PROBLEM TO BE SOLVED: To provide a fiber bundle-bundling device for a loom, capable of supporting a sucking pipe through an end plug in high position accuracy in a state of keeping the air tightness, and capable of reducing the man-hour for assembly and disassembly of the sucking pipe and the end plug.;SOLUTION: The sucking pipe of the fiber bundle-bundling device is supported by a machine frame of the loom through the end plug 20, and the end plug 20 has a sucking pipe-supporting part 26 for supporting the sucking pipe in a state in which the end plug 20 is inserted into the terminal part of the sucking pipe. The sucking pipe-supporting part 26 has a rigid supporting part 27 capable of supporting the sucking pipe in a positioned state by being fitted in the inner surface of the terminal part of the sucking pipe, and a flexible seal part 28 integrated with the tip side of the rigid supporting part 27, and contacting with the inner surface of the sucking pipe supported by the rigid supporting part 27 in an air-tight state.;COPYRIGHT: (C)2011,JPO&INPIT
