers and a striking member configured to strike a return section of the mesh belt to remove the material attached to the mesh belt. The striking member includes a striking bar and a striking lever. The striking bar is reciprocated to strike the mesh belt.

A defibration processing device is capable of efficient defibration in a multiple stage rotating part, and a fibrous feedstock recycling device. The defibration processing device has a first rotating part disposed on a side into which defibration feedstock flows, and a second rotating part disposed on a side to which defibrated material defibrated in the first rotating part is discharged. The first rotating part and second rotating part each have on the axis of rotation side thereof a base, and a protruding part protruding from the base in a direction away from the axis of rotation. A spacer is between the first rotating part and second rotating part. An external restriction plate protrudes from the stationary part side toward the spacer, and an internal restriction plate protrudes from the axis of rotation side of the first rotating part and second rotating part toward the stationary part.
