Claim Text:
1. A method for producing a sandwich structure comprising a pattern of particulate material, the method comprising the steps of: advancing a carrier material to a carrier support structure, the carrier support structure comprising a shell and a carrier support area, wherein the shell defines an outer circumferential surface, and wherein the carrier support area protrudes radially outward from the outer circumferential surface of the shell; rotating the carrier support structure; advancing the carrier material onto the carrier support structure, wherein the carrier material defines a support region and an indentation region, wherein the carrier material is supported by the carrier support structure in the support region and is unsupported by the carrier support structure in the indentation region; rotating a transfer device to a loading position, wherein the transfer device comprises recesses; metering a particulate material into the recesses of the transfer device; rotating the transfer device to a discharging position; transferring the particulate material into the indentation region of the carrier material; advancing a cover material adjacent to the carrier material; and bonding the cover material to the carrier material in the support region of the carrier material, wherein the particulate material is sandwiched between the carrier material and the cover material.
