the succeeding step and one piece of material is left on the flat lay passage 270 while the other excessive material pieces are excluded and returned to within the storage container 250 the hose material x picked up to within the guide pipe 261 by an ascent of the pickup bar 262 is then detected at its lowermost end portion by the sensor 201 during the ascent of the bar 262 as a result the bar 262 stops ascending and places the picked up hose material x to a specified position in the guide pipe 261 state of solid line in fig2 as to the detection of material by the sensor 201 the shutters 221 and 222 are opened causing a suction force from the suction source a to act on the interior of the conveyance pipe 271 through the flat lay passage 270 so that the hose material x picked up into the guide pipe 261 is sucked up from its lowermost end portion into the conveyance pipe 271 state of dot chain line in fig2 at this point by stopping the sucking operation of the pickup bar 262 the hose material x sucked up at its lowermost the portion into the conveyance pipe 271 is separated from the pickup bar 262 and suctionally conveyed up to the one end side of the flat lay passage 270 through the pipe 271 and reserved in a bulk form by the blocking plate 273 state of dot chain line in fig2 when the hose material x is reserved in bulk by the blocking plate 273 of the flat lay passage 270 the reserved material is detected.
