Abstract
Official abstract text for this publication.
A sheet manufacturing apparatus includes a drum unit having a plurality of openings, a housing unit covering the drum unit, a transport unit on which a material containing fibers passing through the openings is accumulated as a web and which transports the accumulated web, a first roller that abuts the web transported by the transport unit, and a first seal unit that is provided on a first side wall of the housing unit and comes into contact with the first roller.
First claim
Opening claim text (preview).
What is claimed is: 1 . A sheet manufacturing apparatus comprising: a drum unit having a plurality of openings; a housing unit covering the drum unit; a transport unit on which a material containing fibers passing through the openings is accumulated as a web and which transports the accumulated web; a first roller that abuts the web transported by the transport unit; and a first seal unit that is provided on a first side wall of the housing unit and comes into contact with the first roller. 2 . The sheet manufacturing apparatus according to claim 1 , wherein a peripheral speed of the first roller is faster than a transport speed of the web by the transport unit. 3 . The sheet manufacturing apparatus according to claim 1 , further comprising: a second roller that is positioned further on an upstream side than the first roller in a transport direction of the web; and a second seal unit that is provided on a second side wall facing the first side wall of the housing unit and comes into contact with the second roller. 4 . The sheet manufacturing apparatus according to claim 1 , wherein the transport unit includes a belt that transports the web, and wherein the apparatus further comprises a first belt support plate that faces the first roller to interpose the belt therebetween. 5 . The sheet manufacturing apparatus according to claim 3 , wherein the transport unit includes a belt that transports the web, and wherein the apparatus further comprises a second belt support plate that faces the second roller to interpose the belt therebetween. 6 . The sheet manufacturing apparatus according to claim 1 , wherein the transport unit includes a belt that transports the web, and wherein the apparatus further comprises a third roller that faces the first roller to interpose the belt therebetween. 7 . The sheet manufacturing apparatus according to claim 3 , wherein the transport unit includes a belt that transports the web, and wherein the apparatus further comprises a fourth roller that faces the second roller to interpose the belt therebetween.
