Embodiment Construction

[0012] The present invention relates to a technique for solving the problem of continuously supplying new pulp sheets to the defibrator when the supply of the pulp sheets to the defibrator is exhausted when the pulp sheets extracted from the pulp base are supplied to the defibrator. The new and old sheets overlap and the interval between the old and new sheets is too large.

[0013] Below, while referring to figure 1 with figure 2 , a preferred embodiment of the manufacturing method of the fiber piling body of the present invention will be described.

[0014] First, refer to figure 1 The manufacturing apparatus of a fiber piling body suitable for carrying out the manufacturing method of a fiber piling body is demonstrated.

[0015] Such as figure 1 As shown, as a preferable example of the structure of the manufacturing apparatus 10 of a fibrous body, the pulp raw material unwinder 11, the pulp raw material conveyance mechanism 12, the defibrator 13, and the fiber stacker ...

Abstract

Provided is a method for producing a laminated fiber body in which pulp fiber acquired by defibrating, using a defibrator, a pulp sheet drawn from pulp stock is supplied to a stacking machine together with an air flow so as to acquire a laminated fiber body in which the pulp fiber has been deposited. In this method, when a second pulp sheet drawn from new pulp stock is to be supplied to the defibrator after a first pulp sheet supplied to the defibrator, the second pulp sheet is drawn at a conveying speed faster than the conveying speed of the first pulp sheet supplied to the defibrator, the conveying speed of the second pulp sheet is decelerated so that the tip of the second pulp sheet follows the end of the first pulp sheet, the tip of the second pulp sheet is set to be in a state of contacting or approaching the end of the first pulp sheet, and the second pulp sheet is supplied following the first pulp sheet.

Description

technical field [0001] The present invention relates to a method for manufacturing a fiber piling body. Background technique [0002] As a method for manufacturing absorbent bodies of absorbent articles such as sanitary napkins, panty liners, and disposable diapers, it is known to use a fiber stacker to stack pulp fibers and the like supplied into the duct together with the air flow, and to stack the fibers. A method in which the fibrous body is directly or wrapped with paper, air-permeable non-woven fabric, etc. to make an absorbent body. The pulp fibers supplied to the fiber stacker are obtained by defibrating a sheet (pulp sheet) derived from a pulp base material by a defibrating machine. When the sheet supplied to the defibrating machine meets the terminal, a new sheet is continuously supplied with the sheet, and the old and new sheets are overlapped or docked. [0003] It is known that when the sheets are supplied to the defibrating machine in a state where the sheets...
