Problems solved by technology

In addition, when the sheet is formed by a dry method, if the substance used as the binder is a liquid, the fibers will aggregate and it will be difficult to pass through the mesh of a sieve, so it is difficult to use a sieve to perform uniform accumulation and molding.

Abstract

A sheet manufacturing apparatus includes: a defibrating unit which defibrates a defibration object including fibers; a cylinder unit which allows a defibrated material which is defibration-processed in the defibrating unit and introduced via an introduction port to pass through a plurality of holes that is on a cylindrical surface by rotating; a supplying unit which is provided with a supply port which supplies additive agents that bond the plurality of fibers in the cylinder portion; and a bonding unit which forms a sheet by bonding the fibers and the additive agents.

Description

technical field [0001] The present invention relates to a sheet manufacturing device. Background technique [0002] Conventionally, a sheet-like or film-like molded body has been obtained by accumulating fibrous substances and exerting a binding force on the accumulated fibers. As a typical example thereof, paper is produced by a papermaking (papermaking) method using water. Currently, papermaking is also widely used as one of the methods for producing paper. Paper produced by the papermaking method generally has a structure in which, for example, cellulose fibers derived from wood, etc. )) so that the parts of each other adhere to the structure. [0003] On the other hand, Patent Document 1 discloses a method for producing a waste paper fiber molded product using a dry-type waste paper defibrating machine that does not use water. According to this production method, it is described that a mixture of a synthetic resin binder and waste paper fibers is pressurized and heat...
