proposed is a paper gathering and feeding method , a device therefor , and a rotation member acting sufficiently also on any deformed notes at the time of gathering , and at the time of feeding , feeding is not prevented irrespective of the plasticity deformation , and an object thereof is to reduce the exchange frequency and maintenance of the rotation member , extend the continuous operation time of the paper gathering and feeding device , and realize comprehensive reduction of production cost , service cost , and the like . with respect to a paper gathering and feeding method or a device therefor performing a gathering process for dropping paper to be transferred in a transfer section to gather the same in a gathering section , and a feeding process for feeding the paper gathered in the gathering section to the transfer section , a rotation member provided with a changeable piece changeable with a radius distance between a tip section and a rotation axis is provided in the vicinity of a coupling section between the transfer section and the gathering section , and at the time of the gathering process , the rotation member is so formed as to rotate in a gathering direction to slap down the paper using the changeable piece with the wider radius distance , and at the time of the feeding process , the rotation member rotates in a feeding direction to perform the feeding allowance operation to allow the paper to be fed .
