Patent ID: 8163124

Claim:
A method for manufacturing a sheet-shaped body in which a powder particle layer is sandwiched between a base sheet to which a bonding agent is applied and a covering sheet so as to be bonded into an integral body, comprising: supplying powder particles from a source container into a concave groove of a face of a temporary receiving roller during rotation of the temporary receiving roller, wherein the supplied powder particles form the powder particle layer; holding the powder particle layer onto the temporary receiving roller with a guide member extending over an arc length of the temporary receiving roller during rotation of the temporary receiving roller; shifting the powder particle layer along a first path including a first path first portion encompassing an arc face portion of the temporary receiving roller; shifting the base sheet along a second path including a second path first portion, wherein at the second path first portion the base sheet is moved between a receiving and transferring roller and the temporary receiving roller making contact with the powder particle layer on the temporary receiving roller, transferring the powder particle layer onto the base sheet as the base sheet is moved to the second path first portion during rotation of both the receiving and transferring roller and the temporary receiving roller; shifting the covering sheet along a third path while in a held state on a contact-bond fixing roller; and bonding the base sheet, the powder particle layer and the covering sheet into an integral form on the third path during rotation of the contact-bond fixing roller; and wherein the powder particle layer is shifted along the first path first portion at a shifting speed that is less than respective shifting speeds of the base sheet along the second path and the covering sheet along the third path, such that the powder particle layer transferred onto the base sheet is formed into a linear shape or a blurred pattern in a shifting direction.
