PROBLEM TO BE SOLVED: To provide a device for feeding a trim of paper, which can smoothly feed the trim by eliminating a hindrance to the feeding of the trim, without employing a double-pipe structure, in consideration of the problem that a blast pipe narrows a trim feeding passage because of the double-pipe structure wherein the blast pipe bringing about an ejector effect is positioned in a feed pipe, though a structure for sucking the trim into the feed pipe by using the ejector effect is employed to feed the trim to trim treatment equipment etc. SOLUTION: A chamber 31 communicating with the blast pipe 40 is provided in the state of being wound around the feed pipe 30, one end of which faces the produced trim T, and a nozzle slit 32 for communicating with the feed pipe 30 is provided on the side of one end of the chamber 31, so that feeding air can be blown out into the feed pipe 30 from the nozzle slit 32. In this case, the feeding air is subjected to a Coanda effect, so as to flow in the direction opposite to the side of the suction of the trim T. The trim T is sucked in by virtue of the ejector effect using the feeding air, and fed to the trim treatment equipment by the feeding air. COPYRIGHT: (C)2007,JPO&INPIT
