Abstract
An apparatus for inserting flattened tubes into heat exchanger fins includes a guide inserted into at least one out of a plurality of cutaway portions for holding heat exchanger fins in the thickness direction. A guide holding unit holds the heat exchanger fins and the guide with a flattened tube holding unit in which flattened tubes are held in an intermittent arrangement with respect to the cutaway portions into which the guide has not been inserted. A flattened tube insertion driving unit inserts the flattened tubes held on the flattened tube holding unit into the cutaway portion with a platen that is caused to contact another edge in a width direction of the heat exchanger fins when the flattened tubes are inserted into the cutaway portions. Thereafter a compressing unit compresses the heat exchanger fins in the stacking direction.
