Apparatus and method for manufacturing multilayer felt

An apparatus for manufacturing multilayer felt, comprising:

• an upper mold and a lower mold of a press mold which are disposed in a hermetic molding box in an up and down direction, and press chip felt to form a felt product having a desired shape;
• a vacuum source which provides vacuum to a plurality of vacuum suction gates formed in the upper mold;
• a chip felt supply line which supplies the chip felt between the upper mold and the lower mold;
• and
• a blower fan which is connected to a rear end portion of the chip felt supply line and supplies the chip felt toward the molds,
• wherein a first chip felt supply gate for supplying first chip felt and a second chip felt supply gate for supplying second chip felt are in parallel connected to a front end portion of the chip felt supply line,
• wherein the first chip felt is supplied from the first chip felt supply gate to between the upper mold and the lower mold, and firstly adsorbed by vacuum pressure to the vacuum suction gates of the upper mold,
• wherein the second chip felt is supplied from the second chip felt supply gate, and secondly adsorbed by vacuum pressure on a surface of the first chip felt to be stacked on the first chip felt,
• wherein a vacuum suction shut-off device, which closes desired vacuum suction gates among the plurality of vacuum suction gates, is mounted above the upper mold, and
• wherein the vacuum suction shut-off device includes:
• a shut-off plate which has a structure having a rack formed on an upper surface thereof, and shuts off the desired vacuum suction gates among the plurality of vacuum suction gates;
• a pinion which is engaged with the rack of the shut-off plate;
• and
• a motor which is coaxially connected with the pinion, and provides rotational power to the pinion to selectively moves the shut-off plate above the plurality of vacuum suction gates.
