The

As described above, according to the slip sheet cleaning apparatus according to the present invention, the brush processing for rough dust removal by the roll brush 23 (27) and the linear brush 24 (28) is performed in multiple stages, and then the clean rollers 14, 15 are performed. The dust removal process can be effectively performed by performing the finish dust removal according to the above.
Further, in the brush cleaner unit 4, the interleaf P is conveyed in a vertical state, and the dust is removed by the roll brush 23 (27) and the linear brush 24 (28) arranged in the vertical direction. The depth of the apparatus can be shortened, and the installation space can be reduced.
Furthermore, since the brush is covered with the casings 19 and 20 in the brush cleaner portion 4 having a vertical structure, the dust removed by the brush process can be prevented from being scattered around. Moreover, since the ducts 19a and 20a for suction are provided in the lower part of the casing, dust can be easily collected by sucking from the ducts 19a and 20a, and maintenance can be facilitated.

In the above embodiment, the case where the slip sheet P before dust removal on the input table 8 is manually inserted into the carry-in port 2a has been described as an example, but the slip sheet P is loaded into the automatic machine. It is good also as a structure inserted in 2a.
