Abstract
Provided is a sheet manufacturing apparatus capable of desirably adjusting the thickness of the sheet, and forming sheets with highly uniform thickness or grammage. A sheet manufacturing apparatus configured to make a sheet from defibrated material of defibrated paper includes: a drum unit having a cylinder with a defibrated material storage space inside and multiple openings through which the defibrated material passes formed in the outside of the cylinder; an accumulator configured to accumulate the defibrated material that past the openings, forming a deposit; and a housing configured to enclose the drum unit and the accumulator, the housing having a vent through which air passes between the drum unit and the accumulator.
Claims13
A sheet manufacturing apparatus, comprising:
- a drum unit having (i) a cylinder with a defibrated material storage space inside and (ii) a plurality of openings configured to allow for defibrated material to pass through, the plurality of openings being formed in the outside of the cylinder;
- an accumulator comprising a belt, the accumulator configured to accumulate the defibrated material that passes through the plurality of openings, the accumulated defibrated material forming a deposit;
- and
- a housing configured to enclose the drum unit,
- wherein the housing has a vent through which air passes between the drum unit and the accumulator, and
- wherein the housing includes a first longitudinally extending portion and a second longitudinally extending portion, the vent having a longitudinal axis and longitudinally extending in a same direction as the first longitudinally extending portion and as the second longitudinally extending portion.
A sheet manufacturing apparatus, comprising:
- a drum unit having (i) a cylinder with a defibrated material storage space inside and (ii) a plurality of openings configured to allow for defibrated material to pass through, the plurality of openings being formed in the outside of the cylinder;
- an accumulator comprising a belt, the accumulator configured to accumulate the defibrated material that passes through the plurality of openings, the accumulated defibrated material forming a deposit;
- and
- a plurality of seals disposed circumferentially on the outside of the drum unit,
- wherein adjacent seals of the plurality of seals are configured to move towards or away from each other along a circumference of the outside of the drum unit.
A sheet manufacturing apparatus for making a sheet from defibrated material of defibrated paper, the apparatus comprising:
- a drum unit having (i) a cylinder with a defibrated material storage space inside and (ii) a plurality of openings through which the defibrated material passes, the plurality of openings formed in the outside of the cylinder;
- an accumulator comprising a belt, the accumulator that accumulates the defibrated material that passes through the openings, the accumulated defibrated material forming a deposit;
- and
- a housing that encloses the drum unit,
- wherein the housing has a vent through which air passes between the drum unit and the accumulator, and
- wherein the housing includes a first longitudinally extending portion and a second longitudinally extending portion, the vent having a longitudinal axis and longitudinally extending in a same direction as the first longitudinally extending portion and as the second longitudinally extending portion.
