After that, the operation of pressing and fixing the both side edges of the edge of the holding mat 8 on the concave portion 81 side with the claws 31, 31 to the catalyst carrier S can be automatically and quickly performed.

  Further, a bucket 7 is provided below the catalyst carrier S, and after the mounting table 1 is further moved in the horizontal direction and the bucket 7 is raised to a position where the catalyst carrier S is supported by the cylinder 73, a pair of radial driving is performed. The pressing and fixing state of the holding mat 8 by the mechanism and the axial direction driving mechanism and the insertion state of the claws 31 and 31 into the back surface of the end edge of the holding mat 8 on the concave portion 81 side, 2 is configured to receive and accommodate the catalyst carrier S around which the holding mat 8 is wound in the bucket 7 by driving the clamping mechanism 4b to release the clamping state of the catalyst carrier S by 2. Can be accommodated in the bucket 7 without adding.

  If the mounting table 1 is not configured to be movable by the horizontal action mechanism 5, the catalyst carrier S cannot be received and accommodated in the bucket 7, and in this case, the catalyst around which the holding mat 8 is wound. A special device (robot arm or the like) for holding and transporting the carrier S from above is required, which increases the equipment cost and takes time for accommodation.

  Further, since the bucket 7 is provided with the transfer mechanism 71, the catalyst carrier S received and accommodated in the bucket 7 can be quickly moved to another position.

  Although the present embodiment has been described above, the present invention is not limited to the above-described embodiment, and design changes and the like within a scope not departing from the gist of the present invention are included in the present invention.

  For example, in the embodiment, the horizontal driving mechanism 5 that moves the mounting table 1 substantially horizontally in synchronization with the winding movement speed of the holding mat 8 by the rotation driving mechanism 4 a is slower than the winding speed of the holding mat 8. However, it is sufficient that the speed is at least the same.

  In the embodiment, the rotational drive mechanism 4a and the horizontal drive mechanism 5 are driven by the same motor M or air with different gear ratios, but may be driven by independent motors or the like.
